>>1253556experiment with the light from the back, top.... but you are better off to start with the basic 45 degree and a little overhead. if you have a bounce or a white foamboard it can help to bounce some fill to the nonflash side.
basically that. better with your remote. maybe not bulb. set it 2 seconds, click, flash, closes. too long, try 1.5, too long, try 3 seconds... just experiment. great about dSLR, you can chimp and see the results.
