I processed, for the first time, a roll of Efke 25 35mm film last 
weekend. Because of my unfamiliarity with this film, I ran off 15 
exposures,  six blank frames, and another 15 exposures, then 
processed the first set of exposures with 5min in 1+4 TMax developer 
at 20C and the second set with the 2-bath compensating developer I 
generally use for TMax (Barry Thornton recipe). With the first half I 
also did an initial 1 min soak in water and a brief stop bath of water 
between developer and fix, as recommended by the film's suppliers 
(JandC Photo).
As I was about to do a "finger squeegee" with the washed first set, I 
noticed light marks on an unexposed part of the film that clearly had 
come from handling this part of the film. Running my fingertip 
deliberately across the same area caused more damage. 

The second set of exposures, processed in the 2-bath developer, 
didn't have this problem and I could wipe unexposed areas without 
harm. Both pieces of film seem to be well developed and I don't notice 
any pronounced differences between them, apart from a slightly 
greater overall density in the TMax-developed exposures. Grain 
structure seems similar in both though differences may show up when 
I do some printing.

The first half of the film was processed in a Nikor metal tank, the 
second half in a plastic Paterson tank; I can't believe that this would 
have had any effect on the processing. Could anyone suggest what 
might have caused my different results with the two developers?
