What's the best lighting for desserts?

[tirediron]

This is like asking "What is the best lighting for GMC trucks?"; it doesn't matter what kind of vehicle you're lighting, the theory is all the same. Likewise with food, lighting food is lighting food; there are differences for light food & dark food, reflective food & matte food, but in general it's all food. The only piece of important information you haven't been given is the 'lighting bible'. Buy a copy of that, and you will have all that you need.

Also, it doesn't hurt to remember that just because you don't understand an answer, or the 'how to' doesn't jump out at you, it doesn't mean the answer is wrong. I just had a quick look through some of those links, and there's a LOT of good information in them. I would strongly suggest you put cake photography on hold for a bit and spend a few weeks studying lighting and food photography in general. Once you know the difference between a scrim and a squid, and the meaning of "the angle of incidence equals the angle of reflection" and the inverse square law, you will have enough of a grounding in basic theory to understand some useful answers.
