Since some month i´m starting to learn gum print. it is an alternative photographic process which was used from 1890-1930  and one of the most difficult to learn as you really have to figure out your personal way. i had my first good results after i found the right sizing which for me is PVA. After sizing with pva you have to coat the paper with a solution of gum bichromate with pigments  As it is hard to find formulas  on the web i want to share mine for 2 sheets A4: 0,10 gram pigment with 2ml gum arabic and 3 ml bichromate. i use a grownig lamp from a local headshop my exposure time is between 6:30 and 7 minutes. hopseyou like my first results if you have any questions just contact me
