  1. Regarding noise, ISO, and chip sensitivity. A digital camera sensor has a sensitivity of only one ISO. In my Canon it is ISO 100. If I set my camera at an ISO of 200 then the camera exposure meter chooses a F number/shutter speed combo that underexposes the ISO 100 chip by one stop. The camera knows this. The camera internally boosts the underexposed information coming from the ISO 100 chip by one stop. This makes the final boosted signal correct to ISO 200. The Camera then saves the ISO corrected information to a RAW or a JPG. However in boosting an underexposed signal
  2. mid $$ editorial royalty free And you only talk about sky replacement like it is something new? You bunch of wimps. How about replace everything? 3 shots taken in British Columbia combined to make one, done in Photoshop 3, many years ago. John Mitchell probably recognizes the location of the totem pole.
  3. My experience in picture selection meetings for book covers is that art people can visualize a vertical crop from a horizontal image when the group is looking for a vertical final image. However word people have difficulty visualizing and tend to default to a vertical original shot, even if the vertical crop from a different horizontal is a better image. Both types, word editors and art designers are in picture selection meetings. However the word people tend to be more senior and have more clout. As the photo editor I always presented a selection of images, some vertical some hori
  4. Nuclear Power plant about 15 KL from my home. Shot shows a relationship between wildlife and nuclear power. $$$ Editorial royalty-free. Usage: Single company - multiple educational editorial use only
  5. Here is the argument for thinking about post processing before you make an exposure. I knew when I shot, that I wanted to make the image dark and foreboding but the tombstone to be emitting a spooky light. I could have underexposed the shot, and then lightened the tombstone when I processed the image. However digging into the shadows of that very underexposed image would result in a lot of noise in the lightened tombstone area. So I exposed the overall shot for the tombstone. Then I darkened the overall shot in Post while holding back the tombstone area only
  6. The first time I went into that site was 1964 on assignment for a postcard company. I was paid up front, so gained no stock images, but that was OK by me. On that 1964 trip I carried in a 4X5 speed graphic, heavy tripod and a case containing film in holders. The trail was long, wet, hot, overgrown, and mosquito infested. The experience was more bushwhacking with the weight of the earth on your back, than hiking. The site was known to First Nation people and a few locals so was absolutely pristine when I arrived in 1964. There was a house sized sacred rock covered in petroglyphs in
  7. Autumn in Toronto. I think entering the forest is like entering a cathedral. Light streaming down through translucent leaves like light through stained glass. Multiple shots with a super wide angle lens combined in photoshop. All alone for the morning on a little used side trail. Covid-19 stay away from my door. More light coming through translucent flower.
  8. The Nikonscan 4000 and 2000 do a second scan when IR is turned on. The first scan is for the transparency normally backlit. The second scan is angled light only glancing across the surface of the film that highlights any dirt or scratches sitting on the surface. The scanner software takes this second scan and uses it to apply a clone effect to the first final scan, to areas of dust that were highlighted in the second scan. This cloning results in a softening of the overall first scan. If the film is particularly dirty there is lots of cloning and the softening is even greater.
  9. Same image rotated and flipped to gain second image. If you are shooting straight down there is no "up", therefore both versions of the same shot are valid. Last of the fall flowers in Toronto. Full frame Canon 5Ds hand held 100mm 2.8 Macro 1/200 F11 ISO 400. This is a small flower, so F11 for focus depth on central bloom, but F11 made rest of image too in focus. Therefore blurred and darkened rest of image in software to place more emphasis on sharp, properly exposed, central bloom.
  10. Everyone is a photographer these days, like this industrial climber photographing the underside of a railway bridge for inspection purposes. 400 mm from a pedestrian bridge that parallels the railway bridge. The sumacs have turned autumn colour in Toronto. This shot was taken with backlighting, which has a stained glass effect on translucent leaves.
  11. Polar bears are thriving in the arctic today. The conventional wisdom was that they would not be able to survive because they needed lots of sea ice to hunt. In Canada bears used to wait until the shore ice froze over, and therefore loss of sea ice due to global warming would mean that they would wait forever and starve to death. Environmentalists continue to mislead the general public by publicizing images of the occasional bear sick by other means, and attacking scientists that assert polar bear are not endangered by the loss of sea ice due to global warming. The scie
  12. Good $$$ at direct 50% RF sale. Had a second image of same general area on same day for same price RF only sold for $ for presentation, but this fish sandwich image gives me more personal pleasure than the $$$ image. For the reason see the people in the non selling image below This image did not sell, but here is the reason for the personal happiness with $ image above. My sister-in-law on the left and my wife on the right. Happy times.
