Astronomical Spectroscope displayed during National Science Day 26 at Raman Research institute in Bengaluru.
An astronomical spectroscope splits light from celestial objects into its spectrum to analyze their physical properties. By studying emission or absorption lines in the spectrum, astronomers determine a star’s chemical composition, temperature, density, mass, distance, and radial velocity.
Many species of mushrooms seemingly appear overnight, growing or expanding rapidly. In reality all species of mushrooms take several days to form primordial mushroom fruit bodies, though they do expand rapidly by the absorption of fluids.

CN L550 switches the west end of Aldershot on a muggy, hazy Sunday morning with a trio of GP9Rm's bracketing recent arrival GMTX 2254. CN has leased a number of GP38-2's from GMTX, in part to assist with the absorption of the GEXR (Guelph Sub.) and the SOR back into the CN network in the next couple of months.
The Atacama desert provides one of the purest starry skies on Earth. The sky is so clear and dark that rare phenomena can actually be observed. For example, in this picture taken from Cerro Paranal Observatory (home to the Very Large Telescope), we clearly see two separate sources of natural light:
- The Zodiacal light: a white tilted cone of light which comes from the diffusion of sunlight by dust particles located in space (within the inner orbital plane of the solar system).
- The Airglow: an orange/red veil of light covering almost the whole sky. Airglow is a chemiluminescence process that results in the production of light after UV sunlight interacted with molecules/atoms of the upper layers of the atmosphere. The absorption of UV light by the atmosphere is only temporal and ends by remitting energy under the form of visible light.
This view was taken from Paranal Residencia located about 2 kilometers away from Cerro Paranal which you can spot in the middle of the image: a flat mount on top of which four tiny rectangular domes are installed: they are the four telescopes forming one of the most powerful astronomical infrastructure of the world: the Very Large Telescope or VLT.

Paul Cézanne -
Still-life with apples and peaches [1905] -
Washington NGA AN 1959.15.1
"The eye must grasp, bring things together," Cézanne said, "The brain will give it shape." In a still life, where the artist also creates the world he paints, each object, each placement, each viewpoint represents a decision. Cézanne painted and repainted the objects pictured here many times. The table, patterned cloth, and flowered pitcher were all props he kept in his studio. Every different arrangement was a new exploration of forms and their relationships.
Here the table tilts unexpectedly, defying traditional rules of perspective. Similarly, we see the pitcher in profile but are also allowed a look down into it. Paradoxically, it is Cézanne's fidelity to what he saw that accounts for this "denial" of logic and three–dimensional space. It is not so much that he is deliberately flattening space. Rather he is concentrating on the objects themselves instead of the perspectival scheme—the "box of air"—in which they exist. Cézanne worked slowly and deliberately. Over the course of days, he would move his easel, painting different objects—or even the same one—from different points of view. Each time, he painted what he saw. It was his absorption in the process of painting that pushed his work toward abstraction.
Alias: Syphon
Real Name: Vissia Burrows
Gender: Female
Allegiance: Villain
Backstory: The mother of Detonator, and Turbokiller, she's also the arch nemesis of the first Burnout. She starts out as a lowlife thief, knocking over small grocery stores. As time went on, she decided to do bigger crimes. Eventually, she ended up joining Mayhem. Years later, she would have Naomi, who would become the psychotic Turbokiller, along with Nathan, who would become the destructive force known as Detonator.
Edit: So I decided to go with Multi Sharp's idea. While her head definitely does lean itself towards sound, the energy absorption is similar to Turbokiller syphoning energy to survive, and the redirection could be seen as somewhat explosive depending on the size/scale. Also, I do already have a really cool sound manipulator in Siren (I mean it's just one of her many cool abilities.)
Status: Alive and at large. Works for Mayhem.
Galactic Archaeology in the Triangulum System (M33) [M33 DAS-2]

