Upon placing plate in revealing the operator opens tap when equilibrium balance product, is warned by plate noise should remove plaque developer delve into custom handwriting paper reverse after brief washing bath, which can be re in the water bowl who exactly used to measure duration development. If time pose was correct, the plate out second developer can be considered complete, surface washing, quick drying As gelatin layer is thin fragile, appropriate to ensure a long shelf plate, cover with varnishes based benzine. must absolutely avoid using French polish, liquid having last property dissolve aniline dyes contained in the starch grains, which inevitably would bring irreparable loss Light house shows in a small brochure attached to each packet a series enough plates long manipulation, which do ent not be regarded as indispensable. First, fixing no purpose, since it can no longer remain after the reversal, silver bromide plate. It might be as well as by chance, second development was sufficiently advanced.
