I haven't read the book, but I've read his STS articles, and I want to read his book.

From what I've read, though, I've never understood how he could assume that the way we see colors change at different water depths is the same way a fish sees the colors change vs. depth. They spend their entire life IN water, with certain wavelengths always filtered out... we do not... don't you think their interpretation might be a little different than ours?

Also, the pictures I've seen him publish, well, let's just say that film grain reacts to light changes differently than our eyes do, so that's not completely accurate either.

Never mind the fact that most of us are concerned about anadromous fish, and they spend 90% of their lives in the deep blue ocean, and when they come into the rivers, it's a major change for them, not only biologically, but also in what's in the background... no longer is it mostly a dark blue or green background, now it's got all sorts of colors and textures... this is a very complex subject.