Triangulum is a dwarf spiral galaxy, believed to be the largest satellite of Andromeda (M31). Due to its morphological characteristics, it can be classified as a low surface brightness (LSB) galaxy, visible at a low inclination angle.
Although considered in scientific literature to be a galaxy free of disturbances due to tidal interactions, upon closer analysis, it exhibits an unmistakable morphology attributable to past events.
According to some less than convincing interpretations, M33 experienced a close passage to M31. This event, dating back between 6 and 8 billion years, is attributed to the evident distortions in the outer arms, particularly the northern one, as well as the subtraction of its family of dwarf satellite galaxies and a significant number of globular clusters.
Kinematic considerations make this scenario unlikely. According to recent models and evidence, Triangulum is instead falling for the first time into the gravitational pull of M31 and, more generally, the Local Group, with little likelihood of future interaction and merger.
The signs of interaction exhibited, demonstrated beyond doubt in this new analysis, are therefore attributable to past minor merger events involving the capture, disruption, and absorption of some of its gas-rich satellites, with evidence of an outflow of ionized hydrogen. The presence of at least three ultrafaint satellite galaxies (Andromeda XXII, Pisces VII, and Triangulum IV) supports this hypothesis.
Note how some of the detected structures perfectly superimpose on the asymmetric neutral gas halo, which has been known for some time.
We have been covered by 15.5 inches (39 cm) of dense, heavy, wet snow. I was surprised to see the inner layers had a bit of turquoise glow. We don't see this very often, our snow is typically loose and grainy.
Blue-green colors in the 'shadows' of snow is caused by the absorption of both red and yellow light, leaving light at the blue and green end of the visible light spectrum. This doesn't usually happen in 'loose' snow, but happens more often in ice and icebergs. This snow is particularly dense.
A better explanation here.
Looks like he is about to loose the viewfinder eye piece.
Ever wondered...Why are most of the telephoto lenses used
in sports and other tele-photography white or light grey?
well it's probably a Canon L series lens.
Some say it helps to reduce heat absorption, and hence heat expansion of the structure of the lens -
But more likely - I think brand recognition is about 1/2 the truth (less heat absorption being the other 1/2).
Nikon has been using black for their telephoto lenses for years. I have never heard any complaint about heat absorption or build-up.
The longest telephoto AF-S Nikkors are available in light grey via special order and Minolta and Olympus have or have had light coloured telephotos while Pentax has a metallic finish on theirs.

Penn Central E40 electric #4977 poses in the yard at Morrisville, PA, January 23, 1976. Conrail is less than four months away from taking over the Penn Central's rail operations and thus inheriting this and it's unwanted brothers which originally came from the New Haven Railroad upon the NH's absorption into PC. The E40's were originally classed EP5s by the New Haven when they arrived in 1955 from GE. They were intended for high speed passenger operation between New York City and New Haven, CT. Teething problems from the outset were solved within a year of arrival from GE-mainly the large screened filters on the carbody sides which helped in cooling the electric motors along with the automatic blowers. What caused their downfall was the McGinnis/Alpert regime's greatly reduced maintenance on these and almost all other locomotives the NH had. The damage had been done and unfortunately they fared no better under Penn Central ownership. By the early '70s all were out of service and one even scrapped but someone at PC felt the road should rebuild three of them for freight service and so the 4977 became one of the lucky three to survive into Conrail ownership. Sadly the three never turned a revenue wheel for Conrail as that road had a lot more on it's plate to deal with than three oddball electrics of questionable reliability. The final three E40s were scrapped in 1979. This is an Ektachrome 6x6 color transparency originally marketed as a Super Slide. The film frame was mounted in a cardboard mount which allowed for projection with the proper slide carrier mounted to a projector. Unfortunately this also allowed for the image to be scratched badly.

Poem.
The mercury greys, the tree-lined ebony silhouettes, deep indigo and silver-coated marbling, gleaming, beaming off the cloud-reflected bay-
Dazzles and spell-binds.
That precious God-given ambience of early dawn blinds us but etches blurred images of heavenly proportions to our senses.
The mesmerising light, the near-silent water’s edge only broken by the lilting call of the oyster-catcher or the muffled comments of stirring sailors aboard their dreamy yachts.
These familiar sounds, the salt-laden odours of a near-calm bay and the silent, gentle absorption of the sun’s rays rouses and energises a myriad of life-forms to a glorious new day.
To witness this scene is pure bliss.
To hear, feel and sense it, is almost indescribable.
Sometimes it happens to notice the unusual and magic of this dream world. The shadow has no object. The observer is absorbed in the shadow itself. This is definitely something!
1. Taking pictures a tool (camera), not a photographer.
2. The choice of tool limits the possibilities.
3. Experience allows him (instrument) less and less to limit their capabilities.
4. The ability to see is given only when the observer allows ...
5. The moment of observation is the real find ...
6. Training and mastering it defies. Training leads to poor imitations of the original.
7. Often the result should ripen, like wine. Although time is the understanding of the mind, therefore it is very speculative.
8. The meaning of all this is the process!
9. Let it be!

