Blue hour at Banff's Two Jack Lake. It often pays to beat the sun.
"The blue hour occurs when the Sun is far enough below the horizon so that the sunlight's blue wavelengths dominate due to the Chappuis absorption caused by ozone. Since the term is colloquial, it lacks an official definition similar to dawn, dusk, and the three stages of twilight. Rather, it refers to a state of natural lighting that usually occurs around the nautical stage of the twilight period (at dawn or dusk)." Wikipedia
The lake is named after Jack Stanley, who operated a boat concession on lake Minnewanka at one time, and Jack Watters, who worked for the mines in Bankhead, a town which flourished at the base of Cascade Mountain just after the turn of the century.
Thanks for taking a look.
Enjoy a wonderful Sunday and week ahead!
streets of Rethymno, Crete
Rethymno (Greek: Ρέθυμνο, [ˈreθimno], also Rethimno, Rethymnon, Réthymnon, and Rhíthymnos) is a city of approximately 40,000 people in Greece, the capital of Rethymno regional unit on the island of Crete, a former Latin Catholic bishopric as Retimo(–Ario) and former Latin titular see.
Rethymno was originally built during the Minoan civilization (ancient Rhithymna and Arsinoe). The city was prominent enough to mint its own coins and maintain urban growth. One of these coins is today depicted as the crest of the town: two dolphins in a circle.
This region as a whole is rich with ancient history, most notably through the Minoan civilisation centred at Kydonia east of Rethymno. Rethymno itself began a period of growth when the Venetian conquerors of the island decided to put an intermediate commercial station between Heraklion and Chania, acquiring its own bishop and nobility in the process. Today's old town (palia poli) is almost entirely built by the Republic of Venice. It is one of the best-preserved old towns in Crete.
From circa 1250 the city was the see of the Latin Diocese of Retimo, which was renamed Retimo–Ario after the absorption in 1551 of the Diocese of Ario and as suppressed only after the Turkish conquest.
The town still maintains its old aristocratic appearance, with its buildings dating from the 16th century, arched doorways, stone staircases, Byzantine and Hellenic-Roman remains, the small Venetian harbour and narrow streets. The Venetian Loggia houses the information office of the Ministry of Culture and Sports. A Wine Festival is held there annually at the beginning of July. Another festival, in memory of the destruction of the Arkadi Monastery, is held on 7–8 November.

Ok, I'm sitting on a chair, very comfortable. And the change is sure to come. But before I keep rocking back and forth with the idea of diving out of my absorption – chosen voluntarily and much longer than expected – I now take a little cautious step forward ;-) I haven't been on Flickr for such a long time and have neither posted a photo nor have I looked at any of yours – I have a lot to catch up I guess ... I hope you will be patient with me. The last year of the pandemic has changed a lot for everyone and I still have a lot to do – at least that's how it feels. But I really missed it here I must notice ... I hope your Christmas was vibrant and beautiful, we see each other – and take care of you :-)

