These are all beautiful kallitypes. Could you please tell me if you are double or single coating? I've been doing Vandyke for a while but I think it's time to move up to Kallitypes.
I used single coating with a brush. I use the kallitype kit from Wolfgang Moersch but instead of using just one part of silver nitrate and one part ferric oxalate I also add one part of destilled water which results in a smoother coating and probably in an emulsion as thin as when using a coating rod.
