About creativity.

They write (amongst many other things): It is the ability to "think outside the box" ! I ask: WHAT BOX???? LOL

I must admit that as a 'creative',

1, being a night-person, my 'best' ideas mostly come after midnight!

2, it is an urge, not a choice... and

3, ... as soon as I have 'problems', however small, with client, family, health... the first thing to GO is: my creativity! So please, tee hee, do not upset me, he?

Characteristics of the creative personality:

Creative individuals have a great deal of energy, but they are also often quiet and at rest.

Creative individuals tend to be smart, yet also naive at the same time.

Creative individuals have a combination of playfulness and discipline, or responsibility and irresponsibility.

Creative individuals alternate between imagination and fantasy at one end, and rooted sense of reality at the other.

Creative people seem to harbour opposite tendencies on the continuum between extroversion and introversion.

Creative individuals are also remarkable humble and proud at the same time.

Creative individuals to a certain extent escape rigid gender role stereotyping and have a tendency toward androgyny.

Generally, creative people are thought to be rebellious and independent.

Most creative persons are very passionate about their work, yet they can be extremely objective about it as well.

The openness and sensitivity of creative individuals often exposes them to suffering pain yet also a great deal of enjoyment.

I recognise myself COMPLETELY in this!

Take care, be safe!

Alt Photo Red Sensitivity B&W film

One from 2017 when I did my birds of Prey course. An intense stare from the Strix Aluco.

An owl's eyes are placed at the front of the head and have a field overlap of 50–70%, giving it better binocular vision than diurnal birds of prey (overlap 30–50%). The tawny owl's retina has about 56,000 light-sensitive rod cells per square millimetre (36 million per square inch); although earlier claims that it could see in the infrared part of the spectrum have been dismissed, it is still often said to have eyesight 10 to 100 times better than humans in low-light conditions. However, the experimental basis for this claim is probably inaccurate by at least a factor of 10. The owl's actual visual acuity is only slightly greater than that of humans, and any increased sensitivity is due to optical factors rather than to greater retinal sensitivity; both humans and owl have reached the limit of resolution for the retinas of terrestrial vertebrates.

Adaptations to night vision include the large size of the eye, its tubular shape, large numbers of closely packed retinal rods, and an absence of cone cells, since rod cells have superior light sensitivity. There are few coloured oil drops, which would reduce the light intensity. Unlike diurnal birds of prey, owls normally have only one fovea, and that is poorly developed except in daytime hunters like the short-eared owl.

I've spent the past few months working my way through a couple rolls of the new Fuji Acros II attempting to answer the questions I have about the film. Questions like, "How similar to the original Acros is it?" "What about it's reciprocity failure?" "Is it as fine of grain?" Then yesterday I compiled all those thoughts, images and notes and wrote something for Blue Moon Camera that is halfway between first impression and review. You can read it if you'd like at the Codex section of the Blue Moon Camera website. Suffice it to say, that for all intents and purposes, Acros II is as close to the original as you could ever want it to be. There is a slight change in contrast, a slight change in spectral sensitivity, it might actually be a little finer grained if that is even possible, and no change in terms of how it handles long exposures. This was a 30 minute exposure with only 1 extra stop of reciprocity compensation added.

So I am excited to have access to this film again (we just got a couple hundred rolls at the shop). I have been going back through pages of old b&w negatives over the last month on the hunt for any film stocks that weren't Tri-X and I was surprised by how much Acros I have shot over the years. I knew I liked the film, but had forgotten how much of it I have used. So now I am looking forward to using this second iteration of that excellent film. If only we could get Fuji to bring back Neopan 400 and 1600 now.

This was the shot that concluded my first experience of the Northern Lights, as seen at Hvalnes Lighthouse, Iceland.

A group of 5 of us had been on the road all day and had seen (in my opinion) one of the most amazing sunsets ever - panorama to follow. We were partly anticipating seeing the lights, but half resigned to calling it a night for some much needed sleep. Thankfully we checked outside one last time before bed.

I wasn't sure quite what to expect and to the eye, the 'lights' at first seemed like quite dull, linear white clouds. When photographed with a camera at relatively high sensitivity, the brightness and colours really popped out.