Ok, ich sitze auf einem Stuhl, ganz gemütlich. Und die Veränderung kommt bestimmt. Aber ehe ich immer weiter hin und her schaukele mit der Überlegung aus der Versenkung – freiwillig gewählt und viel länger als gedacht – hervorzutauchen, mache ich jetzt doch einmal einen kleinen vorsichtigen Schritt vorwärts ;-) Ich war jetzt so fast unendlich lange nicht mehr auf Flickr unterwegs und habe weder ein Foto gepostet noch habe ich welche von Euch betrachtet – da habe ich wohl sehr sehr viel nachzuholen ... Ich hoffe, Ihr habt Verständnis dafür. Durch das letzte Jahr der Pandemie hat sich für alle viel verändert und ich habe auch weiterhin einiges zu tun – jedenfalls fühlt es sich so an. Aber vermisst habe ich es hier doch ziemlich, merke ich ... Hoffentlich war Euer Weihnachten schwingend und schön, wir sehen voneinander – und passt auf Euch auf :-)
Excerpt from youractionsmatter.ca/bee-thankful/:
Bee Thankful
• Bees are vital to the preservation of ecological balance and biodiversity in nature. They provide one of the most recognizable ecosystem services, pollination, which is what makes most food production possible.
• One third of all the food we eat depends on bees, and of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees.
• Honeybees alone pollinate 80% of all flowering plants, including more than 130 types of fruits and vegetables.
• The journey of bees begins with manure and fertilizer. It is used to enrich the soil, providing essential nutrients that help seeds germinate and plants grow.
• Water, a fundamental element for life, aids in the absorption of these nutrients from the soil, allowing the plant to grow strong and healthy.
• As the plant matures on the fertile land, it develops vibrant flowers rich in nectar and pollen.
• Bees are attracted to these flowers for their nectar, which they use to create honey, and in the process, they pollinate the plant, contributing to its reproductive cycle and the growth of new plants.
• This illustrates a symbiotic relationship, where bees and plants rely on each other for survival and growth.
• Despite their profound importance for the food we eat, bee populations are declining at an alarming rate.
• Last winter, Canada had its largest honeybee colony loss in the past 20 years, with 46% of colonies perishing nationally.
• Global warming, pesticide use, habitat destruction, and air pollution all contribute to bee mortality.
• By understanding the vital role bees play in our ecosystem and food production, and making conscious choices to help, we can contribute to the conservation of bees and the vital services they provide.
The Missouri-Kansas-Texas Railroad had a sole route into Houston from the west, by way of Smithville, Sealy, and the namesake Katy. After absorption by the Union Pacific in 1988, the route out of Houston was deemed excessive and was severed in Katy, with the trackage to the west remaining. Since then, UP has kept traffic on this former mainline at a slow and steady pace. Once a week, a local based in Smithville makes an eastbound run towards the city. Some weeks it makes it as far as Katy, some weeks it doesn't. Today's train is a measly one car for Builders FirstSource on the west side of Katy.
Also of note, the leader of today's train. UP 1371 was built for the MKT in 1968 as GP40 207, sold off the roster with the UP acquisition, and made its way into SP hands after a rebuild program by Morrison-Knudsen. It's safe to say this locomotive has seen plenty of Texas soil in its previous lives.

One of the gems in the renovated castle is the large council room on the first floor. This festive hall is available for council meetings as well as for cultural events. As a clear contrast to the late Gothic form of the windows, with partial reuse of recovered from the moat original Gewändesteinen, here a modern exposed concrete ceiling was pulled. In the elongated cavities of the coffered ceiling, the lighting panels, sound absorption material, the sound system and electrical installation were usefully integrated.
The second floor and attic floor in the west wing was expanded as a multifunctional office and used as such for many years. A suitable furnishing, the installation of room dividers and appropriate greening provided here for a pleasant atmosphere. The enormous room height on the second floor was usefully used as a shelf by a suspended gallery.
After the completion of the Technical Town Hall in 2003, numerous rooms of the castle were reused. Thus, on the second floor of the west wing, the gallery was rebuilt, so that here a large, multi-functional event space was created - the "Motte".
The colours of ice, from pure white to blue to black, depend on the levels of air bubbles and other inclusions in the ice. The newest ice when it first freezes has the most air bubbles and the whitest colour. As ice gets older and is subject to compression by overlying snow and ice, the air bubbles are forced out and/or compressed with more absorption of the red and orange wavelengths and more reflections of the blue wavelengths. The oldest blue and black ice can be over a million year old. This image shows a mixture of old and newer ice near a cliff at the terminus of the Jorge Montt Glacier, Patagonia.

