To be clear, these images are made with a digital camera and printed on metal/aluminum. These are not actual tintypes made with a wet plate camera. With that said, I have attempted to digitally replicate the way collodion responds to light by comparing a real tintype image of a GretagMacbeth ColorChecker target and a digital image of the same target captured with my digital camera. I created my collodion "recipe" by adjusting the color sensitivity and tonal curve of the digital image until each color patch of the color chart resembled that of the real tintype. While nothing can compare to a real wetplate image, the digital results are stunning when printed on metal/aluminum.
