Currently I own a Canon 60D, some lenses, a Metz Mecablitz 58 AF-2 flash and two Yongnuo YN-622C flash triggers to fire the flash off camera. One sits on top of the camera, and the other one goes on the flash.
What I am finding though is that with my single flash I cannot blow out the background to white because the flash is not powerful enough. Therefore, I have concluded that I need at least one, probably two, more flashes (both of these new flashes would face the wall to blow it out).
With these two new flashes, though, I will also need (1) light stands (2) umbrellas or softboxes (probably softboxes as there would be less light spilled); but most importantly I will need 3) some new triggers to control my two new flashes.
My current Yongnuo YN-622C flash triggers cannot change the flash mode and power from the camera (either via the camera menu or the trigger on top of camera, which would save me from having to go over to the flash, fiddling with it and getting back into position to take my photo. With more than one flash, I would really like to have this ability.
Question - What triggers are available that allow you to change the mode and power of multiple flashes from where you stand?
