I don't think this is iridescence but rather it is the
characteristics of the wood grain which is a 3D structrure [. . . .]
Whatever the physics behind it -- and your description certainly makes
sense -- it's a /huge/ part of the problem here. Indeed, some of the
pieces use exactly the kind of maple you used as an example.
I just finished shooting some example pictures. The scene is
identical. The first shot is with only the left light on; the second,
both lights; and the third, only the right. Both lights are at a 45o
angle, both to the side and above. I've made no attempts at
correction; these are Camera Raw's defaults with the white balance
taken from a grey card.
I've come to realize that I'm screwed....
I've ordered a SoLux light that should be here late this coming week.
I've resigned myself to the fact that I'm just gonna have to hunker
down and hand-adjust each image to get the best compromise I can live
with.
(Unless, of course, somebody comes up with a miracle fix....)
