First the setup...
Two novatron 500 ws monolights using shoot thru white photoflex umbrellas. We're trying to do product photography and the subject is a medium sized jar of jam. The tips of the umbrellas are no more than a meter away from the jar. The jar is on a white paper background. I know this isn't the optimal setup for product photography so please hold your critiques - working with limited equipment and this isn't the problem.
The camera is a Nikon D5000 set to manual mode 1/125 F5.6 18-55 nikon lens at ~55mm. White balance daylight, ISO 200 - 3200 (explained further below). I tried shutter speeds between 1/25 - 1/200 to see if there was a sync problem but there didn't seem to be. The flashes are being triggered by the on camera flash set at minimum power. The studio flashes are both set at slave. The studio flashes are definitely firing every time.
The flashes are set to high range and full power.
The photos are coming out unbelievably dark. I can't imagine why. Even at 3200 ISO and F5.6 they are not total whiteout. They are maybe 1 stop overexposed max. Does this camera have some kind of setting that overrides manual mode and does some crazy nonsense? I shoot with these same studio flashes with a Nikon D70 and at full power with just one light i could totally overexpose a human model at F9 - F11. This was years ago. Do flashes go bad?
To thicken the plot I got a simple point and shoot camera (Nikon S220) and triggered the flashes with slave again using the on camera flash and I got total white out. Checking the exif data I see that the point and shoot used 400 iso, F3.1 and 1/30 sec. As a control the same scene from the point and shoot at F3.1 ISO 800 and 1/30 looked quite underexposed so ambient light is not playing a roll here.
What in the world is going on? Factoring in the point and shoot would make me tend to blame the D5000 but I can't understand how.
