Been experimenting the last couple of days with off-camera flash. Not entirely to my satisfaction, but learning every second more and more about (studio) flashing.
At the moment I have a Nikon SB-600 which is nice, but two (or more) would be a lot nicer (Photography Acquisition Syndrome, anyone???). Also some stands, claps etc. would be nice. Getting a flash off the floor (or cases) and into the air requires a lot of ingenuity.
This way, the gear-wish-list keeps growing and growing. Oh man, that Nikon 200-400mm f/4 lens is not getting closer this way....
