Thanks all,
I’ll certainly do some tests first and probably start with 4 sheets rather than 5.
Jim Galli, when mixing HD at 2:2:100, how do you calculate times compared to 1:1:100 dilution? I was thinking this could be a good way to go too in order to combat exhaustion of chemistry, but don’t know where to start with regards to time. I’m currently using HP5+. Does Sandy give a formula for this?
EDIT: In an effort to find this out for myself, I revisited Sandy's article on The Unblinking Eye: https://unblinkingeye.com/Articles/P...at4/pcat4.html
Looking at Figure 20. HP5+, Pyrocat-HD mixed 2:2:100, processed for approximately 7.5mins @ 72 degrees F. should get me a CI of 0.52, which is desirable for VC silver printing. While I trust this is a good starting point, does this sound right to you? Seems a great place to start for processing 5 sheets at a time with 1L of total working solution–so more than needed as a safeguard, rather than bare minimum–so not to overload the motor and guard against exhaustion. Sandy states that with this dilution you can get away with 20% less working solution per sheet.
