I am going to run some tests soon but there was something wrong and I hope the fellow apugers can help me out. I shot a roll of hp5 at iso 640. Developed it in hc110 dilution h for 15 mins at 20c, which the recommended time for dilution b is 7.5 minutes at 20c for hp5 at 800, I doubled that time to get the time for dilution h. The agitation was once every minute. The negatives that I got were very light, or very un dense. The thing that I can’t understand is how could the negatives come out so light/un dense when I shot it a 640 and developed with a common time for iso 800. The negatives should be denser. Here is a straight scan, I did not let the scanner do anything. Any hints or help would be great, thank you. I would using a incident meter and was metering for the bright side of the face to get acceptable shutter speeds. Would that been enough to make the negatives this un dense? I hope the problem was my metering because hc 110 is very nice to use.
