flare? or a ghost?

Interesting thread, Lauren!

The photos with the white marks and the curve look amazingly like an accidental double exposure...of a curved wall, dam, or something similar. I had more than my share of these until I decided to always use the same protocol when shooting medium format: wind just before shooting, shoot... and then don't wind again until just before taking the next photo. This keeps me from forgetting where I am on the film, and also maximizes film flatness, since the film doesn't sit (and relax) for an extended period before each shot.

Sincerely,

Dave
