I have looked at both. Haven't tried sepia yet, let alone a split tone effect, so I am trying to learn. This looks as if the sepia is slightly darker and overall not quite so high key.
The differences in the processes, if any, in the two prints would be hepful. Was this Fotospeed variable and odourless sepia?
This is Fotospeed ST20 with 15ml of additive/litre. I bleach back only a little using half strength ferri with this paper, just until the characteristic straw colour starts to appear. Then its a quick wash and straight in the toning bath.
This print was given more exposure than the other one - hence the darker tones.
