This afternoon a good Flickr Friend of mine sent me a panicked email:
“I recently gave an ilford HP-5 for development at my usual photo studio. I used my regular camera and clicked a model’s pics in low light with flash. The problem now is that the studio says that I do not have any images on the film at all! It is totally blank after development! Another roll used on the same day, however has images. Any clue? I don’t know if the studio is responsible since they do film development for me very regularly and I have had nocomplaints so far.”
I think I found a way to tell if the studio did screw up. Can you?
