Light leak help

[chacabuco]

Hello,
Wondering if anyone here has seen this kind of a leak before. Its not showing up on all my sheets but effected a couple of negatives from my last batch.

Thanks in advance

On second thought (and with solicited input) maybe this a result of a processing error? I've never had a problem with this lab before and it only showed up on 3 out of 27 negatives....

It looks a lot more like processing to me.

If the film in the holder was cool and the air humid, you might be looking at condensation on the film surface at the time of exposure.

Well it was cold out and the loaded holders came from a heated car into the cold so maybe that was the cause. Thanks for taking a look!

[Paul Metcalf]

Yeah, condensation given the scenario you describe. Keep your loaded film holders in your trunk (non-heated) if shooting in cold weather.

Looks too localized to me to be condensation, I agree with Jim Noel that it's a developing issue
there's a link to an article that seems to exhibit the same issues due to residual photo flo
in the developing tank - http://startstudioarts.si.edu/2011/02/troubleshooting-film-series-bubbles-on-negatives.html

Well it sure looks like the view from inside my old landcruiser when the windows are all fogged up with condensation. That photo-flo issue looks a lot different to me.
