Hi all,

I did read Edge of Darkness and tried Barry Thornton two baths developer on HP5+ EI400 in 120 format last week end.
What would happen if i let the film longer or less time in each bath ? Would the highlights raise higher like in a normal developer ?

What time of development do you suggest me please for HP5 rated at 400, and for 200isos ?

Best regards,
Lionel
