I took a load of test shots around the house with my recently accuired SQ-Ai.
Tetenal Ultrafin 1+20 at 21'c for 7min, adgitate 30 seconds then 5 sec every min as per Massive Dev chart
Ilford rapid fixer
10 min wash with tap water and final dip in Photoflo
Ten of the frames were fine but one has some odd spots on it that look a bit like chemical burns. I'm still new to this could anyone shed any light on what the marks are?
