I found something else on my film today that I can't explain. This roll was shot to test out a new lens so I'm hyper critical about things I dont understand. Please look at the left side of this image. There's a big blob of something that I cannot really explain. Is this possibly related to all the lens flare seen in the rest of the image? I have my doubts about that. The negative just shows a big large black spot on the left side of the image. Thank you for your help!
