An
Aid to Assessing Filtration Changes
From
Bill Broadhurst Area 3+
Thank goodness that the CRC does not
confine its self to colour reversal matters only. For some years now I have
been grateful for that simple formula for EP4 and now we are offered C 41 in
2 bath form in the latest News Letter.
I have used the Leitz 2 bath for black
& white for many years and have found it excellent in both performance
and economic keeping qualities. So would the same things apply to C41? Well,
I mixed the solutions with my usual care and followed the development
instructions to the letter. Exposed a short length of film and developed it.
Disaster.
The leader showed a little density and
there were a few spots where pictures should have been. So, considering the
situation my suspicion fell on the temperature given. Twenty degrees is a
long way from the usual 38 for colour materials, better try again using 38¦.
Brilliant! My test shots included indoor shots with a window frame dividing
the frame so that I was including the shadow area at the side of the window
together with the garden outdoors. There was detail in the shadow and in the
high lights equivalent to a carefully placed fill-in flash. Another shot I
took from inside my kitchen door because of heavy rain, 9 o'clock on a
November morning, exposure 1/15 at fl.9. My non-photographic wife commented
that she would not mind seeing the picture as a calendar.
Was 20c a misprint or have I gone wrong
somewhere else? I don't know but development at 38¦ will certainly be my
method in future. Long live the CRC diversification into other aspects of
photography, for while I am a considerable user of E6 I have use for colour
neg. for the family snaps.
