I bought The Art and Science of Digital Compositing at Powell's Technical Books in Portland a year before I started my capstone project. It and Computer Graphics: Principles and Practice 2nd Edition in C were my main references. There was much less open source code to look at back then, and it wasn't as easily searchable either. Working on graphics, I could usually (though not always) resolve an ambiguous directive by trying different approaches and looking at the output. Does the result look like colored snow? Does the whole image now have a magenta tint? I probably need to try a different interpretation (or just fix my bug).
