Um… I would ID this iridescence as the infamous Photoshop morph. It’s strongly expressing traits for Vibrance and Saturation, and probably het for Contrast. And I’m saying this as someone who does a lot of photo editing, and loves good art photography.
I would be ashamed to post a photo with the saturation, vibrance, or contrast bumped up in a forum dedicated to animal breeding, where people are looking to see an honest representation of a breeder’s livestock.
When you’re gobsmacked by an eye-popping photo, look at the colors of every object in the photo. Is the skin on the person’s hand suspiciously hot pink or magenta, or otherwise unnatural? Is the grass greener than a truckload of fertilizer could make it? Are the areas of the person’s hand where the veins are close to the surface intensely blue or green?
If the answer to any of those questions is YES then you are probably looking at colors that have been altered in a photo editor. Are the shadows in the photo very dark black? and the whites in the photo all snowy white? The contrast in the photo has probably been increased.
If it looks too good to be true and is for sale, ask to see a photo of the animal beside one or more common objects that you’re very familiar with. A can of soda with familiar shades of blue and red. A bag of Reeses peanut butter cups with the familiar orange. A brown paper bag, or a steel-gray silverware. The colors of the known items should be exactly what you expect.
If you’re a seller who wants people to trust your image, photograph your animal with a photography “gray card” - a strip of card paper printed with a square of black, white, and a particular shade of neutral gray.
There are many good reasons for playing with Photoshop settings when you’re making photos that are not intended to be regarded as an accurate representation of the subject. If you’re presenting such images in a context where people expect an honest portrayal of the subject, the only good reason for tweaking those dials is when the photo did not capture the real-life appearance of the animal. Then you adjust it just enough so it looks exactly like what your eyes see. I can’t think of an honest reason to go beyond that.
A forum category for posting reptile art photography would be a very appropriate place to put these photos. Or a category for humor and trolling.
