Quick Reference Photographic Trouble Shooting. SLR.
There are six main ways you'll get fuzzy images:
- Your shutter remains open longer than you can hold
your camera still.
- Similarly, your subject can't keep still for the
length of time that your shutter is open.
- You have problems focusing the lens on the subject.
- The aperture of the lens is wide open (a small number
on the f-stop)
- If you use a very fast film then any enlargements you
make from negative can appear unsharp due to the course grain of the
faster films. Speed is determined by the ASA/ISO value attributed to
the film. A value of 50 is a very slow but very high quality emulsion.
You'll need a longer shutter speed to accommodate such a slow film so
it may be very difficult to use. A much faster film for example a 400
will give you shorter shutter speeds but will be far grainier in
- A film that is badly processed, for example developed
at too high a temperature, will give poor quality photos. The
individual silver crystals in the emulsion clump together and give
horrible grain and an unsharp poor quality photograph.
