I'm sure we've probably all made this one.
So there I was, happily loading my patterson tank in the darkbag. I've got one reel loaded and the other empty on the spindle to stop things from slapping around. So far I've been using agitation with the little stirring rod thing, without inversion (tends to spill chemistry) and doing well, and the last time I did it I filled the tank half full (per the guide on the base) and got a good result. Okay, all well so far, but then I bring it out into the light and pour the developer in and start agitating away, and things just don't feel right. The sound it makes as it sloshes back and forth isn't quite so sloshy as before, and the little stirring rod thing isn't plugging into the spindle properly. Yeah, whatever, I think - I'm still new to this, so maybe I'm just not used to variability in the way things are happening. I should also add that I had had a busy day.
So of course when I finally open the lid after the fixing phase to begin the rinse, what should I find but the film closest to the lid. ABOVE the chemistry. And of course completely fouled up.
I'd put the ****** spindle in upside down, which is why the stirring rod wasn't mating properly with it, and the narrow upper part was bearing on the base, which is why the sound was different.
If I had picked that at the beginning of the development phase, I might still have salvaged things - I am in a basement room that comes off a basement room, which in turn comes off yet ANOTHER basement room, and there was still the opportunity to close ALL the doors, turn off ALL the lights, open the thing up in the dark and flip the whole shebang so that the film was below the surface of the developer, and start again. I might have ended up with an ugly tidemark, but since the primary aim was to take a series of exposures at all shutter speeds and find out the hard way how things are lining up with the metering, that wouldn't have mattered too much.
Two things might have prevented this...
1) Filling the tank full of developer/fixer. DOWNSIDE: Uses twice as much chemistry for only one roll.
2) Not putting the second reel on the spindle until AFTER I had put it and the loaded reel into the tank in the darkbag. (I usually put the spindle into the centre of the reel before I start loading, so I'm not feeling around for it.)
I will be implementing #2 as part of my routine, even if it means the darkbag is a bit more cluttered.
So yeah, when things aren't sounding or feeling right... check. I am fortunate enough to have a relatively light-tight arrangement of basement rooms, and can rectify this if I ever do it again. The alternative would have been returning the whole deal to the darkbag and opening wet chemistry inside it, which would not have been a cool thing to do.
Anything else people can think of?