The blue hour is the period of twilight when the Sun is at a significant depth below the horizon and residual, indirect sunlight takes on a predominantly blue shade, which differs from the one visible during most of a clear day, which is caused by Rayleigh scattering.
The blue hour occurs when the Sun is far enough below the horizon so that the sunlight's blue wavelengths dominate due to the Chappuis absorption caused by ozone. Since the term is colloquial, it lacks an official definition similar to dawn, dusk, and the three stages of twilight. Rather, it refers to a state of natural lighting that usually occurs around the nautical stage of the twilight period (at dawn or dusk).
----------------------------------------------------------------------------------------------
La hora azul es el período del crepúsculo en el que el Sol se encuentra a una profundidad significativa por debajo del horizonte y la luz solar indirecta residual adquiere un tono predominantemente azul, que difiere del que se ve durante la mayor parte de un día despejado, que es causado por la dispersión de Rayleigh.
La hora azul ocurre cuando el Sol está lo suficientemente por debajo del horizonte para que dominen las longitudes de onda azules de la luz solar debido a la absorción de Chappuis causada por el ozono. Dado que el término es coloquial, carece de una definición oficial similar a amanecer, anochecer y las tres etapas del crepúsculo. Más bien, se refiere a un estado de iluminación natural que generalmente ocurre alrededor de la etapa náutica del período crepuscular (al amanecer o al atardecer).

The Croak Constant encapsulates the interaction between incident spectral light, biological absorption by the amphibian and the optical scattering introduced by vintage lens bokeh. This expression highlights the convergence of physical optics and biological processes in a single conceptual framework:
K_c = (L_λ × σ_a × S_b) / Φ_c
Where:
K_c = Croak constant (arbitrary units)
L_λ = Spectral luminance at wavelength λ (light intensity)
σ_a = amphibian absorption spectrum (skin light absorption)
S_b = Bokeh scattering coefficient (vintage lens optical effect)
Φ_c = Biological photon efficiency (rate of conversion to croak energy)

7. Rhône Glacier – A Landscape in Transition
September 2023
90 × 60 cm, Alu-Dibond
Italiano
Ai piedi del ghiacciaio del Rodano, nel canton Vallese, nasce il fiume Rodano. Un tempo, la lingua glaciale si estendeva ben oltre nella valle, fino al Grand Hotel di Gletsch. Oggi il ghiaccio si è ritirato di centinaia di metri e, dove un tempo si trovava una spessa lingua di ghiaccio, è apparso un lago turchese di acqua di fusione, dal quale l’acqua si riversa nella valle attraverso una cascata.
Il lago si sta ingrandendo rapidamente. Il ghiacciaio del Rodano è tra quelli che scompaiono più velocemente nelle Alpi. La sua lingua glaciale è coperta di detriti scuri e polvere, che aumentano l’assorbimento della luce solare e accelerano la fusione. Sulla superficie dell’acqua galleggiano blocchi di ghiaccio, resti della fronte glaciale in disgregazione.
L’acqua di fusione alimenta il giovane Rodano, che da questa fragile origine cresce fino a diventare uno dei più grandi fiumi d’Europa. Quello che rimane è un paesaggio in trasformazione visibile: dal ghiaccio permanente all’acqua effimera, da ghiacciaio a ricordo.

Am Fuss des Rhonegletschers im Wallis entspringt der Fluss Rhone. Einst reichte die Gletscherzunge weit ins Tal hinab, bis zum Grand Hotel in Gletsch. Heute hat sich das Eis um mehrere hundert Meter zurückgezogen und an der Stelle, wo früher eine dicke Eiszunge lag, ist ein türkisfarbener Schmelzwassersee entstanden, aus dem das Wasser über einen Wasserfall ins Tal stürzt.
Der See wächst rasant. Der Rhonegletscher zählt zu den am schnellsten schrumpfenden Gletschern der Alpen. Die Gletscherzunge ist mit dunklem Geröll und Staub bedeckt, was die Sonnenlichtaufnahme erhöht und die Eisschmelze beschleunigt. Auf der Wasseroberfläche treiben Eisschollen, Überreste des kalbenden Gletscherrands.
Das Schmelzwasser speist die junge Rhone, die aus dieser fragilen Quelle zu einem der mächtigsten Flüsse Europas heranwächst. Zurück bleibt eine Landschaft im sichtbaren Wandel, von dauerhaftem Eis zu temporärem Wasser, vom Gletscher zur Erinnerung.

