• Finally rinse with a few drops of ILFORD ILFOTOL Wetting Agent (1:200) added to the rinse water.
It is good that this final rinse is made with distilled water to prevent drying marks, that water (with wetting agent) can be reused many times, so instead domping it we can keep it in any bottle. If out tap water is high in salt content then this way is specially interesting.
Fortunately where I live we have a very clean water. I'll try the tap and distilled water to compare it. Thanks!
Have just processed 5 rolls of 120 film this morning and as I was washing them I started to think about the amount of water I use when printing and processing my B&W work.
Water restrictions are coming into effect yet again in South Australia this summer (and also over this past winter!!) and I want to reduce the amount of H2O I use as much as possible. I do use a print washer, but even then it seems to use copious amounts or am I imagining things??
How do you wash your prints and films to use the least amount of water possible?
Does someone have a reference for the Ilford water change method? I can't find it on the Ilford site. Thanks!
So, I've been doing the Ilford method for years (or a modification of it - in total, 9 to 10 water changes). I think I use about 5 to 6 litres of water to wash a roll of 120.
The main reason I use this method is the water temperature in my laundry is too variable. This morning (Australian winter), the water was coming out at 14 deg C. In the dead of summer, its not uncommon to see what coming out at 26 deg C.
But doing this wash method can become a bit of a drag if you have a full day processing in front of you. So, I've been thinking of building a tank with a small pump to do the final wash.
If I read the Kodak literature for film processing, they suggest washing for 20 to 30 minutes, with a flow rate that changes water every 5 minutes. So, If I wash in a 1 litre tank (which I typically would), I am assuming I'd still get away with less than 10L to was a film and a flow rate of around 200ml a minute.
Does this sound like a daft idea?

That is very little water, but I think it will amount to about the same if, for example, I use my 4 reel one liter steel tank:Or if you use a washaid like Kodak HCA first, you only need to rinse in running water for 30 seconds, use the washaid for 1 - 2 minutes, and then wash for 5 minutes in that 5 minute/water change rate.
On another note. In most parts of the economically privileged world, we use perfectly good drinking water in our toilets, and many people haven't changed to the most modern toilets with low water usage.
How many times does the family use the toilet in a day? There's som low hanging fruit.
Not to mention; why do we grow grass lawns where grass won't grow naturally?
Good chance that in more of the world than some want to believe, the Ilford method will be enforced by law, I'd have thought
