Thanks for the dial calculator. I downloaded it and am going to make one.
I have been using something similar but it is a bit more cumbersome. I made
a long slide-rule with all of the f-stops and speeds projected beyond my
handheld light meter. The only information my slide rule has that the dial
doesn't have is that I have included f-stops and shutter speeds halfway
between each of the standard settings. For example: the extra f-stop
between f/22 and f/32 would be f/27.25. I have done this all the way up to
f/4096 and 16,384 seconds (or 4.5 hours). Most people don't need to go that
high but you never know.
