What does film speed mean and how does it affect picture quality?
A. ISO (International Standards Organization) film speed numbers indicate how sensitive film is to light. The higher the number, the greater the sensitivity. Slow films have the richest color and best sharpness, while fast films are better for stopping action, shooting in dim light without flash, or extending the maximum range of your flash. Q. What film speed is best for typical family and travel snapshots? A. For mostly outdoor shooting, use ISO 100 or 200 film. For indoor shots requiring flash, ISO 400 is recommended to extend the flash range out further. Q. Does slide film produce higher quality photos than print film? Most pros whose photos are published in photo magazines shoot slide film. A. It depends on how the photo will be used. If you want the final result to be a print, then shoot print film. If you are shooting for publication, then slides are generally preferred. It is possible to make prints from slides, but the cost is higher and there is usually a loss of image qualit
