Default Sunpak flat panel flash--anyone tried them?


Good little history lesson, Grant.

I've been photog, mostly paid one, for about 35 years, mostly knew the
score on that stuff (but hadn't thought of it in a while).

Only meant that actual ASA/ISO speed numbers did stay the same; I would
have thought that once an international standard was instituted, what
with metrical units and all, was a little surprised that ISO numbers
didn't go to more precise numbers. But Tri-X was ASA 400/ISO 400, Plus-X
125 for both, etc.

Of course, some pro films *do* have additional exposure compensation
factor, as tested for that particular emulsion run, so the "speed" is
just really a "purt good" ballpark figure.