Multiple curtains of aurora appear along the curving arc of the auroral oval over the boreal forest. This is looking just a little east of due north from the second floor deck of the Churchill Northern Studies Centre, Churchill, Manitoba. Polaris is just left of top centre, with the Big Dipper at right of top centre. A meteor streaks to the left of Polaris. Vega is at lower left as a circumpolar star low in the north. The curtains appear more yellow toward the horizon due to atmospheric absorption. The curtains display the classic green tint with red upper fringes, both from transitions in oxygen.
This is how the Lights usually begin from this latitude under the auroral oval. They will then move up and south from this formation to cover the sky.
This is a 20-second exposure at f/2.8 with the 15mm full-frame fish-eye and Canon 6D at ISO 3200.
The rising Full Moon of June, dubbed the “Strawberry Moon” in the media, as seen rising over a prairie pond in southern Alberta, on June 9, 2017. At right, the glitter path from the Moon also combines on the water.
This illustrates the effect of the Moon brightening and becoming less red/yellow as it rises into clearer air above the horizon, with less atmospheric absorption of the short wavelengths.
This is a composite stack, obviously, of 15 exposures, selected to be about 2.5 minutes apart, from a time-lapse sequence of 1100 frames, with images taken at two second intervals. Shot with the Canon 6D and 200mm lens.
Just your average cryogenic superconductors, partially buried underneath the regolith for thermal isolation (and shock absorption in case of a catastrophic containment field failure, though no one will ever official admit to that).
This could be a circular set of 8 but angling the death star sphere in the center would make less sense in that case, and it's more interesting to not go for too much symmetry.

Exec Line, Æ-50 "Hard Case"
The Hard Case was developed to give the Æ-50 a more comfortable and easy to use platform. When it comes to engaging wood apes or the like, accuracy and speed is key. The stock incorporates a sophisticated recoil absorption system to make the strong .50 AE recoil more manageable. Unfortunately this system necessitates that the spent casings be ejected from the top. The front end of the kit gives the Æ-50 a muzzle brake to cut down on recoil. A high end, 1,000 lumen flashlight has been built in so you can blind the dirty primates while you blast away. A RDC-2 is included with the package to supplement the iron sights.

Inspiration comes from everywhere; anywhere. Just over a year ago while engaged in a fateful demolition of a fence Mary Radike Smith posted a picture from a project whose subject was "Home Archeology".
Lamenting the state of the weather, just the other day, Richard Harvey was tossing about the notion of the indoor sport of the still life. Obtuse as it may seem, back in January last year I was waiting for a sonographer and musing about my binoculars. Lo, and behold, what tied this altogether was an almost perfect alignment of absolutely nothing!
Actually, it's probably the weather — about which we all complain, yet do nothing. Six degrees celsius in the UK, minus 12⁰F in the USA and 333⁰K warmer in my garden, ahead of a forecast 30⁰Rø next week, has induced certain responses. Mine was to get around to my bit of Home Archaeology: a pile of stuff dug out of my soil.
Far be it from me to fling about nasturtiums on the former residents of The Estate. But I do wonder — with all of the broken bottles, crockery, and so on in the ground — whether they liked a drink, were just a bit clumsy, or a bit of both; maybe one following the other? Importantly, I had to wait this long to ask these questions because, in this season, the Sun was positioned, just so, as to enlighten this pile.
That mauve coloured object has my attention. It's like a backyard geochronometer. There was a time when small amounts of iron would give a green-cast to clear glass. Someone discovered that adding manganese in its bivalent state would counter the influence of the iron impurity. That process commenced around 1880 and was discontinued about 1915 when the manganese was replaced by selenium; or so the internet says. Roll forward until I dug up this broken neck of a soda bottle. No longer clear, the long exposure of that glass to UV light has oxidised the bivalent manganese to its trivalent or tetravalent state resulting in the colour change. Now we know. If they were a bunch of drunks, it was likely over a century ago, and I have the still life to prove it.

