How cameras and people see color

December 7, 2015 JimK 12 Comments

This is the second in a series of posts on color reproduction. The series starts here. Before I get into today’s topic, I need to trot out a bunch of caveats about what people I’m talking about, and what I mean by seeing color.

December 3, 2015 JimK 3 Comments

In Tuesday’s post, I made a pitch for more high-quality slowish lenses on full frame mirrorless cameras. I also posted most of my little soliloquy on dpr. Over there, a good time seemed to be had by all; more than a hundred responses in the first 20 hours. One of those respondents took me to… [Read More]
