Started out as the other Tulips Lumen photo. I thought Selenium toning might enhance it, but it quickly took away the color. Happened so fast I couldn't save it. Just a lesson - don't Selenium tone Lumen prints.
What happens if you leave it in even longer? Or, if you sepia tone first?
For instance, lith prints from Fomatone paper turns a weird color if you selenium tone right after fix and wash. But if you bleach back a slightly overexposed print just a hair with dilute bleach, tone in sepia, and THEN selenium tone, the effect is a color enhancement.
And, Agfa Portriga Rapid turns completely gray if it's selenium toned right after lith printing. But if the above trick is applied, I can get a beautiful chocolate brown tone in selenium instead.
