yes normal dektol (or I really like a product called "Ultra black", not sure if available in Europe)..

try it- the "bake-n-dip" sometimes is interesting for "high-key" images, increase paper exposure time approx. 200%, develop 5-10 sec in dektol- quick to stop bath!

However, this is something SILLY :roll: I do only in an experimental sense looking for special effects, as I said for most work I have standardized on 2 min.
