Umut,

You would probably appreciate the build quality of the SEI Photometer. The only issue in this discussion is that it has a sensor (the eye) that does not correlate 100% to film. I wonder what sunglasses I would have to wear to approximate the response of Tri-X.

Probably something pale Magenta to pull down the Green. Next time you see me in the field, I'll be wearing rose-colored glasses.
