Just link. It just shows how hard it is to get the right shot. Not many people have access to the remote flash guns (slaves).
Im thinking of getting a wiless flash for my 350D, for doing my tank shots. Its expensive though at around Â£400 for the control unit and a wiless flash.
I have a Nikon SB600 which I use off camera with a sync cord. I plan on getting an SB800 and using it as the master, using both flashes off camera wirelessly. If only I didn`t want that damned 70-200mm f2.8 VR.
I have used a light box on my 60cm, which should give good results with a bit of experimentation.
