F100 flash exposure errors

greenspun.com : LUSENET : Camera Equipment : One Thread

I'm an experianced photographer.

All other modes work fine, including complex automatic fill-flash. When I make a photo entirley lit by flash I need to dial in +1 stop of compensation every time. Whether I use one flash on the camera at 20 feet or three flashes synced to gether in a complex macro set up, the camera with Velvia needs +1 stop compensation or underexposesa stop if I don't.

I can shoot in manual mode at 1/250 or just leave it in program in dim light, same thing if the flash needs to be the sole source of light. Same results with one SB23 or two SB28, same result with SB28 set to standard TTL or matrix TTL. Same results with AF or AF-D or manual focus lenses. All consistantly one stop under. Again, it works great for fill or without flash.

Anybody else seen the same thing? I don't want to let Nikon's people screw with the camera if they all do this. I can handle dialing in +1 every time I shoot flash only. Thanks!

Have you tried to set the flash to standard TTL mode instead of TTL multi-sensor balanced fill flash mode? The former is designed for use when flash is the main source of illumination, the later for fill flash. I don't have either the SB-28 or SB-23. On SB-26, the flash can be switched between the two TTL modes by pressing the M button.

Chuck: Yes, I have tried both of those modes with the same result many times. It's consistanly under one stop, which +1 stop of comp fixes; I just don't like having to remember to set it as I go from fill to full flash! KR
