![]() Reddish cast to film PROBABLE CAUSE -Low development temperature -Underexposure in camera -Developer exhausted -Developer too warm -Overly-vigorous agitation in conventional tank -Improperly washed 5247 films -Too little development -Too much development -Exhausted Blix -Blix temperature too low -Blix time too short REMEDY Reread and follow all instructions carefully on temperature control, solution, capacity, etc. Negatives look OK but loss of highlight and shadow detail. Negatives look OK but prints are a bit too flat. Black “dirt” specks on negatives which print as white spots. TROUBLESHOOTING PROBLEM Thin negatives Negatives appear more magenta than more normal with higher density near sprocket holes. For different times and temperatures consult the film instruction sheet. When exposing these films at ASA 800, increase development time by 40% and, when exposing at ASA 1600, increase development time by 80%. ![]() 3.5 min x 1.25 = 4.40 min) CHROMOGENIC B&W FILMS When exposing these films in the range of ASA 100-400, use the standard development times given in the time/temperature chart. When Exposure Change is: ISO Speed Increase Development Time: 2 stops under 4x normal 1.5x (i.e. In other words, pushing an ISO 100 film two stops to ISO 400 offers no benefit since an ISO 400 film is already available. When pushing is required, start with the highest speed film available. As a rule, pushing should be done only when necessary (i.e., when higher film speed is needed) because negative quality does suffer somewhat. PUSH PROCESSING All color negative films suitable for the C-41 process can be underexposed and processed for higher than normal film speeds by extending the development time (push processing). If you choose to operate under these conditions, our best advice would be to process a small piece of test film, and on the basis of these results, decide whether or not to commit valuable pictures to the chemistry. Otherwise, partially used working solutions left untouched for a week or more might have changed so significantly that you would suffer a dramatic decline in results. This procedure is somewhat risky unless you process some film every day or so to monitor chemistry performance. ![]()
