"Weird meter results"


Huntington, WV, US
          

Is there any reason why a brand-new light meter would give good results under ambient daylight, but recommend readings that yield flash exposures that are two and two-thirds stops overexposed? It's a Sekonic L-478DR, and I'm using it with SB-800s, a D700 and Pocket Wizard TT5s. And yes, I have purchased Sekonic's ridiculously expensive exposure calibration target and did an exposure profile on the D700.

Is there such a thing as getting a light meter "lemon?"

John,

I'm not by my equipment, but here's my guess. You need to set bank C2 for that. It must be set so that it triggers only. If not and your camera is set to the wrong f-stop, the camera will meter and steal the show from the Sekonic.

2 and 2/3 stop overexposure? Sounds like the incident dome is pointing at the subject rather than the camera.

Scott,

Thanks for pointing me in the right direction. I had made the mistake of following Joe Brady's and Mike Wallace's online tutorials, which ridiculously oversimplified the instructions for adjusting the transmitting TT5's settings.

Armed with your suggestion that perhaps the camera was stealing the show from the meter, I started searching online, and eventually found a step-by-step tutorial that walked me through the entire process.

For the record, I can't believe the Brady and Wallace videos didn't mention using the Advanced menus to make the adjustments. And Sekonic's instructions were awfully darned confusing. Grrr....

At any rate, all is now well. After I reprogrammed the triggering TT5, I began getting exposures consistent with the meter's readings.

Again, thanks for pointing me the right way.

John

John,

I'm glad it got you pointed in the right direction. I haven't circled back lately, but the meter is supposed to meter each group individually and cumulatively. That way you can tweak your ratios. Last I checked, it only takes a cumulative reading. That's not impossible to work with, if you think in terms of power levels and not f-stops.
