This is one of
the most important pieces of kit in the darkroom. As already
mentioned temperature is one of the main controlling factors in the
processing of your films and prints. It is important that you have
good quality thermometers that are graduated to at least half a
degree but a quarter of a degree is better and one that has a thicker
line at the vital 20 degrees C. It is a good idea to have a
thermometer for each of the chemicals you use in the processing of
your films and prints as it will stop cross contamination.Also there
will be no hold ups if you break one. It is recommended that you keep
to one type, preferably alcohol as it is safer than mercury. If a
mercury thermometer breaks it will contaminate the chemicals it comes
into contact with and fog any prints that are being processed at the
time.Sunday 11 December 2011
