<b> A flat diffuser is very useful for calculating lighting ratios but

it still will not meter subjects that emit light. </b>

Actually, that is a rough approximation of what we do for a

standard beam from a black emitting standard. [in A of course;

;<)] Here, we are not taling about an emitting source; we are

talking about a transmitting source. It is different.

Jay; depends on what you want.

I think we had this discussion before. From the Leicas, I have

used a IIIf and an M3 at temperatures as low as -56F. They

worked fine [although if I were doing this on a regular basis, I

would have them winterized; particularly the lenses]. The

problems are more peripheral. John has mentioned one. Static

discharge. I am not sure that I would like his grounding option

during a lightening storm or during cloud formation on a peak.

One time at 14,000 ft with my hair standing up on end was

enough for me. ;o)). Move the film slow. Another is to remember

not to exhale on the finder; it not only fogs but it ices. If you have

batteries you will need to keep them warm. Little things like this

you learn.

In answer to another question, everything I do is art. ;o]
