Use alkaline or silver oxide. Any small error in exposure caused by the
difference in voltage is compensated for by the exposure latitude of the
film. I had my OM-1 modified with the Schottky diode setup, works
That depends o nthe film. It would be find for negative film (B&W or
colour), but I think it would be too far out for colour slides. You could
probbly compensate by mis-settign the film speed control though.
perfectly. I believe it would probably work just as
well without the
diode.
And as far as the diode goes, I have heard one person claim that it is
entirely pointless because the voltage drop over the diode varies so
much with the ambient temperature that the compensating effect is
essentially nullified.
I will have to measure it, but I didn't think the voltage drop varied
that much over the normal temperature range.
