@Tim,
thanks a lot for your generous help. How nice to lend some of your great experience.
They are mainly for files and books, it seems that I will set lights/strobes very defused, in order to avoid shadows, and use perspective control lens, ....

@Bart,
Thanks, Bart, sure, I will read the book u kindly recommend.
