I have a question about push processing E200 film. On the box of the film it says "push to 800". On my last roll of film I had developed, I asked the processing lab to push to 800. They said since I had set my ISO to 200 they couldn't do it. Am I missing something here? Or are they giving me bull****? I thought since it was 200 film I set the ISO to 200. Can somebody explain this to me or refer me to a better lab that do push processing. Any help would be appreciated. There is another comet in the sky right now and I want to do things right this time. Debbie
Hi Deb, I think they're giving you BS, unless there was something you were trying to photograph that needed to be exposed a certain way with ISO 200 film. For example, if you take a picture of your friend in the daylight with ISO 200 film and have the camera set for ISO 200, you'll get the correct exposure. If the film is then pushed to ISO 800, the film will be badly overexposed -- in effect, you used a setting that was correct for 200 film on 800 film. But for celestial objects, the camera setting doesn't matter. You're probably not going to overexpose the comet. On the other hand, you will get more grain, which is objectionable, with 800 film. So you have to weigh grain versus exposure. If you're going to push it to 800, why not start out with 400 film? Just some thoughts. Best wishes, Joe
Over the years I've developed hundreds of rolls of E6 film and while there are times I might have said pushing was not needed or not a good idea, it would not have made sense to say it couldn't be done since pushing is just a matter of leaving the film in the chemistry longer. So if they said they can not do it either they don't know how to push film or (maybe more likely) the clerk you were speaking to did not know what they were talking about. Patrick p.s. Developing E6 is not hard to do. A roll can be processed and dried in an hour or less and you have total control over pushing. The down side is cost. Part of the chemistry has a short shelf life (unlike some of my B&W chemistry that I've been known to keep around for years...) so you need to process a lot of film to make it cost effective. astrodeb@charter.net wrote:
