Last week I was trying to rush through a roll at lunchtime, and after finally getting the hang of spooling Rollei Pan25 in the dark, when I went to add water for the presoak, I opened the top of the tank just long enough to see the spool before I slammed the lid back on.
The room was pretty sunny, and I was close to tossing the roll in the garbage. I continued on mostly as I obviously need more practice at this.
I was surprised that I had images, and a couple were good (by my admittedly low standards). I am sure if this was a fast film I would have been done for, and maybe those new low UV transmission windows helped a bit.
Here is an example of one that still had some usable image even though a bit got blasted, and one that survived mostly intact. More images on Flickr http://www.flickr.com/photos/ieblog/...7623540717077/ (all those labeled Rollei Pan25 were exposed to this particular error).
