   my lumen print exposures are anywhere from 15 minutes to 60 minutes. Northern sunlight is much weaker

   I live in London so my exposures are subject to all kinds of weather. I find that overcast days are better than direct sun but it all depends on the paper and the subject. I can get a reasonable image after 30 minutes but the longer exposures bring out more subtle tones in the paper.
