I had no idea about this film until I opened my Horizon to load it and HEEEY THERE IS STILL A FILM HERE OMG OMG OMG!!! That explains all the light leaks and lost/cut pictures.
Since I did not remember what was in the film, I decided to push it to 400 because the pictures I had taken the other pictures in Brazil on a really dark and bad weather.
When I scanned the film I realized that these pictures were taken on a very sunny day on my last trip to Argentina. I think I lost a lot of color by having this 100 film pushed to 400 with pictures taken on such a bright day. But oh well, that's la vida.