At the foot of the Rhône Glacier in the Swiss canton of Valais, the Rhône River is born. Once, the glacier’s ice extended far into the valley, reaching as far as the Grand Hotel in Gletsch. Today, the ice has retreated by hundreds of meters, and where a thick tongue of ice once lay, a turquoise meltwater lake has formed. From there, the water cascades down into the valley via a waterfall.
The lake is growing rapidly. The Rhône Glacier is among the fastest disappearing glaciers in the Alps. Its ice tongue is covered in dark debris and dust, which increase the absorption of sunlight and accelerate melting. On the surface of the lake, chunks of ice float, remnants of the calving glacier front.
Meltwater from the glacier feeds the young Rhône, which grows from this fragile source into one of Europe’s great rivers. What remains is a visibly changing landscape, from permanent ice to temporary water, from glacier to memory.
The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails. William Arthur Ward.
William Arthur Ward (December 17, 1921–March 30, 1994) was an American motivational writer.
Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. Winds have various aspects: velocity (wind speed); the density of the gas involved; energy content or wind energy. The wind is also a critical means of transportation for seeds, insects, and birds, which can travel on wind currents for thousands of miles.
In human civilization, the concept of wind has been explored in mythology, influenced the events of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity, and recreation. Wind powers the voyages of sailing ships across Earth's oceans. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. When winds become strong, trees and human-made structures are damaged or destroyed.
Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind also affects the spread of wildfires. Winds can disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations. When combined with cold temperatures, the wind has a negative impact on livestock. Wind affects animals' food stores, as well as their hunting and defensive strategies.
The wind is caused by differences in atmospheric pressure which is mainly caused by temperature difference. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator. Globally, the two major driving factors of large-scale wind patterns (the atmospheric circulation) are the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and the rotation of the planet. Outside the tropics and aloft from frictional effects of the surface, the large-scale winds tend to approach geostrophic balance. Near the Earth's surface, friction causes the wind to be slower than it would be otherwise. Surface friction also causes winds to blow more inward into low-pressure areas. Source Wikipedia.

1340 ‘Trojan’ was built by the Avonside Engine Company of Bristol in 1897 (Works No. 1386) for Messrs Dunn & Shute of Newport Town Dock. She was purchased by the Alexandra Docks Railway in 1903, remaining unnumbered. This company owned around 100 miles of dock sidings in the Newport (South Wales) area and a 'main' passenger-carrying line of 10 miles or so.
On absorption of the Alexandra Docks Railway into the Great Western in 1923, ‘Trojan’ received the number 1340. She moved freely around GWR territory, and although based mainly at Cardiff Cathays and Radyr depots also worked for a time in Oswestry and Greenford, London. Withdrawn from Cardiff by the GWR in July 1932, it was sold to the Netherseal colliery at Burton-on-Trent, who passed it on to Alders (Tamworth) Ltd in 1947.
After several years of negotiations she was finally released to one of the Didcot regular workforce, arriving at the depot in April 1968. Source: didcotrailwaycentre.org.uk/article.php/59/1340-trojan
Hippity hop! The desert cottontail eats grasses, cacti, bark and twigs and mesquite. They live, well, in deserts of California and US Southwest. They are close cousins of Eastern Cottontails but are lighter colored to minimize absorption of sun's heat and have larger ears to help radiate body heat into the air. I came across so many of them early in the morning, yet none later in the day when it gets warmer.
Fun fact: When they are alarmed, cottontails can run up to 20 miles per hour! Keep up with that coyotes and birds of prey!
I want to thank everyone who commented or faved this picture! I would have never thought it would be this well liked :)
THANKS SO MUCH ALL !!!
Antioplelle (Antiopella cristata) – La Lauve –Cap d’Antibes - France
Delicate and elegant, Antiopella cristata glides among algae and hydroids like a colorful veil. Its translucent body reveals the intriate harmony of its internal organs, while its cerata — long, iridescent filaments — sway gently with the current.
Both ornamental and vital, each cerata contains a digestive diverticulum, an extension of the intestine where digestion and absorption take place. But this fragile structure also hides a clever defense strategy: nematocysts harvested from its tinging prey, mainly hydroids, are stored there, ready to deter
potential predators.
Under the light, the cerata glow with a crystalline radiance, highlighting the functional beauty shaped by evolution.
This image was captured off the coast of Cap d’Antibes, at the dive site La Lauve.
Using a Nikon D800E in an Aquatica housing, paired with a 105 mm macro lens, an SMC - 1 (2.3x) wet lens, and a snoot mounted on a Backscatter Mini Flash 2, I isolated texture, form, and light at F/22 to reveal the graphic details of this elegant biological ingenuity.
This Danaus genutia butterfly is also known as the "Common Tiger" due to its bright orange color with dark stripes. Similar in appearance to the Monarch commonly found in the US, Danaus genutia can be found in India and Sri Lanka. This specimen is in a black frame with white background and species name located inside.
Tirumala limniace, the blue tiger is a butterfly found in South Asia and Southeast Asia that belongs to the crows and tigers, that is, the danaid group of the brush-footed butterfly family. This butterfly shows gregarious migratory behaviour in southern India.
In general, all butterflies can directly absorb heat from the sun via their wings to facilitate autonomous flight. Studies on blue tiger butterflies show that high-intensity light significantly increased flight activity. Blue tiger butterflies have a wing surface color that is composed of both light and dark colors. The dark areas on the wing surfaces are the heat absorption areas that allow for the facilitation of autonomous flight.
Many thanks to all those who view, comment and or fave my photos....It is greatly appreciated ......Chandana ❤️

