    Is this caused by condensation?

    I'll make it short. I developed a roll of film and found weird streaks on some frames. I did everything as I always do, only this time I was in a hurry and grabbed the roll right from a freezer and held it in hand to warm it up. I attatched a couple of examples. Is that what it looks like when there is condensation water on film?

    Do you use the "swirl" method of agitation when you develop or do you invert the container?

    I use Patterson style tanks to develop and I used to use the little handle that you stick in the top of the tank and turn back and forth to swirl the film in the chemistry. I would occasionally get "comet" shaped streaks in my images when air bubbles stuck to the film.

    Changing to inversion style agitation, turning the tank upside down five times within five seconds made this problem disappear.

    Also, making sure you tap the tank on the table top after every agitation cycle will dislodge any air bubbles that remain on the film.
    I have a little habit. I always tap the tank three times for good luck.

    I haven't had a single problem with air bubbles on the film since I started doing these things.

    What kind of developer do you use? From Powder?

    Shutter curtains have holes.

    Could it be static electricity discharge?

    Thank you for the replies, but I'm afraid none of the assumptions are true. I do use a Patterson style tank and swril agitation, but my tank aslo moves the reel horizontally (up and down) while spinning. I use liquid developer (Fomadon R09) so undissolved particles are not the case. And the camera I used has a horizontal metal shutter.

    Almost looks like a light leaking thru the shutter when you are advancing the film.

    I would go for light leaking thru the shutter also.

    I'd take the discussion back to condensation. Isn't it possible that condensation water drops somehow magnified the light and caused overexposure, where the water was? I shot the film at EI 50, so it got quite a lot of light.

    I noticed that it is Lucky film - you haven't had any issues with the film before this? Could be a defect in the emulsion or possibly condensation, as you suggest.

    By the way, the right one, isn't that the theatre in Tartu?
