After receiving this question I thought why not just trying it out within a hands-on video. I didn’t had tested this beforehand, so let’s see:
First things first: I had to shoot today’s video with my old digital video camera, thus there is no HD video today.
Second: it’s not for you if you already earned your salt using flash.
Anyway, if you just starting out or are used to avoid using any kind of flash out of frustration, this might be interesting for you.
