Hi Guys,

My problem are blue horizontal stripes comin up on photos ocasionally.. or ever comin up on the majority of the photos. It's my first film made with Zenit 12XP and I am kind of disappointed. Please see the attachments and kindly advise:

Bad light:

Photo24_4.jpg
Good light:
Photo22_6.jpg
Photo23_5.jpg
Correct ones:
Photo21_7.jpg
Photo27_1.jpg

I thought it may be a matter of diodes maybe.

Thank you in advance.
