what about devleoping and stopping and drying (in the darkest spot you can find), rolling it up, putting it in your luggage, then fix it when you get home?
OP: have you considered carrying a few bags of powder DF96 monobath in your checkin luggage when you travel? Apparently, the powder kit doesn't have travel regulations applicable to it.
Well, if you can develop the film before you get on the plane, what about devleoping and stopping and drying (in the darkest spot you can find), rolling it up, putting it in your luggage, then fix it when you get home?
my guess is the radiation from the X-ray or CT scanner would re-expose all the film and solarize it. if it isn't light safe its not safe to any sort of light..
fixer removes unexposed silver that hasn't developed so if it isn't fixed it will still be able to be exposed like any other silver on film or paper wouldn't it ?It won't be redeveloped - it'll just be fixed. The only thing to do is test the idea. And that's all it is - an idea.

that is what sabattier / solarization is all about, and even if it isn't re-developed it will be fogged, and I have never been able to remove fog with fixer, because it's toasted ,, might be good film use for an experimental art installation.

I'm not sure about the dried part
Sorry, my response wasn't clear.I wouldn't want to leave film wet for an extended period of time, that's why I'd dry it. Also, you'd need to roll it back up to store it.
Intriguing, but also an almost guaranteed way to get you kicked out of your hotel room!Has anyone experiemented with making fixer from onions?

No, probably not something you can carry out on the the warmer plate of the hotel's coffee machine (especially not the crappy little single-filter ones they have now in American corporate hotels, which don't even have a warmer), but perhaps still a little more accessible than finding a pool store and buying several kilos of chlorine reducer.
What I'd hypothesize as a starting point would be to extract the juice of onions, or boil them, finely divided, in water, add sodium or potassium hydroxide to cleave off the organic group from the thiosulfate (it seems the sodium is on the other end of the thiosulfate group, and in any case will separate in solution due to ionization). What I lack is knowledge of how then to separate the sodium thiosulfate from the organic. A hydrophobic organic solvent, perhaps, like toluene? Or perhaps the organic (propane or propene?) will simply evaporate off, being insoluble in water? Once the organic fraction is removed, it should be easy to neutralize the solution with a mild acid and evaporate the water to give a mix of sodium thiosulfate and the sodium salt of whatever acid was used.
I should have said "I'm unsure what the best way would be to go about the drying part".
excellent ! I saw your results in that thread and was hoping you were going to chime inYou have to make a super saturated solution of salt in distilled water but it has to be iodized salt. I fixed for 48 hours agitating every few hours when I was awake. I have heard of others doing it for 24 hours. I did this about a decade ago and the negative still looks good.
Ding ding ding! Was going to .. we’ll you already didNo, but I chopped up a whole bunch of shallots and soaked them ( skin and all ) in IPA for a few weeks... hoping to see some reversal like @darkroomexperimenter saw when he developed film with shallots. I wasn't able to reproduce his result.
When I travelled with cyanotype chemistry I was told to have them in sealed well marked containers…. Fixer rice would be easy to seal and label even with a photo from the internet saying” hypo/ photograph fixer “. Less problematic than half processed film or stinking up a place with boiled onions and garlic.. unless the garlic onions could just be mincEd and smeared right on the filmthink if you have commercially packaged powder bags
This evening I tried out Caffenol for the first time, developing a half-roll of 14-year-old frozen FP4+ in Caffenol (reduced carbonate version - 40g/l Sodium carbonate monohydrate, 16g/l Ascorbic acid, 40g/l disgusting cheap instant coffee) with a water stop and normal rapid fixer. The wet negatives look surprisingly good, better than I expected for this "supermarket developer". Tomorrow I'll process the other half roll in my normal Pyrocat-HD 1:1:100 and make some comparison prints next week.
This got me to wondering - has anyone has ever tried making a "supermarket fixer"?
There’s no need to get all complicated about it.
(1) You're quite plainly wrong. Sorry. Look it up.
(2) Not thoughtless. Developed, completely stopped and dried but unfixed films can stand a bit of light without any significant fogging. Give it a try.
(3) So you likely wouldn't use coffee and vitamin c to develop them - neither would I. I'd just mail them home, if I was worried. If I wanted to develop them on a trip, I'd pack dry fixer. But those aren't answers to the original question, are they?
It's straightforward that there are sensible ways to deal with the situation. But sensible isn't always interesting. You have to admit there would be a bit of adventure to using coffee and onions to develop your film. Anyone who would use coffee as developer has clearly left sensibility behind, anyway