We saw the 'lights' on two more evenings, with the last evening being much brighter and more spectacular.

A present from Shannon!!!!;-))

These are the Fleeples Family and Fliola is the solist! They arrived lately from USA and they are staying at my home!

Shannon , my dear friend ,manager and creator of the Boogerellis ,send them to me as a present! www.flickr.com/photos/boogerelli_creations/

They are the loveliest company, cute and i love their characters...and even more Fliola is a violoncelist! I love cello! Well this is their performing night, in honor of Shannon!

The only problem was that i couldn't get a shot of them as good as Shannon's!

Thank you my dear for your sensitivity and care and tenderness! My love!!!!!!

Because of the eery shape of NGC 246 being a little like a human skull, it has now become commonly known as the Skull Nebula, and categorised by Sir Patrick Moore as Caldwell 56. The object is in fact a planetary nebula, the remnants of a failed star many years past. You’ll find this object in the constellation of Cetus, with it being roughly 1,600 light-years away from Earth.

This image represents only 24% of the cameras full frame, composed of luminance, red, green, blue, oxygen 3, and hydrogen alpha filtered colour channels. Thanks for having a look.

Some bright red holly berries... rendered nice and dark by the P30 lack of red sensitivity.

Nikon F6 + Tokina 100/2.8 macro + Ferrania P30.

Tintype with 3 months old collodion. Apparently, it already loses its sensitivity. Exposure 2,5 minutes at f11.

I think it goes without saying that I'm thankful for both Justine & Roger. I'm also thankful for Roger's loving, patient nature and the opportunity he's given Justine to experience all the joy that goes along with the human-canine bond. I believe that children who have loving, kind & positive relationships with animals grow up to have a certain sensitivity & sense of responsibility toward all living things. Justine truly loves & appreciates Roger...she feeds him, puts hair clips in his top knot and puts scarves on him. She has made up songs to sing to him & has sought him out for comfort she was sad. When she was not quite 2 I took her with me for the first time to drop Roger off at the groomer's. As the groomer took Roger's leash & led him to the back Justine stretched out her arms toward him & started crying, "Doggie, doggie!" and I had to explain to her that he would be coming back. Just last week, as soon as we got home from dropping him off at the groomer's, she said, "I miss Roger."

From a road trip back in 2017, this has long a bucket list destination. The Very Large Array on the Plains of San Agustin in South Central New Mexico, 50 miles west of Socorro, which also means "help" in Spanish.

Each of theses 28 massive telescopes is mounted on double parallel railroad tracks, so the radius and density of the array can be transformed to adjust the balance between its angular resolution and its surface brightness sensitivity.

You might remember the VLA from the 1997 Jodie Foster film, Contact, based on the novel of the same name by the late Carl Sagan.

It's kind of hard to realize how large these dishes really are until you get to see them up close, as evidenced by the person in standing behind the one closest to the camera.

I took my first image of the North America Nebula about a year ago. At that time I did not own a astro-modified camera and it was therefore a very though job to capture a descent image: flic.kr/p/xKk2ee

I bought a Hutech modified Canon 6D this year, but unfortunately it was damaged during my vacation in June. So I brought it to the Canon repair shop and, after waiting for almost a month I got my camera back. Free of charge and in mint condition...

To my dismay, it really was working perfectly - even in daylight conditions. No red color cast and no sign of increased red sensitivity! Obviously Canon had repaired away the astro-modification!

I returned it immediately to the repair shop and, after a lot of head scratching, it was sent to the main repair center of Canon Switzerland.

This week, I got my camera back. Of course I went outside the first clear night to make sure the astro-modification was back.

The logical target was the North America Nebula, as it is riding high in the sky at this time of the year and I got already some experience capturing it.

To my great relief the modification works perfectly again. So I probably am now the only guy in the world with camera, that was officially modified by Canon...

So I guess I am back in business. Thanks Canon!

Sometimes sensitive feelings and emotions are kept protected behind a hard exterior shell.

Despite that, it’s as if you can anticipate how people feel, even before they speak. And yet this would also be an excellent time to get some respite.

