I just shot my first roll of APX100. I rated it at 100ASA and shot in a room with available light coming from the windows on an overcast day. I was wondering what development times others use in similar situations. This is also my first opportunity to use Rodinal. I was going to try the manufacturer's suggested time for Rodinal of 8 minutes as a starting point, but I figured I'd ask you chaps for advice before I fill the tank.
