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]

This is the fifth in a series of posts on color reproduction. The series starts here. This is a nerdy and mathematical, though equation-free, take on how to create compromise matrices. If you don’t know what a compromise matrix is, start with the link in the paragraph above. If you just want a semi-technical view… [Read More]

This is the fourth in a series of posts on color reproduction. The series starts here. This is going to get pretty technical, so I’d like to first give the “See Spot run” version in this post, and get into the details in the next one. If you’re not into the techie stuff, you can… [Read More]
