I am 95% a bird photographer and I have no experience in studio work, I haven't even used a flash (almost). Now I am about to photograph illustrations in a book. I think my 150/2.8 lense will work (it is the shortest I have), but I really don't know anything about how to light up the book pages. Do you have any recommendations?
The trick is to avoid reflections, light the image evenly, and of course capture at the highest quality with bracketing the exposure. I have copied photos using north light from a window and a large white reflector on the side of the original opposite the light source.
The hardest part is getting the paper to lay flat and get the camera perfectly perpendicular to the paper, otherwise you will get distortion. A scanner solves both of these issues. Not to mention lighting without shadows, etc... Oh, and a D800 owner will want to argue this, but scanners have much higher resolution (esp as the paper gets larger)
If you are interested in learning how to photograph stuff like that. I can highly recommend
"Light Science and Magic: An Introduction to Photographic Lighting" by Fil Hunter, Steven Biver and Paul Fuqua
It is a textbook on how to light things while eliminating glare and other unwanted reflections.
Good luck with this.
