would like to know more detail of flash photography with R8 and ttl with Sf-20. Main concerns with fill-in flash, does it work with R8 program mode? Is it better to use flash with decreased power eg: 1/2,1/4 or 1/8 power,to me this just reduces power and the camera will compenste for availabe light? Also when using the flash what good does it do to place time shutter on 1/30th when on program mode when TTL will automatically put sync on 250/sec. For now I just use Camera on Manual mode with sync at 250/sec set my arpeture accordingly then turn on fash on manual and step back approximately 4-6 FT. or close arpeture 1-2 stops. Or can I keep it in program mode and adjust the EV-1, or -2 to achieve a good fill -in flash. Please don't tell me that the camera will take care of this on its own, I know better. When taking pictures in the daylight in program mode with flash on TTL the flash never fires due to enough daylight, not giving any fill flash. I know what to do with my Nikon F3 but I would like to get the straight dope on this for my R8 to use it to the fullest capability. The instructions regarding this aspect are vague in the R8 manual and SF-20 flash manuals , they just keep repeating how the adapters work for converting to TTL and Metz flashes. HELP ME.
