On another forum there was a reference made to "The Strobist School". I gather that this is an photographic esthetic involving off-camera flash.

I didn't want to seem ignorant in THAT thread and I didn't want to seem challenging the other photographer. So I ask here...Hasent off-camera flash been a staple of advasnced studio technique for just forever...or is this technique like "Painting with light" that was the fad a hile back?

Any input on this?