Name: Stefan Nicholas Rost Akerman
Villain’s name: Biocide
Age: mid-20’s
Bio: Son of a Dutch diplomat and a Swedish biological scientist, Stefan was raised in the Swiss Alps but moved to America at 6. He grew up with no friends and was always obsessed with plants and life. He had high hopes of making death and decay become life and resurrection once more. But some of experiments proved to be a failure, and did not turn out well for anyone. It was simply expensive and no one approved of what he did. Stefan turned to being a eco-terrorist after enhancing himself with more powers, but he only did that for months after Paradox Force faced him multiple times.
His long standing history with Paradox Force (mostly Grey Cop) led him devoting his time to become a mercenary. Until that, he was re hired by Hendrix and co, with thoughts of being a villain again...
Powers and abilities: Poison manipulation, generation and absorption, acid blasts/generation, create biological bombs, control plants, some pheromes, secrete biological and etc.
Weaknesses: Powers can be contained, immune against those who resist poison and toxins, control over acid that may destroy things he doesn’t intend to, some acids are limited to different kinds, bases can be used against him, rendering him neutralised and powerless. Plant life requires water and solar energy, people who are immune to his poison. Failure at his own experiments causes him to be very angry. The suit can run out of battery sometimes.
Equipment: Bio-suit with haredened armour, has solar absorption functions through battery. Biological, plant related bombs/weapons, usually carries two guns
Personality: Cunning, malicious, cruel, disdain, cold, bitter.

The mysterious planet Cyano orbits deep inside the alt process belt. It consists entirely of ferric ammonium citrate. Absorption of UV radiation by its atmosphere of gaseous potassium ferricyanide results in an enormous electron migration in the planetary crystalline lattice thereby generating a super massive magnetosphere.

A real live Australian Water Dragon (Physignathus lesueurii) basking at dusk on a city park red mood light, presumably to either get a nice warm glow to look hot and/or to stay warm. :) I especially like the back leg stretch and the skin's rich absorption of red colour from the light. The dragon also looks very happy with its achievements and position and made no attempt to move when I carefully approached to photograph. The really cool thing was the light changed colour every so often and so did the dragon's colour. By way of example, please see the photo below.
Thanks for stopping by. Appreciate your comments. :)

Beziehungen bestimmen unser Leben in allen Bereichen. Bei Gebäuden, die für Ausstellungen geschaffen werden, ergeben sich gleich mehrere Beziehungen.
Nichts und Niemand kann für sich alleine bestehen. Ein Architekt setzt seine Gebäude in einen räumliche und kulturelle Beziehung, man könnte auch Kontext sagen. Ein Kurator setzt ein Kunstwerk in Beziehung zum Raum und anderen Kunstwerken. Der Betrachter eröffnet eine neue Beziehung durch Wahrnehmung des Vorangegangenen und bringt das Kunstwerk in Beziehung zu seinem Leben und seinen Erfahrungen und in eine Kommunikation mit sich selbst und anderen Menschen zu denen er in verschiedenen Beziehungen steht und diese geben es vielleicht weiter, unendliche Reflexionen und Absorbtionen mit all ihren Veränderungen ... und wir Fotografen treten natürlich auch, jeder auf seinen Weise zu seinen Motiven in eine Beziehung ... Gedankenspiele ... ;-) ...
Relationships determine our lives in all areas. In the case of buildings created for exhibitions, several relationships arise at once.
Nothing and no one can exist on its own. An architect places his buildings in a spatial and cultural relationship, one could also say context. A curator puts a work of art in relation to space and other works of art. The viewer opens a new relationship by perceiving what has gone before and brings the artwork into relationship with his life and experiences and into a communication with himself and other people with whom he is in different relationships and they perhaps pass it on, infinite reflections and absorptions with all their changes ... and we photographers of course also enter, each in his own way to his subjects in a relationship ... Mind games ... ;-) ...

