re: Photographing your cakes, do you use a special light?

I am terrible at taking pictures. Even though my cakes are only for the family, I would still like to take some good pictures of them. Have been reading about using a light box and came across these two tutorials http://thebearfootbaker.com/2012/01/you-are-my-sunshine/
and http://digital-photography-school.com/how-to-make-a-inexpensive-light-tent.
