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]

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]

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]

This is the sixth in a series of posts on color reproduction. The series starts here. In my last post, I suggested a “perfect world” approach to generating compromise matrices. This approach depended on the ability to generate targets with patches of arbitrary spectral reflectances. This is currently not practical. Bummer. Forget about it, right?… [Read More]
