That's what I was thinking but wanted to confirm.
Also going longer than my usual 2.5 min. development
might help bring down the blacks as well and give more
apparent contrast.
What's the difference between using sodium hydroxide
and sodium carbonate in the end result? How much
more additional carbonate is suggested for a starting
point if I were to go that route?
Thanks for the suggestions!