Colourful lady spotted in La Villette
Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, green, blue and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates.
Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.
The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).
-our, -or
Most words ending in an unstressed -our in British English (e.g. colour, flavour, honour, harbour, neighbour, rumour, labour, humour) end in -or in American English (cf. color, flavor, honor, harbor, neighbor, rumor, labor, humor). Wherever the vowel is unreduced in pronunciation, this does not occur: e.g. contour, velour, paramour and troubadour are spelled thus the same everywhere.
The Trona Railroads power perfectly mirrors the UP’s absorption of the SP as armor yellow took over. Roughly 30 years later, history repeats itself somewhat with most of the SP heritage sidelined in the shops, Armor Yellow making up most of Trona's consists today. Only TRC 2006, their last operating tunnel motor (hopefully for the time being), still rolls toward Searles.

Radioactive forest.
The name "Red Forest" comes from the ginger-brown colour of the pine trees after they died following the absorption of high levels of radiation from the Chernobyl accident on 26 April 1986. In the post-disaster clean up operations, the Red Forest was bulldozed and buried in "waste graveyards". The site of the Red Forest remains one of the most contaminated areas in the world today.
The Aber Swing Bridge, also known as the Pont yr Aber and Caernarfon swing bridge, is a pedestrian swing bridge in Gwynedd, Wales. This footbridge crosses over the Afon Seiont from the foreshore to the Watergate entrance in the centre of Caernarfon near Caernarfon Castle.
This bridge swings to one side to allow boats to enter or leave the harbour. It replaced a Victorian bridge which itself had replaced a ferry across the river Seiont. It leads from Caernarfon town to the parkland at Coed Helen.

