Dear All,

Does anyone have any experience of TTArtisan light meters,? I though that they had a good reputation, but see below...

I bought one (Series 2) because I wanted to test them because I haveb een getting some odd results with my IIIf M3 (my Weston Mk V has finally stopped working properly). I normally shoot "Sunny 16" and wanted to understand if the issue was me, developing (proffesional) or what.

I was comparing what I would expect to get from Sunny 16 with my digital Fuji and the LM. I tested in a variety of light levels and degrees of shade.

To my amazement the LM and the other exposures agreed on only one occasion, when I was pointing the LM and the Fuji at a white wall in full Mediterranean sunlight (seriously f22)! Otherwise they were miles apart.

Both FUji and LM were set to 400ASA. When I shot the scenes with the Fuji the images were, in general, fine.

Anyone any thoughts/explanations? Of course the Fuji has a zoned meter, but still...

Thanks in advance

My first thought is whether the Fuji and the Meter are "looking" with the same field of view? That could account for some differences and explain why they concur on the white wall test. Was the difference something consistent or varying?

I recently purchased a series II TTArtisans light meter and tested it in a variety of lighting situations against an accurate Gossen I've been using for years. There was a consistent 1 stop difference. I made sure the slight differences in the field of view wasn't the issue. After thinking about it I realized the answer was to simply use the included screwdriver to reset the aperture dial on the meter by 1 stop. That did it and I've been happy with it ever since. I suggest you retest your results with a 18% card/subject to accurately determine the difference, and if there is consistently a difference and you are confident of the Fuji results, that you can reset the aperture dial on your new meter, retest it, and you're all set. It shouldn't take more than 5 minutes or so to check everything out.

I use one on my M2, all the negatives come out looking fine. I have also noticed that when I compare the reading with one of my digital cameras there's sometimes 1 or 2 stops difference but then both the digital capture as well as the negative turn out fine. Never really understood why that was but also decided not to worry about it.