^_^

continuo a credere che siano le foto a trovare me e non io a dovermi piegare fino a terra per crearle, partorirle, dar loro consistenza.

continuo a credere che la cosa più importante sia:

tenere gli occhi aperti, anche quando sembrano chiusi a riposo.

e focalizzare l'attenzione su quello che ci sembra più vicino a noi.

le forzature, in ogni cosa, puzzano e disturbano la comunicazione.

già.

eppure ci sono così tanti 'fotografi' che forzano la mano e vengono acclamati.

evidentemente di fotografia non capisco proprio nulla.

International May 12th Awareness Day, also known as International ME/CFS Awareness Day is held every year to raise awareness of myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS), fibromyalgia, multiple chemical sensitivity, Gulf War syndrome and other chronic immunological and neurological diseases (CIND).

"È vegetariana o vegana solo una percentuale bassa della popolazione italiana (circa l’8%), ma l’ultimo rapporto dell’IPCC (Intergovernamental Panel on Climate Change) è molto chiaro nel sollecitare la popolazione mondiale “a favore di diete che implicano un minor uso di risorse.” Secondo il rapporto, un deciso cambiamento delle nostre diete in senso vegetariano potrebbe liberare milioni di chilometri quadrati dallo sfruttamento intensivo, riducendo le emissioni di CO2 fino a sei miliardi di tonnellate l’anno rispetto ai livelli attuali.

Ma chi sceglie di diventare vegetariano o vegano non lo fa per un astratto amore verso l’ambiente o per il futuro dell’umanità, quanto piuttosto per la raggiunta consapevolezza della simile sensibilità delle altre specie con la nostra, e del pari diritto alla vita. E’ del 1975 il saggio del filosofo Peter Singer “Liberazione animale”, un testo fondamentale dell’animalismo e dell’anti-specismo.

Ho fotografato alcuni miei amici vegetariani o vegani."

"Only a low percentage of the Italian population is vegetarian or vegan (about 8%), but the latest report by the IPCC (Intergovernmental Panel on Climate Change) is very clear in urging the world population" in favor of diets that involve less use of resources. " According to the report, a decisive change in our diets in the vegetarian sense could free millions of square kilometers from intensive exploitation, reducing CO2 emissions by up to six billion tons per year compared to current levels.

But those who choose to become vegetarian or vegan do not do so for an abstract love for the environment or for the future of humanity, but rather for the awareness of the similar sensitivity of the other species to ours, and of the equal right to life. 1975 was the essay by the philosopher Peter Singer "Animal Liberation", a fundamental text of animalism and anti-speciesism.

I photographed some of my vegetarian or vegan friends. "

Artist: Hans van Benthem

Place: Escher Museum (The former Winter Palace of Queen Mother Emma of the Netherlands)

The Hague

Biography

Born in 1965, The Hague, The Netherlands. Graduated from Royal Academy of Fine Art (KABK), The Hague

Works in China, Czech Republic and West-coast of Africa; lives in Amsterdam.

What inspires Hans van Bentem can be almost anything. A pop song, local skills in Jingdezhen or a character of the Muppet show, most likely Beaker, the long-suffering assistant who was named after a piece of laboratory tool.

Since 1990 Van Bentem has been producing large-scale sculptures. In 1990, 1992 and 1994 he received national grants (Fonds voor de Beeldende Kunsten (BKVB)).

Hans van Bentem is stimulated, once also by the punk movement, to tease our bourgeois habit to link art to a logical narrative. [As a boy the Dutch artist constructed do-it-yourself kits to take up the world.] Rough, fragile and smooth are his 2 meters high dildos made from Venetian glass in very soft light pink or light blue colors.

Hans van Bentem is not only playing with clichés but can be quite intelligent in displaying a strong sensitivity to the intended sites for his work. In his major exhibition, at the Gemeente Museum Den Haag (The Municipal Museum of The Hague), Hans van Bentem filled up six style rooms, ranging from an original Louis XV style chamber to a lacquer interior of a Japanese Room, this latter space used as a setting for an installation of his porcelain sculptures of various body parts on a ceramic bed of lotus flowers, stones and lumps of rock.

