Re: Ilford HP5 Plus development

["Rev. Sidney Flack" <sgflack@xxxxxxxxxxx>]

Way too short, Pablo.  Anything less than five minutes gives uneven 
development with TMax.  If Trevor uses the 1:9 dilution from the syrup, 
his normal dev time will be between 7 & 11 (give or take) at 24º C 
depending upon the ph and hardness of his water source.

The 1:4 recommended dilution is too active and therefore gives too rapid 
dev times.

Peace!