ABOUT THE ARTIST
Chance Nkosi Gomez known initiated by H.H Swami Jyotirmayanda as Sri Govinda walks an integral yogic path in which photography is the primary creative field of expression. The medium was introduced during sophomore year of high school by educator Dr. Devin Marsh of Robert Morgan Educational Center. Coming into alignment with light, its nature and articulating the camera was the focus during that time. Thereafter while completing a Photographic Technology Degree, the realization of what made an image “striking” came to the foreground of the inner dialogue. These college years brought forth major absorption and reflection as an apprentice to photographer and educator Tony A. Chirinos of Miami Dade College. The process of working towards a singular idea of interest and thus building a series became the heading from here on while the camera aided in cultivating an adherence to the present moment. The viewfinder resembles a doorway to the unified field of consciousness in which line, shape, form, color, value, texture all dissolve. It is here that the yogi is reminded of sat-chit-ananda (the supreme reality as all-pervading; pure consciousness). As of May 2024 Govinda has completed his 300hr yoga teacher training program at Sattva Yoga Academy studying from Master Yogi Anand Mehrotra in Rishikesh, India, Himalayas. This has strengthened his personal Sadhana and allows one to carry and share ancient Vedic Technology leading others in ultimately directing their intellect to bloom into intuition. As awareness and self-realization grows so does the imagery that is all at once divine in the mastery of capturing and controlling light. Over the last seven years he has self-published six photographic books, Follow me i’ll be right behind you (2017), Sonata - Minimal Study (2018), Birds Singing Lies (2018), Rwanda (2019), Where does the body begin? (2019) & Swayam Jyotis (2023). Currently, Govinda is employed at the Leica Store Miami as a camera specialist and starting his journey as a practitioner of yoga ॐ

Macro photography can be quite absorbing. Sort of like zen. Or flow, which is characterized by "complete absorption in what one does and the almost complete loss of sense of space and time". Flow is an innately positive experience; it is known to "produce intense feelings of enjoyment". Hence macrohappy 😀🌸
This 2004 montage shows three clusters of bright, young stars in X-ray (blue) and infrared (green) light that lie in the direction of the center of the Galaxy. Like many stars in the disk of the Galaxy, they are difficult, if not impossible, to see with an optical telescope because of interstellar dust that blocks the visible light.
Infrared and X-ray data provide evidence for a large amount of dust and gas along the line of sight to the cluster, DB01-42. Invisible to optical telescopes, it is located near the Galactic Center, about 26,000 light years from Earth. Most of the stars in the image produce infrared radiation from their surfaces which have temperatures of several thousand degrees Celsius. The X-radiation from the two bright X-ray sources near the center of the cluster requires gas with temperatures of millions of degrees.
Such extremely hot gas may be due to the collision of stellar winds from two closely orbiting stars. The two bright X-ray sources in the image are likely close binary stars with high-speed stellar winds. The diffuse X-ray glow could be caused by the combined heating of gas in the cluster by winds from many stars.
The light from the stars in the two clusters, DB00-58 and DB00-6 show much less X-ray and infrared absorption. This lower absorption, which still blocks much of the visible light, indicates that these star clusters are not in the Galactic Center, but are foreground objects. The way in which the X-rays are produced in these clusters is likely to be similar to DB01-42.