The small building with castellated top, west of the bridge, was built in 1822 for the operator of the Coed Helen ferry. The Pritchard family of boat owners and builders ran the ferry from c.1859. In 1878 David Pritchard was praised for his prompt action to save a militiaman (volunteer soldier) who fell between the quay and boat while boarding. David died, aged 76, in 1884.
The first swing bridge, known as Pont yr Aber, was completed in 1899, amid arguing over compensation for loss of the ferry trade. A gas engine powered the swing mechanism. The bridge was too small to justify hydraulic power, which would have been ideal.
The metalwork was painted “stone colour” (off-white) to minimise heat absorption from sunshine. Excess heat would have distorted the ends of the swing span. White paint was rejected as it would soon have looked dirty. Tolls were levied on pedestrians and carriages.
The bridge was replaced by the current pedestrian bridge in 1970. You can still see some of the wooden supports for the original bridge as you cross.
A drive led from the ferry to Coed Helen house, thought to date from the early 17th century. The house belonged to a succession of influential families and is now part of a caravan park.
On the hill between the river and house stands a summerhouse, built in the 18th century. At various times, the military used the area for training and keeping watch on the Menai Strait. A battery of guns at Coed Helen was fired on important occasions, including in 1847 to salute Queen Victoria and Prince Albert and their children.
My second pass at this object. Last year I approached this mostly using narrowband filters. I used some of that data again here but really couldn't find much additional detail in it. This is shot relatively short using R,G,B filters with a black and white camera and many more exposures in just black and white... to get as much of the faint outlying structure as possible. I am lucky to live in a near-rural area and apparently it's dark enough to catch details in these dark parts of the nebula and bring them to life.
"The Cocoon Nebula, also known as IC 5146, is a relatively well-known nebula located in the constellation Cygnus, about 3,000 light-years from Earth. It is a combination of both an emission and reflection nebula, surrounded by a dark molecular cloud. Here’s an overview of its main characteristics:
Structure and Composition:
The Cocoon Nebula is a star-forming region that contains ionization, dust absorption and reflection. It appears as a small, bright core (the "cocoon") surrounded by the dark lanes of dust.
In the central region, new stars are forming, and their intense radiation ionizes the surrounding hydrogen gas, causing it to glow with the characteristic red color of an emission nebula.
At the same time, the dust around the young stars reflects their light, making parts of the nebula visible as a reflection nebula.
Star Formation:
The Cocoon Nebula contains a young star cluster known as Collinder 470, which is embedded in the nebula.
The star at the center of the nebula is particularly young and massive. Its energy drives the emission that we see from the surrounding gas. This star, along with others in the nebula, is in the early stages of stellar evolution.
Dark Nebula (Barnard 168):
A key feature of the Cocoon Nebula is its association with a long, dark cloud known as Barnard 168, which forms a "trail" leading away from the nebula.
This dark nebula absorbs background light and obscures stars behind it, creating a stark contrast with the glowing core of the Cocoon Nebula.
Size and Distance:
The Cocoon Nebula spans about 12 light-years across, with the surrounding dark nebula stretching even further.
It is located about 3,000 light-years away from Earth, making it a relatively close target for amateur astronomers with telescopes.
Visibility:
Although the Cocoon Nebula is relatively faint, it can be observed with medium to large telescopes, particularly under dark skies. It is located near the star Pi Cygni in the constellation Cygnus."

My first pass at this object. It appears this is one of those objects that needs more than narrow band filters. I am hoping to collect a lot more data in the future particularly in regular rgb to get color in the dust and reflection areas.

One of the key technical features that distinguished the Minerva AM Convertible Town Cabriolet 1928 was its advanced suspension system. It was built with a beefed-up version of the conventional leaf-spring suspension that was common at the time. This system used a double-spring setup that allowed for better shock absorption, ensuring a smoother ride even on bumpy roads.
The car was powered by a robust 6.6-liter inline-six engine that was capable of 65 horsepower. This engine was mated to a four-speed manual transmission that provided excellent control over the car's power output. The car could easily accelerate from 0 to 60 mph in just 12 seconds, making it one of the fastest cars of its time.
The Minerva AM Convertible Town Cabriolet 1928 was also notable for its exceptional braking system. It was one of the first cars of its time to be equipped with hydraulic brakes, which provided more control and better stopping power than the mechanical brakes that were commonly used at the time. The car's braking system was so advanced that it even came with a failsafe system that prevented the car from rolling backward on steep hills.
1928: The body of the car is designed by Belgian coachbuilder Joseph Figoni, known for his artistic and aerodynamic designs
DEVON is a large county in southwestern England
The name "Devon" derives from the ancient Dumnonia, which was home to the independent kingdom of Brythonic Celtic speaking people who inhabited this area of the southwestern peninsula of Britain continuously from through the Roman era until partial absorption into the English-speaking Kingdom of Wessex some time in the eighth or ninth century.
The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world. It is located in the Midway Geyser Basin.
The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature of the water that favors one bacterium over another. The center of the pool is sterile due to extreme heat.
The deep blue color of the water in the center of the pool results from the intrinsic blue colour of water, itself the result of water's selective absorption of red wavelengths of visible light. Though this effect is responsible for making all large bodies of water blue, it is particularly intense in Grand Prismatic Spring because of the high purity and depth of the water in the middle of the spring. The spring is approximately 250 by 300 feet (80 by 90 m) in size and is 160 feet (50 m) deep. The spring discharges an estimated 560 US gallons (2,100 L) of 160 °F (70 °C) water per minute.

