OK, I haven't been very active with film lately and the few undeveloped rolls sitting in the black plastic bag for 6 months can tell that. For an average bw film that is not really a big deal, but it seams the Shanghai GP3 does not really like to expose his latent images to the protective layer-paper. Resulting in a nice watermark over all negatives. Lesson to learn. Shot with the Agfa Isolette a while ago... yes, early this year.
