I'm slowly getting a handle on using the sb-600 flash.The folks on this website have been quite helpfull and i appreciate it. I just have a couple of questions to help clarify a few things. When indoors, with the camera on manual i have been metering for the room on center weighted, and setting shutter speed to underexpose for 1 stop.Is this done with the flash on or off ? Does the camera care? In the limited cases i've tried it doesn't seem to matter. I haven't read anything about direction of the flash head. Indoors i've been trying a Demb with the head pointed up at 45 degrees. When using flash outdoors on a bright sunny day i have my D300 set to 1/320(FP) flash sync speed. At 1/320 shutter speed, ISO at 200 flash on TTL-BL do i adjust aperture to expose properly. Secondly what metering do i use outdoors? Things a slowly coming in focus. Thanks again for your help.