As this Osprey heads for impact with the water below, I think of the impact we have had on them. This species will forever be tied to the conservation movement that started in the 1950's. Think or even better read about Rachel Carson and her role in wildlife conservation, if your unfamiliar with it.
For instance did you know she was only 57 when she passed and is considered by many to be the mother of our modern day conservation efforts? "Silent Spring" Rachels 1962 book was an awakening to the world of wildlife conservation and an amazing gift to all of us who love it....
Once an Osprey learns how to fish, pretty much all they need is a healthy habitat and fish. In the northern parts of the US this species is migratory, arriving as early as late March with most birds usually heading south again by October, although we often still see a few staying into November in warmer years.
By the 1950's and 60's the Osprey's numbers and breeding success (along with many other species) was being severely impacted by synthetic pesticides and it was discovered that one called DDT was the main culprit. It built up in their systems and inhibited the absorption of calcium, which caused the thinning of the it's eggs.
For younger viewers and birders who may be unfamiliar with this, there is some wonderful information available at this link for further reading.
This is another image I completed on my recent trip to Kartchner Caverns. I had been collecting data with three different combinations of camera and telescope, but just could not get the signal to noise ratio I wanted. After this last run, I had a ton of data, over 100 subframes in each channel of LRGB. With so many subs, I skipped the calibration frames and just stacked them all. Pretty much all the flaws were rejected by the algorithm, and it came out pretty clean. A little cleanup with GraExpert, plus normal processing in PI. Description below is stolen from APOD.
In this celestial abstract art composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines just above the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that abstract painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in a setting like this one -- a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-years across.

