This is the eleventh in a series of posts on color reproduction. The series starts here. Sorry about the terse title. There are going to be a bunch of similar posts, and I wanted to make this one easy to find later. ASP stands for Adobe Standard Profile. I think you can figure out the… [Read More]
A naïve approach to camera/developer color accuracy
This is the tenth in a series of posts on color reproduction. The series starts here. Now that I’ve tested your tolerance for theory, let’s jump right into practice, at the deep end. Let’s say I’ve got a Sony a7RII in my hand, and I’d like to know how accurate the colors are when the… [Read More]
Strategies for 3D LUT camera profile generation
This is the ninth in a series of posts on color reproduction. The series starts here. As we’ve seen, three-dimensional lookup tables are more flexible and powerful than compromise matrices. That lets us do things with 3D LUTs when calibrating cameras that can’t be done with compromise matrices. However, that freedom comes with a price;… [Read More]
Metameric failure
This is the eighth in a series of posts on color reproduction. The series starts here. I said in the last post that I’d get to 3D LUT based camera profiles in this one. I lied. Sorry, but the story of this series on color reproduction, which started out as an attempt to explain how… [Read More]
Computing 3D lookup tables for printing
This is the seventh in a series of posts on color reproduction. The series starts here. There’s a more flexible way of color correcting cameras than compromise matrices: the three-dimensional lookup table (3D LUT). With it, you can do essentially everything you can do with a compromise matrix, and many things you can’t. Its use… [Read More]
