With photography solidly
entrenched in the digital world we sometimes forget that not everyone has
hopped on that bandwagon. There is a
solid group of photographers who continue to use film for a variety of reasons. Of course this includes many Leica users. While most camera manufacturers have left the
analog camera world, Leica is one of the few who is still making film cameras.
Unfortunately,
manufacturers and suppliers of photo chemicals have dwindled to only a few and
many of the chemicals we got used to are no longer available. That made me think of an incredibly versatile
developing system my father used years ago in his studio.
His objective was to
maintain as much control as possible during film development. He did not like to rely on only one developer
where he could only alter developing time or dilution.
His developer consisted of
five base solutions, each with its own characteristics, which could be combined
in various proportions to achieve a wide variety of negative
characteristics. The system allowed
utmost control during development for under or overexposed negatives, or it
could be used to raise or lower contrast in normally exposed negatives. It could also be used as a variably active
compensating developer. Generally
speaking, this formula could be used to pull the best possible density and
contrast from negatives made in any sort of difficult shooting conditions.
The following charts
outline the chemicals, combinations, and developing times.
Please note that the
numbers in the “time” column are only a guide of where to start. Ultimately you have to experiment based on
the films used.
