Great guide. I just got my first DSLR (canon eos 400d) a few days ago and am trying to figure out how the balance all 3 myself right now. I think I got my macro settings down goodish. 100 ISO, F10 f-stop, 1/60 shutter speed, and using my florecent light WB. I found this produces the least amount of wash out for me and my current kit lens.
This is really an in-depth hobby/field.
