Hi again Kostas. The answer is that there is a desensitizing action on film sensitivity by the developer BUT you can still fog your film in white light. Once the developer is neutralized or removed by the action of a stop or washing, exposure to white light will do no harm, so fixing can be safely carried out in lit conditions. Karl