EP20 is equipped by the 3 power bogies produced by the NEVZ itself and presumably developed on the base of the FLEXX Power 140 RU locomotive bogie designed by Bombardie.
The bogie suspension system is consisted of coil primary suspension with a one-sided, wear-free wheelset guidance, and flexicoil secondary suspension (the support of the carbody on the bogie) realised by wear free secondary coil springs equipeed with anti-hunting and anti-rocking dampers; according to flexicoil principle the bogie on the coils can be freely deflected into vertical and horizontal directions. Tractive forces from bogie to locomotive are transferred via traction rods connected to a low lying connection at the bogie pivot centre. Mechanical braking is realized by the wheel mounted disc brakes. Electric braking is either up to 4.5MW rheostatic braking via roof mounted resistors, or up to 7.2MW regenerative braking.
The EP20 (ЭП20) is a type of 6 axle Bo'Bo'Bo' dual-system electric passenger locomotive being built from 2011 y for Russian Railways by the Novocherkassk Electric Locomotive Plant (as a part of the Transmashholding), the main electric locomotive developer and producer in Soviet Union and Russia. EP20 was designed to replace of failed EP10 project by TRTrans, a joint venture between Transmashholding and Alstom by French, Belgian, and Russia based engineers to 2008 y. It is able to haul 24 coaches at 160 km/h or 17 coaches at 200 km/h and operate both on the DC and AC electrified tracks (3kV DC or 25 kV 50 Hz AC). Possibly for a first time for Russian locomotives, the cab design includes special progressive deformation steel cage for impact absorption. Due to extremal quantity of foreign components and thier high price a year production is not so big and now built 77 from 200 of ordered.
Some specifications:
Loco weight -135 t
Power output: continuous - 6600 kW /hourly - 7200 kW,
Tractive effort: 350 kN (0-74 km/h) 115 kN at 200 km/h
Motors: Bogie suspended six pole 1.2 MW (1,600 hp) asynchronous DTA-1200A with six IGBT traction converters
Transmission: Bogie mounted traction motors, via gear to hollow shaft drive, with flexible couplings
Loco brake:Rheostatic 4500 kW (DC)/ 3200 kW (AC), regenerative 6000 kW, electropneumatic wheel disc.

The Yonghe Temple, also known as the Yonghe Lamasery, or popularly as the Lama Temple, is a temple and monastery of the Gelug school of Tibetan Buddhism located on 12 Yonghegong Street, Dongcheng District, Beijing, China. The building and artwork of the temple is a combination of Han Chinese and Tibetan styles, established in 1694.
The colourful but obscure area in the Cepheus Milky Way that contains the Lion Nebula (at bottom), a region emitting both red Hydrogen-alpha light and cyan Oxygen III light. It is a nebula that only recently became popular as an astrophoto target, perhaps because of its new nickname and from the use of narrowband filters to bring it out. It is not in the popular Messier, NGC or IC catalogues but is officially labeled as Sharpless 2-132. Meanwhile at top, the brightest nebula is the even more obscure Sharpless 2-135, alongside a very faint band of nebulosity that might not have a catalogue number — I couldn't find one!
The nebulosity at top is a deeper red than the Lion Nebula, as the top area of sky contains more dark dust absorbing and reddening the nebulosity and also decreasing the star density and yellowing the sky compared to the richer, brighter and bluer region at bottom to the south around the Lion.
There is a very small (like a fuzzy red star) planetary nebula just right of centre called the Little Ring Nebula, or M2-51, from the Minkowski catalogue. Another tiny planetary in the extreme lower left corner is Abell 79. The field of view here is 5° by 3.3°, with north up.
The star at upper left is the famous variable and double star Delta Cephei. The yellow star at right is Zeta Cephei.

