Reproducible photographic processing using two bath development

摘要

Processing colour photographs by the two-bath development-enhancement process uses the steps of: (a) exposure; (b) development with colour developer; (c) enhancement with hydrogen peroxide (H2O2) or a H2O2 precursor; (d) fixing; (e) washing or stabilisation; and (f) drying. The novel features are that:(1) the material is washed for 1-60 seconds at 10-40 deg C and a regeneration ratio of 10-1000 ml/m<2> processed material between (b) development and (c) enhancement; and (2) the displacement rate on transfer from one bath to the next is /} 40 ml/m<2>.
