Ed: try using DD-X at 1:8 or so dilution rather than the specified 1:4 and working up a suitable development time for that dilution. That may allow Delta 400 to retain its shoulder better. Around 1.5X the 1:4 dilution development time is a reasonable starting point.(posted 8231 days ago)Daniel: I too found many of Ilford's recommendations for Delta 3200 and/or DD-X to have no apparent connection to reality.
