The PM2 has a different display than the other ones, such as PM2L. It has "Optical Density" and "Exposure Factor" instead of filtration and exposure time. How do I convert them?
I have a paper manual for the PM2L/PM2A, but not the PM2 I have.
If you haven't yet discovered this site check it out....this gentleman seems to have manuals for everything (and if you find the manual, he asks for a $3 donation...well worth it to keep making it possible for him to continue to preserve these manuals and make them available.)
