A couple pictures taken during ambrotype profile creation process. Emulsion watering, shooting and the developing by Anatole Green.
We’ve took 3 negative pictures on glass plates — normal, under and over exposure. After that have scanned them on velvet background as positive and made mLUT (multi-LUT) profile using our non-linear mathematics. How it works in Dehancer you can see on example below.
Those hues are natural as it is, without desaturation or colorize post-processing. In reality, the underexposed ambrotype also looks like a bronze-green, and the overexposure is more yellow.
