This was a trial to pull xtreme 400 after I shot it in my pen EE which only goes to 200 ISO on the light meter. The time should be 4'30" calculated from my 400@400 time @20C. Because my developer was warm I used the calc to give me new time of 3'. I was worried but they look great! Haven't printed from them yet but I am sure it will be no problem. Update: printed from them. Beseler 23cii condenser, 50mm f16 multigrade RC pearl paper 5x7. Exposed paper for 7 seconds, through #2 1/2 filter. Looks great.
