Jim Noel;649058 Black trash can bags will not block light. I once had a student who built a darkroom n her home and could not understand why her film and paper were always fogged. I took a look and found that I could almost read a newspaper in the darkroom which had these bags over the window.[/QUOTE said:Don't buy cheap thin bags - get the thick ones.
Try it again with multiple layers. It works. I've made on the road dark environments the same as the windowless darkroom at home (with no door light leaks either).
Sit in the room for a while to allow the eyes to fully dialate and watch for light leakage problems.
Black gaffers tape also works well to seal door edge light leaks - and it does not pull paint off the trim.
Good luck
You've set yourself up quite a problem. Frankly, I think you could ruin a perfectly nice trip by tying yourself down to developing every night -- it's enough of a pain to do correctly in a good darkroom, much less in improvised conditions. Also, working out of a confortable enviroment the chances of screwing up the processing will be greatly increased, not to mention making you too tired to get up at 5 AM for the "magic morning light."
I didn't read how long you're going to be gone, but presume it's the usual 2 weeks or so. That's less than a 100 sheet box of film. Chances are excellent that if you check your equipment and make a couple of test exposures before you leave, that you're going to be all right on such a short jaunt.
I'd leave the processing stuff at home and enjoy the trip. (One other option just occured to me. Allow one whole day, half-way through the trip, just for processing and relaxing.)
But how about a monobath approach with ordinary sheet film. Then I suppose you could do your processing in a large film changing tent. Just a thought.
2F/2F: I would really think long and hard about the *why* before thinking any more about the *how*.
"* Take black plastic bags (huge trashcan sized) and blue tape to block out windows for changing."
