Thanks a lot everyone. I might try the 5um filter first then have a look at the results. If it's only the final rinse of a film I'm using it for then I can just re rinse with distilled if I get marks right?
Although the rest of the house (apart from kitchen cold tap) is bore water, maybe I should use filtered rain for everything darkroom...
I used roof-collected rain water in Comboyne, NSW...filtered out the big bits with a couple of filters used for milk. I was on a dairy farm -- developing 4x5's in trays in a no longer used house, so there were more larva, etc in the tank than down at the main house. I had to stop for awhile after mid-night when a thunderstorm moved through. I was not light-tight enough for lightning flashes! I was developing negatives from 5 months of bike-touring in NZ. I did not want to 'flash' any of them!
I mixed all my chemicals up with the cleaner water from the main house rainwater tank. The farm pumped from the creek for non-potable purposes.
Some of them came out okay...
Truman Cove, 1987
West Coast, South Island, NZ
Tolaga Bay Wharf, 1986
East Cape, North Island, NZ
Both 16x20 silver gelatin prints
What an extraordinary thread...
In Bermuda, and a few other islands around the world, rainwater is all they have.
If you have an older freezer that requires regular manual defrosting, the ice is
frozen condensate...about the same as distilled/rain water...mineral free, anyway.
Very nice Vaughn. Although our conditions may be a bit better than your abandoned farm house we do still get the odd wriggler in our drinking water. Tastes better than the bore water for the shower though!
The so called distilled water from solar distiller is a joke, probably You are referring to it?

That's the closest to pure water, in the purest sense, and will guarantee constant results in the darkroom.
Correct, the distilled water is the only military grade water.

That how everybody else figured out the water factor and had their a-ha moment.
And everywhere else. Where else does tap water come from? (apart from de-salinisation plants!).

There is limestone in the water, it collects on the bottom of the kettle, white powdery scale that just rinses away with a good sloshing.
Will this stuff get on my film? I'm just getting ready to develop my first rolls since being here, and I don't want to damage them. Maybe a final rinse in distilled?
The emulsion swell with chemicals + the junk there is in the water during dev, stop, fix and its questionable how well the distilled water would wash by itself. You might need an alkaline wash aid in the final rinse to make it more effective.