My first reaction to this abundance of foam floating down the river was to think there had been some sort of toxic spill. Turns out there was a more benign explanation. At this point in the season tons of organic materials are being washed into the river. As they decay they produce surfactants which reduce the water's natural surface tension, and this allows for an easy absorption of large quantities of air into the water. Just above the site of this shot is a small set of falls which are roiling at quite a pace thanks to all the rain. End result: foam.
With the absorption of the Western Maryland into Chessie System most of the Western Maryland mainline west of Big Pool, MD was abandoned. This freed up WM power and it began to show up on the B&O. Here a WM AB set of F units brings a westbound across the Potomac River.
Just around the curve is San Luis Obispo train station, looking north west. The hills are Cerro San Luis, aka, Madonna Mountain (L), and Bishop Peak (R), two of the Nine Sisters, a chain of ancient volcanic peaks, which stretch from San Luis Obispo to Morro Bay. The bike is my vintage 1990 Diamondback Apex, a high-end bike at the time when front shocks were first coming out on MTB. $525 was a lot to spend back then but with 21 gears I could climb just about any hill. Grade and terrain were the only limiting factors. Grinding up a hill in lowest gear and coming down in control gets in your blood if you’re into that sort of exercise. Today’s 3 to $6000 bikes, some electric, give riders opportunities and comfort that this bike never had. This bike and I once muscled up to 11,000 feet near Mammoth Lakes. The up is hard enough but coming down on the rocky 4 x 4 Road is tough on the forearms, the eyeballs and the body because there’s no shock absorption like modern dual suspension bikes. Another memorable ride was 5,700 foot Mt. Wilson in the San Gabriel Mountains of Southern California. These days this bike sees more mild rides around town with occasional off roading. If this bike could talk, the stories it could tell… happy trails🚵
Casa Cavassa, a refined Renaissance residence in the historic heart of Saluzzo, was transformed in the late 15th century by Marquis Michele Antonio di Saluzzo into an elegant urban palace blending medieval structure with Renaissance elegance. Today home to the Civic Museum Casa Cavassa, it preserves original frescoes, stuccoes, and period furnishings, offering a rare glimpse into the domestic life and artistic tastes of the noble elite in the Marquisate of Saluzzo. Its harmonious courtyard and richly decorated interiors reflect the cultural flourishing of this independent Piedmontese state before its absorption into the Duchy of Savoy.
The rising Full Moon of September 9, 2022, the Harvest Moon for 2022, coming up over a rolling harvested prairie field near home in southern Alberta, on a very clear evening.
This is a composite of 11 exposures blended with Lighter Color mode onto the base layer exposure of the Moon just coming up and the sky and ground. The subsequent exposures were shot at increasingly shorter shutter speeds to preserve the colour and brightness of the Moon's disk (ie. exposing for the Moon not the sky or ground). Shot at 1 minute intervals, but exposures taken every 3 minutes were selected for the composite except at the start when atmospheric refraction makes the Moon rise faster than it does later in the sequence.
All were shot with the Canon R5 and RF70-200mm lens at 200mm.
Diese schöne Hibiskusblüte fotografierte ich im Botanischen Garten in Erlangen. Dabei wählte ich wieder eine halboffene seitliche Perspektive mit Gegenlichtaufnahme. Als Hintergrund nahm ich den blauen Himmel mit Wolken, um ein harmonisches Gesamtbild zu bekommen. Viel Spaß beim betrachten.
This beautiful hibiscus flower I photographed at the Botanical Garden in Erlangen. Here I chose again a semi-lateral view with counter-light absorption. As background, I took the blue sky with clouds to create a harmonious overall picture. Enjoy the view.
这个美丽的芙蓉花拍在植物园中的根。在这里，我选择了一个半侧面与反光吸收。作为背景，我在蔚蓝的天空与云彩，以创造一个和谐的大局。欣赏。
هذه الزهور الجميلة خبازى الأول صورت في حديقة النباتات الملكية. اخترت هنا مرة أخرى شبه الأفقي مضادة بهدف امتصاص الضوء. معلومات أساسية ، وأخذت السماء الزرقاء والسحب مع متناغم لخلق صورة عامة. يتمتع الرأي.
There are many different types of figs, from dark purple to green and slightly purple.We have four fig trees, one of which is over 8 metres tall and unfortunately only bears false fruit. The smaller ones bear fruit at different times, so that we can harvest new fruit every month...Figs are very healthy
..Vitamin A (retinol) is good for the skin and mucous membranes as well as the eyesight of our eyes.
Vitamins B1, B2 and B6 regulate the metabolism and are important for the nerves.
The absorption of folic acid is a prerequisite for cell division and blood formation.
Biotin (vitamin B7) supports healthy skin, healthy hair and strong fingernails.
A high magnesium content promotes cell regeneration and energy balance.
It also contains potassium, phosphorus and iron. Potassium can help to normalize blood pressure. Iron is needed for blood formation.

This is Virje waterfall, near Bovec, Slovenia. The waterfall itself is lovely, if not very large, but the pond is incredible! Of a deep, emerald green, absolutely transparent. One could think that the Lady of the Lake was going to appear at any moment.
I'm not sure why it is so green Possibly, the yelowish color of the rocks at the bottom, combined with the clear water and the laws of light absorption, result in those wonderful tones.
To reach it, go to Bovec and then west to Plužna. A bit pass Plužna there is a parking not 5 min from the waterfall. We tried to get there by a road that goes through "Golf Bovec", but the people at the club entrance refused to let us pass (!), or park there and walk the rest of the way. There was a van with a German family in front of us and they were, naturaly, quite pissed with the golf club people. Anyway, the way through Plužna is much more convenient.

In the 2nd Anniversary of the loss of the man I love the most,
my Papà Silvio.
"Addio Signor Maestro" video turned by Stefano Wolf mainly with some of my old archive photos, then put apart and published with added piano music "We'll Meet Again" kindly put at disposal by author composer and pianist Jeremy Blacke, on the day my Daddy sadly left : youtu.be/gND-a_3QXyQ
My Dad for his books and historical researches has also been a documentaristic photographer.
Anche i fiori stanno piangendo
Non passa mai, papà...
Do you see me
Can you hear me
Are you smiling
or are you anguished
Now that you are in the light,
can you face how miserable we are...
All the Love you left down here...
...And I'm drowning in Love for you
Watching over, please, save me
