I also want to find a way to measure the curtain speeds, but I can't
figure out how to do (even I know how to make it, I wonder I will pick
up the soldering iron again). When I found the exposure deviation of
left and right side is higher than 0.3 stops I will adjust the curtain
by trial and error, in most case it works but it takes time and
patience.
