Meet my family

first roll in my new Zenit 11 (TTL with lens from 11). it came out very strange. i had to do a lot of magic with my scanner to beat the best out of these crossed negatives. whole roll had this huge continuous lightleak in upper part of a strip. i have no clue what could have cause it. also in a few pictures the shutter curtain went wrong. i was worried that my Zenit is broken, but next film came out just fine... i don't understand.
