Hello everyone, Hope your photo-making is going as good as mine (okay, maybe not *that* good!) Have a friend who has a very nice setup of: Nikon D100 Metz CL45 SCA 3000C hot shoe The problem is we can't get the Metz to work in TTL mode. If I manually set the Metz to an aperture, and then set the camera to the same aperture, the flash goes off and the picture is taken fine. But as soon as the Metz is switched to TTL it refuses to fire when the shutter is pressed. So I went into the Nikon menu and checked that the flash mode was set to TTL... and it was. Could you please tell me what I should do to try and get the camera to automatically create the exposure using TTL metering and the Metz? Here are some answers that might also help me: What mode should the camera be set to? P, A, S, or M? What settings must I ensure are set in the camera? What other approaches should I use to get this Metz flash to shoot TTL? Ideally my friend would like to have the camera set to automatically fill-in with direct flash at the same exposure or a stop under. (Is this possible?) Thanks to all your help! Andrew
