I shot four rolls of print film, one colour (400 iso) and three b&w (400 iso) using the same metering pattern and flash set up, with these results: I had the photos developed by a high street retailer and cd's made. what the f*** has happened? ....Sorry but I am new here and can't work out how to show my photos so you can tell me. What has happened is that I have correct exposures for the colour print film, which were developed in store and terribly overblown overexposures for the black and white print film. Aren't machines able to deal with these problems? Or is it something I have done. I know it will be hard with no photos to show you but I would appreciate some ideas.
