I was recently gifted an old Kalimar K-90 1000 35mm camera. My first roll of film turned out perfect, no flaws whatsoever. On my second roll I took photos of my daughter, the first half turned out beautifully but the second had a "fog" to them. I'll add a picture from the roll to show what I mean.[![enter image description here][1]][1]the photos were taken in the same spot, on the same day, just within a half of an hour of each other. As I said the first half were great and the second turned out like this. My question is could I have messed with the exposure on accident? Is it trouble on my end? I'm 100% new at this, I have no experience with 35mm. My daughters birthday is this weekend and I'd love to take photos with the camera but want to make sure I'm doing it right so I don't have ruined photos. Thank you in advance![![enter image description here][2]][2]
This photo was from the beginning of the roll
