If you're compressing an intensity curve on a spectrum to three samples (RGB), you're always going to lose information, regardless of what your original sensor was capable of.
Basically someone is throwing balls with floating point numbers at you and you have to sort them into three buckets and a trash bin, then you only report the number of balls in each bucket.
For all I know that photographic technique doesn't even capture any part of the spectrum that falls within the RGB area.
I don't know much about these photographic techniques and their terminology, so I had trouble looking information up, but it appears that the technique captures blue and ultraviolet.
- amluto 6y agoI have no doubt that wet plate photography does not closely resemble any part of our eye’s response, and Bayer filter designers put a decent amount of effort into getting (a nondegerate linear combination of) our cones’ response. And the potential or UV and IR sensitivity is a good point. It could nonetheless be interesting to try to learn a 3-vector (r, g, b) such that the actual linear-light output from some real camera dotted with the vector is insensitive to tattoos.