  13. Image created in photoshop using a scripted random pattern fill of 5 or so individual flower images defined as patterns. This wee fairy person showed himself to me while I was daydreaming amongst a field of sunflowers.
  14. Using LAB is a new one for me. I have always used all RGB swap with less control. Thanks DDoug I am going to try it. If you want to make big colour changes without affecting the neutral and other colours, swap channels in RGB only. This green maple leaf original was turned to red, by swapping the Red and Green channels. In such a swap any neutral colours or other colours will remain neutral or the same because there is very little difference between channels in neutral colours. Notice the blue colour at bottom left has not changed very much from the top original, only t
  15. The in camera histogram is read from the extra small JPG file made for the RAW file header. This header JPG is made from the camera's JPG settings acting on the RAW info, but does not capture all of the info in the RAW file. I only shoot RAW, and so I have the camera's JPG settings set as bland as possible. Everything in the camera JPG settings turned down, shoot in Adobe RGB. This bland setting produces a camera display JPG, and the camera histogram from it, close to the unprocessed raw. So now the in camera histogram, although read from the bland camera JPG settings, is very clos
  16. Jim Pickerell has been dispensing stock photo advice since the early 1980's at least. He considers himeslf a journalist. He has got under everyone's skin, both agency owners and photographers, at one time or another. He has been right more times than wrong. Many photographers have made more money because of his advice. Myself included. I think some of you are shooting the messenger.
  17. Yellow is a combination of the red and green channel with red higher than green. Images with yellow should be underexposed to hold detail in the red channel. Take a test shot at normal exposure. Consult the camera 3 colour histogram and note the red channel climbing up the right hand side, indicating that the red channel is overexposed and has lost detail and shifted the yellow colour towards green. Cut back exposure until the red channel meets the end of the histogram but does not climb up the side. So now, on the final exposure, you probably have red 254 Green 235 and blue 20 in
  18. Here is writer Harlan Ellison's "Pay the Writer" classic rant on freebee requests. https://www.youtube.com/watch?v=mj5IV23g-fE
  19. Illustration of the multiverse as predicted by quantum mechanics, using the scripted random fill option and a few other things, in photoshop. With covid-19 I have had the time to do some experimenting. Circumpolar Arctic horizontal view Australasian vertical view.
  20. Created in photoshop from a single image. The technique, using random fills, is explained here: https://fstoppers.com/photoshop/hidden-photoshop-script-allows-you-create-random-fills-507365
  21. I was unaware of the album cover when I did my shot. It was The Prisoner closing that inspired me. The shot of Patrick McGoohan being chased across tidal flats by a giant balloon. Made my man naked because there is no hiding anything from surveillance We all stand on each others shoulders. A few years after I made my image there was a Canadian movie made by an Inuit filmmaker called "Atanarjuat: The Fast Runner" that had a naked man, showing all of his naughty bits, running across a vast ice field. In a fit of patriotic fervor the CBC ran the film afte
  22. People objecting to being photographed in public is because of surveillance fatigue. Here is an image of mine circa 1995.
  23. All alone in the forest on a side trail known by very few. Part of Toronto's urban wilderness.
  24. Wilderness call. Composite illustration made from 4 photographs taken over the last 35 years, combined in photoshop. Style inspired by this top of the page 100 year old illustration with the scenic background here. Story of the artists is inspirational as well https://www.brainpickings.org/2020/07/30/harriet-helena-scott-butterflies-australia/
  25. Photographers having to refund proceeds of a sale paid four years old is just another nail in the coffin of Stock Photography. What happens if a photographer closes the account after a large refund of an old sale? Does the stock agency seize the images and continue to sell them until the debt is paid off? It would take an eternity at today's prices. Photographic sharecropping. The internet cries out for regulation. Facebook and others are now being asked to explain themselves by the US congress, so maybe it will happen. In the meantime if you are selling you
