Last night was the first time I have tried printing in over a year. My makeshift darkroom was out of commission. When I tested my paper/dev combo for max black, I had to close the lens down to f/16.5 with a grade 4 contrast filter to get the time to around 15 seconds. With Oriental Seagull FB I never did get a good time. With Ilford MGIV FB I was able to get some fairly good prints with the above set up. Should I not be able to use f/8 and still have enough time to dodge or burn? 15 secs is fine but with the Oriental paper the time was going to be in the 5-8 sec. range... Are my control elements time and f/stop? Ideas about why the time was so short?
