This is a self portrait i recently did on a location i scouted out. I invested in the 580EXll strobes because I liked the portability idea of them and this is one example. This location was "off limits" and i really was taking a chance being here at all, so it was good to have a very light set up that I could walk in with and run out with too.
The strobes were set in Manual mode (everything was actually). the main was set on a adorama lite stand (very light and portable) against the window wall and to the right high up about 7ft. The other strobe was on camera (only brought one light stand) and rotated to bounce of the wall behind me, just to add some fill to the room as I exposed for the window light.
The infrared signals from the strobes were able to easily communicate with eachother and even better, the Canon 5D mkll gave me the abilty to adjust the output of each right from the camera.
It is not technically perfect, but i don't think I would have got the shot if I had to lug larger equipment to this place.
I have just learned also that pocket wizard makes a transceiver that is dedicated to the Canon DSLR and will transmit E-TTLll info to the other strobes. Now this is getting interesting.
