Gossen Luna-Pro F Meter Problem
I picked up one of these meters inexpensively on ebay recently. I've wanted a decent meter for manual off camera flash work for sometime, and I couldn't resist the price.
So it's in great shape. Incident/reflected light seems to agree with my Nikon D300 within a quarter of a stop or so -- consistently -- when used on a gray card. This is great.
However, using it in flash mode doesn't seem to work. I've been messing with it for about 3 days now and the best I can do is get the needle to come about 2 stops shy of incident light levels without flash. So it is sensing the flash (flash is enough to trigger a reading), but the reading is just off completely. It's off by about 5 stops or so, I think.
I've tried it every possible way I can think of. The only way I can get it to do anything interesting is if I point it directly into the flash. And that gives me a reading that isn't useful at all, but it does saturate the meter (yippee).
Anyways, I think the flash portion of this meter needs calibration. Anyone experienced this before?
I've read there are 4 calibration controls on the inside of this meter. If they are labeled obviously, I wouldn't mind trying to play with it. I suppose the 4 controls would be for flash and ambient high and low calibrations (2 modes, high and low for each = 4 calibration screws). Do I take a Sunday afternoon and give it a try?

I don't have the same model you do, but my Digital F reads the ambient light along with the flash. If you're in a dark studio it isn't an issue, but if the ambient light is significant it will affect the reading.
Hope this helps,

its quite possible the meter has a problem too, have you contacted the seller regarding this?

Why not send it to Bogen Imaging (Gossen) and have it calibrated.
I doubt it would cost very much. I am sure they have the equipment to do it right. Then you won't be second guessing the exposure.
Good Luck and Enjoy your Nikons!