- A stack of 16 x 16-minute exposures through an IDAS NBX dual ultra-narrowband filter at ISO 1600. This set was shot on night #2 as there was not enough time to shoot it on the same night at the other sets.
The clear filter set contributes the sky background and natural star colours. The NB1 filter set contributes most of the red H-alpha component, while the "extreme" NBX filter contributes mostly the cyan OIII emission which the Lion Nebula has in abundance, somewhat unusually for an emission nebula.
All stacked, aligned, merged and masked in Photoshop 2021. Luminosity masks with Lumenzia helped bring out the faint nebulosity.
Taken from home. Autoguided with the MGEN3 autoguider applying a dithering move between each exposure average out thermal noise when aligning and stacking. No LENR or dark frames were employed on this frosty night! At one point late on night 2 the little guidescope frosted over as the guide star was lost. Hair dryer to the rescue!
This is for Stars N' Heroes' Super-Villain Contest.
Left-Right:
BIllard Wrecker: Brawn
Powers: Super-Strength and Durability
Weaknesses: Cybernetic implants have been used to make him stronger, however they keep destroying his brain leaving him to have the mind of a 3 year old.
Backstory: The Wrecker triplets were all going to fail in life. They're parents were crack-addicted alcoholics.
--------------------------------------------
William Wrecker: Brainpower
Powers: Super-Intelligent cyborg.
Weaknesses: No durability or Strength whatsoever.
Backstory: William Wrecker was the only smart one in his whole family. He tried his best to get a good job and resume, instead he decided crime was easier. he and his brothers went to get cybernetic implants and William became the Super-Villain, Brainpower.
-------------------------------------------
Duke Wrecker: Suckapunch
Powers: Super-Strength, Durability, and Power Absorption
Weaknesses: Slow on speed and relies on brute force.
Backstory: Superhero geek that never had much in life. He soon got Cybernetic implants that messed with his brain causing him to become a crazed murder.
West Midlands Travel Leyland Fleetline / East Lancs 6721 was the first of this batch of 40 to arrive in March 1977, the final order placed by Coventry Transport prior to its absorption into West Midlands PTE in 1974. Seen here in its home city 13 years later, series withdrawals of the batch commenced the previous year, but several others lasted long enough to receive the later version of fleet livery.

Let’s talk about colour. Snowflakes are not flat, they have volume. That volume allows for air pockets to be trapped in the ice. Given the right thickness of the “bubble” and/or the right thickness of the ice on either side of it, something magical can happen.
Before I continue my rambles, however: the second edition of my macro photography book is out. The publisher just restocked their North American supply, which can be ordered direct: www.routledge.com/Macro-Photography-The-Universe-at-Our-F... - they gave me a special code for 20% off if ordered direct: 25SMA4
Snowflakes don’t possess colour the way we normally see colour: absorption and reflection. A red car is red because it absorbs all colours except red. A snowflake, however, behaves more like a soap bubble, a spot of oil on the ground, or the wings of the Madagascan Sunset Moth, among others. Here we’re talking about “thin film interference”. The colours are created from light interfering with itself inside the crystal through multiple air/ice boundaries, and thickness matters.
There’s fancy calculators and physics for this ( www.sciencecalculators.org/optics/thin-films/ ) but the basics are pretty easy to understand. The speed of light isn’t constant, it changes based on what it is traveling through. Fastest in a vacuum, slower in air, slower further in ice. When light enters ice, it slows down and the trajectory changes. However, not all light enters the ice – a good portion is reflected off the surface. This reflected light never slows down. That’s our baseline.
The light that enters the ice? Some of it will reflect off the inner boundary – where the air pocket is. This light will then travel back up through the ice, and into the air once more. However, it is now “out of sync” with the light that never entered the ice. It was moving slower for a very brief period of time. What happens when the ice is so thin that the resulting beams of light are within a wavelength of each-other? While being out of sync? They interfere with one another, both constructively and destructively.
This means that “white” light (all the colours) will be transformed. How thick the ice is will determine the resulting colours that you see (there’s a chart here that references colours and thickness: soapbubble.fandom.com/wiki/Color_and_Film_Thickness ). Just like any waves (sound, water, light), some interference will cancel things out (destructive), and some will amplify (constructive). This is where the colour in snowflakes come from; the light is shaped by the snowflake itself.
I’ve seen thin film interference everywhere from a cup of Turkish coffee to the meniscus formed around the lid of fountain pen ink. Ever see “Newton’s Rings?” - It’s everywhere if you’re paying attention. Not all snowflakes have the right balance of features to produce it, but when it shows up to the party, it’s always the first thing you notice.
Delta 400.
A black and white film simulation using DxO Film Pack software.
Delta 400 uses the "core-shell crystal" tabular technology known as T-grain which is different from a conventional-grain film in the way that the film’s silver content is distributed. T-grain films have flat crystals whereas conventional-grain films (Tri-X, HP5,) have round crystals. The flatness of the crystal allows better light absorption. Theoretically, a T-grain film should provide sharper images when compared to a conventional-grain film. The Delta 400 can be used between 200 and 3200 ISO. It's one of the more flexible films for a wide range of uses in analogue photography.
