question regarding polaroid t55 film-- over the weekend, an imprompt shooting si tuation left me to put exposed t55 film in water for several hours before i imm ersed the film in sodium carbonate. the result has been puzzeling. one batch of film cleared and looked normal as i have done this once before. the second b atch of film did not clear. a blackened image remained and the emulsion was very soft and became unattached to the gelatine film base. the dating on the film wa s 3/98-- a few months over the recommended time. is this the problem? thank yo u for your answers.
