Just purchased a Nikon SB600 Speedlight today with a plastic diffuser. However, from a video I am watching it looks like I am going to eventually need a cable to move the flash away from the camera. Also, possibly another tripod to hold the flash to one particular side. The cable they sell is about $70 or so which is outrageous. In any event, I look forward to playing with the speedlight. I learned already that the two most popular speedlight settings are TTL and BL. With both TTL and BL activated and the camera placed in matrix mode, the speedlight illuminates most of what is in the frame very evenly. Using just TTL on the speedlight and switching to spot metering on the camera allows you to hone in on lighting only a particular area of the subject.
