Call it a useless tool all you want–the fact still is though that the Gary Fong Lightsphere is still an incredibly popular item with photographers. I’d still use one if my work required it! Giving what is essentially a bare bulb/ambient front lighting effect, it’s incredibly versatile. However, what most people don’t get is that you’re not always supposed to just point the thing forward towards your subject with the diffusion cap on. Instead, you’re supposed to position it different ways in different situations.
To help you out, Gary did a video a couple of years back on how to use it. That video is after the jump.
