Hi, I'm learning how to photograph my paintings and looking for some pointers. I was planning to get a couple of umbrellas with light stands. Then I saw this page http://www.photoflexlightingschool....ng/Product___Still_Life/2D_Artwork/index.html They use a couple of lightboxes facing each other and they're promoting their own product which is too expensive for me. Is there another alternative to this? I'm sure there are many ways to do this that's cheap and effective. I could just use plain old dome lights with tissue covering them and position them accordingly. What kind of light bulb is best for paintings?
