What went wrong ?

Hello everyone,
I've been testing playing around with Exa 1c these days and just got some rolls back from the lab. The first one was fine (even if not super sharp hehe) but the second one came back like you can see on the photos attached. So i was wondering if its only some kind of light leak defect or if there is some processing mistake involved ? film was vision 3 200t. Thanks for the help

Photos can be inserted into posts; it's more convenient. Here's the ones you linked to:




You have some pretty dramatic light leaks going on. The fairly sharply defined vertical pattern suggests they happen in the camera. The most likely area is somewhere around the take-up spool; popular failure modes are decayed foam light seals.
