Empty Shop 3

This photo came back from the developing lab a few weeks ago. I had 3 or 4 images similar to this and can’t work out what has caused the effect.

I took the photo using TLR Haking’s Halina 120 film camera and it was only one roll of film in the batch that I sent to be developed that was affected like this.

This week I’m posting  a poll hoping that somebody might have  some answers about what’s caused the problem. Thanks!
