Re: [Leica] Ilford Delta 3200 @ 1250. What have I done?

Hi George:
I would like to refer you to a website that I refer to frequently for
processing times/temps.  It is http://www.digitaltruth.com

I just complete a roll of Delta 3200 exposed at 1600 in Xtol 1:2/68c/17
minutes.  I used the times from digital truth and they are perfect.  They
were taken with a Contax G2 which may account for their sharpness and
exposure accuracy.(just joking!).

I am looking at the digitaltruth sheet on Xtol and there is not a time/temp
for 1250.  However, in referring to processing information using FULL
strength Xtol at 800 and 1600 there is only 30 seconds difference in the
time.  So, it appears to me that 6 minutes and 15 seconds would be the time
for Delta 3200 @1250.  Not much margin for error is there?   These time/temp
match Kodaks recommendation.

Processing the Delta films is so easy that I would never consider allowing
anyone else's hands on them.  It has been my experience that once you have
relinquished control of the negative you have lost control of your exposure.
I know exactly what goes into the tanks and I never repenish any chemicals.
I also use distilled water to mix the developer and I make sure that all
chemicals and water used in the process are the same temp.  I am anal about
it but I do get beautiful negatives.

I will keep looking for the data for you but it is my guess that there is
very little time difference between the processing times for ISO 1600 and
1250.

Bob
