I shot some 16mm over the summer and recently had it transferred, and I noticed a few momentary spots of what appear to be light fogging on the transfer. Initially I was concerned that it might be due to a light leak in the mag, but the more I thought about it, a persistent light leak probably wouldn't result in momentary flashes of fogging. That's when it occurred to me that the flashes appear near the beginning or at the end of shots and at times when I may have momentarily removed my eye from the viewfinder, so I'm wondering if what I'm seeing is actually viewfinder flare.
I've shot a fair amount of 16mm with my SR3 and haven't noticed this fogging before, but then I realize that many factors can contribute to viewfinder flare, and it could be that on the day I was filming, the angle and intensity of the sun and position of my viewfinder were just right to cause the flare.
I've uploaded a short clip of the transfer showing two instances of the suspected flare. The first occurrence is pretty bad, the second isn't so bad but is nonetheless noticeable. So, is what I'm seeing in these clips actually viewfinder flare, or could it be something else?
Thanks for any advice!
