I'm going to start with hand-made photo paper, i.e. photographic emulsion spread more or less evenly on some nice fibre paper. Recently I prepared a couple of papers, and they - as one may expected - curled, curved and waived heavily. This may cause problems when enlarging or contact-printing. My idea is to wash and hot-dry them before exposing. Yet I am not sure if hot-drying doesn't fog the emulsion. Any experience?
