Hello there. I'm having some problems while developing my black and white film. I'm new at home developing and I developed 5 rolls so far. They all looked good fresh from the development tank but today I was scanning them and I notice theres a general lack of contrast and dark and sometimes light beams of light coming from the sprocket holes. I'm using a 2 roll Paterson tank. I use LC29 as a developer and also Ilford stop bath and fixer. My film is all HP5 at its 400 normal ISO. I develop for 6:30 min, stop bath for 30 seconds and fixer for 5 minutes with a 1 minute prewash before everything. Everything exactly as MassiveChart and Ilford suggests. I agitate 10 seconds at the start of every step and every minute after that. I agitate slowly rotating the tank over itslef and twisting it at the same time. As you will see on the images below theres a general lack of contrast and a lot of foggines... also parts of the images seem more develop than others, apart from the darkness following the sprocket holes.. I did some research and I found that it can be because of a lack of proper agitation (maybe my slow rotating movement is not enough to get fresh developer everywhere so parts gets underexposed) But I also read that the white beams over the sprocket holes can be caused by over agitation so the two solutions seem contradictory. I would highly appreciate any feedback you have to offer as I dont like the idea of keeping "badly developing" rolls of film until finding the solution. Thanks in advance to everyone!
