Just a short while ago we had some discussion about reciprocity
correction charts for various films.
I would like to suggest that some of you may be interested in using
the BTZS ExpoDev software for exposure calculations in the field,
especially when dealing with complicated situations that involved
filter factor corrections, reciprocity corrections, and/or
corrections for bellows extension. I have been using the ExpoDev
software now for about 6 months, and during the last month or so have
made heavy use of it in work that often involved significant
reciprocity and filter factor corrections, and sometimes bellows
extension corrections. I am very pleased with the results, with
excellent exposures on nearly every shot. In fact, I very much doubt
that I could have done as well in making these complicated
calculations manually as did the program automatically upon entry of
just a few pieces of information.
For simple lighting situations the use of the program is probably
overkill for most of us, but for those really complicated scenes I
recommend it highly.