His 14 contemporary crystal sculptures that are in the collection and permanently on view in the Escher Museum in The Hague (a shark, a spider and a sea horse and other works) bear great testimony to their site-specific character. In this former Winterpalace of Queen mother Emma that was officially used by the Royal family until the 1990’s, the crystal sculptures incorporate allusions both to the history of the building and to the gifted artist M.C. Escher.

NOTE: Ranked #176 in interestingness (on 2007-10-11). Thanx to everyone for their support!!

NOTE 2: I know that I seem like an HDR freak (which I AM), but this is NOT HDR btw...!! It's mere playing around with RAW format

While cruising doing some mashaweer, I stopped by to take this long shot (30 seconds exposure).

I hanged my Gorillapod SLR on the metal fence and did my thing. Using this toy turns anything (repeat: anything) as a tripod!! A true life saver.

Seconds later, I was surrounded with some low ranked policemen (3asaker). But I was smart. Before going there and while I was parking the car a few meters away, there was a soll (a higher ranked policeman) that I asked for his permission because of the sensitivity of the location (it's near our presidents home in Heliopolis and I knew they would notice me) and he said "etfadal ya basha" (I am starting to love this sentence)

I merged 2x30 secs exposured RAW images to give more light on the right hand side (the traffic was moving much slower compared to the left side) then took it to my good old Lightroom to treat the colors in an appealing way.

Hope you like it.

There's been much said about the sensitivity of the D800's sensor and the accuracy and spot on technique required from the user. I'm using this camera much as I did with my D80 but I am aware of the diffraction limit, decreased DoF that comes with FF, the recommendation of using mirror up before exposure, shooting wirelessly, using live view to focus etc etc. All this I have to get to grips with.

Headed off to Clevedon to test the camera on the pier.tonight. Not sure the image is as sharp as it could be, I'll have to work that one out.

Lubitel II, a Russian TLR camera. I have used this with black and white film and got some interesting results. This model was produced between 1949-1956. It takes 6cm x 6cm images on 120 film, has a variable speed shutter and a f/4.5, 75mm lens. Interestingly, the viewfinder lens above the main lens is rated at f/2.8 which lets in more light to the viewing prism at the top and gives a higher sensitivity to focusing.

My Style The Darkness

For this series,I was lucky enough to have a lot of subjects to practice on, since I was really testing out some focus settings. I have upped my focus sensitivity on this camera, and I think my keeper rate for moving subjects has gone up.

Life can be like high ISO. ISO is your camera's sensitivity to light as it pertains to the sensor in your camera. When your life is darker, you may have to raise your light sensitivity to cope with that darkness. What does raising your ISO in life look like? Well for me it's: meditation, prayer, fixing bad brain vibes, music, gratitude, being with those I love and getting out in nature.

I have learned to embrace the high ISO days in wildlife photography even though the images that it produces can be less than ideal. Those high ISO (dark) days may not produce the best art but it is still ART!

The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.

About this image:

Imaged in three key wavelengths of the electromagnetic spectrum of light (Hydrogen-Alpha, Sulfur-II and Oxygen-III), over a few nights (due to poor Astronomical seeing conditions, as a result of a very strong jet stream).

About Emission nebulae:

Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm. The blue light is from doubly ionized Oxygen ions (O2+) emitting at a wavelength of 500.7nm.

Force emanating from somebody or something: a force that is said to surround all people and objects, discernible, often as a bright glow, only to people of unusual psychic sensitivity.

Experimenting again! This time with strobes, overlays, colors, and digital painting. Any constructive criticism and a critique would be nice! I'm really proud of this one. The composition is much better than other dead center portraits I've taken in the past. I stayed up all night editing this with this song on repeat for hours. I was inspired by what happens in the video @ 2:45. While creating this, I was imagining myself lying on the bottom of the ocean under the northern lights.

I shot the original photo using a single light setup filtered through a red vase. The background was painted red as well. Half of the aura is a reflection from a plane window, the other half is digital painting. The final file ended up being 29 layers of curves, levels, hue/saturation, overlays, dodging, burning, and selective coloring.
