Well I wanted to experiment with pushing film. Unfortunately, I think I went way too overboard on my first try. I should have pushed by only a stop, maybe two. However, I went for three stops. So I had Fomapan 200 exposed at 1600.<\/p>\n\n\n\n

The second problem I had was there were no published times for pushing Fomapan 200 to 1600 ISO for Rodinal. The Massive Dev Chart (https:\/\/www.digitaltruth.com\/devchart.php) gives you all sorts of times for film\/developer combinations. So I looked up a different film stock (I cannot remember which one it was) and found a set of stand developments for the film’s rated ISO and for when it’s pushed 3 times. The normal stand development was 1:100 at 60 minutes and the +3 push was 1:100 at 90 minutes. I carried them over to the Fomapan, which I believe was a mistake.<\/p>\n\n\n\n

When I pulled the negatives out of the tank after fixing, they were VERY thin. I knew that these were going to be problematic. Now, I did get a lot of usable images out of the roll, but most are on the edge of being not useable. The shadows are badly crushed, and the grain is very prominent.<\/p>\n\n\n\n

The third problem was with the banding around the sprockets. When I saw this yet again, I was sure I had no light leaks and figured that an actual light leak wouldn’t look like that. I also figured that Foma wouldn’t have that many bad rolls, so there had to be a different cause.<\/p>\n\n\n\n

I came across a useful website pointing out common developing errors (
https:\/\/www.olympus-lifescience.com\/en\/microscope-resource\/primer\/photomicrography\/bwprocessingerrors\/<\/a> ), and it suggested that the cause of the banding was due to over-agitation. With that information, I’ve adopted an Ilford style of agitation, which is slower and less frequent. So far I have not had the same problem.<\/p>\n\n\n\n
