sorry kato but this shit fizzle is telling you is fucked. since i am a know it all according to the fizmaster , well here goes.

you surely dont need 3 lights, just one positioned properly will work for 95% of all your shots.

white backgrounds suck.
at the very least use photographic background paper that will not bounce the light back but instead absorb it.
if you cant get graduated (which you can on the bay for 30 bucks) then get grey as it helps keep the reflection down.
a white background is gonna throw the white ballance off on the camera settings which will in turn give a bad pic.
about the only thing fiz said that was worth listening too was the dont use a flash unless you had no other choice.
fizzle you are a little puffer.

for the most part your advice sucks, there i said it!!!
