LATEST WEIGHING & MIXING - REPORT
Those
following my venture into weighing & mixing will remember that I
haven’t been having very much luck. My very first try using the BK 60
formula and some Konicachrome film produced somewhat reasonable. first
time results, but which were still a bit took ‘Green’.- Some while
later .1 tried using Ron Knowle’s two developers from his 3 bath
formula, again using and sticking to the. BK60 separate Bleach and Fixer
arid using a Photoworld Reversal bath. This produced the worst green cast
I had ever seen with the slides being of not much good. I didn’t suspect
the ‘reversal’ as I have used the Photoworld bath many times with
excellent results. However I processed another film but used 1i~ht
reversal, I was both sad to find the same horrible green cast but pleased
to prove that the Reversal bath had been fine, I would also add that I
don’t condem Ron’s formula as it could well have been my error,
somewhere along the way, and Ron has sent me numerous very well processed
slides he has done in his brew.
So
there is nothing for it but to try again. As Frank Beaumont had sent me
the Labachrome film and I was recommended to try the Arnold Moorhouse
formula, I decided to try this formula. Again just using the two
developers with the separate ‘BK6O Bleach and Fixer and the Photoworld
Reversal. I made up two 300m1 sizes of the developers and this time I.had
Tony Chuter check the pH values and as luck had it, he used the C.P.
Electronic pH meter, which proved the values to be exactiy as the formula
had predicted, so now I was a little more confident in getting nearer the
proper result. But sadly, NOT QUIT. But at last I got rid of
any sign of green cast and although the film looked somewhat dense the
more normal frames showed that the colours were very good. So I am pleased
to say that I am now Very close to my goal: just a bit more experimenting.
