For the first time I tried extended development and reduced agitation with a roll of 35mm HP5. Exposed at box speed and processed in Rodinal 1+50. Development was 25mins and with 15sec intial agitation then 15secs every 5th min. The negs are of a softly lit misty woodland and they look v.good and printable, all except for the overall base fog that seems a bit on the high side. I donít think it will be a problem to print through but is raised base fog normal for this process?
