Hi,
As I have been getting back my tray developing skills lately, I have found that everything works right when I use Ilford films and D-76. I can develop 4 to 5 sheets simultaneusly without problems.
I have also developed Efke 25 sheets without scratches but could not get even result.
But the Acros is different story. I have tried it with Pyrocat-HD 1:1:100 and 20 deg celsius.
By developing two or more at same time I get always markings or even scratches.
Some of the marks are like another sheet is pressed against other which has it's shape visible. Some markings are not scratches but like trails caused by edge or corner of the another sheet.
This was really surprise as I have used Acros + pyrocat-HD combination for a long time and never had any problem until now with tray development.
I also would have expected that Efke 25 would get a lot of scratches instead of acros.
Not sure however if this could be caused partially by tan process. Is the emulsion more vulnabre in tanning developers during development than in non-tanning developers?
