Indeed, low mineral water is a great idea.

Stick with the ID11. No need to change.If Ilford does go
belly-up you can switch to D76 which is comparable to ID-11. HC110 is OK if you're using medium or large format but 35mm shows a little too much grain for my taste. Regards, John S. Douglas, Photographer - http://www.puresilver.org Please remove the "_" when replying via email I happily stick with ID-11 or D-76; now I'm trying to make starting from raw chemicals this kinda soup. In these days i'm trying also HC110 and Xtol extensively and deeply. And I'm receiveing good results with Ilfosol-S at 1+14. thanks john. Your comments are very appreciated. -- Non è bello cio che è bello figuriamoci cio che è brutto! Ed io imparo. |

Then what could make the developments be more consistant using distilled
water rather than tap water? I would be very curious to find the technical explaination (and then save on buying dist. water...) Thanks, Emmanuel "Donald Qualls" wrote in message om...

As far as consistency, I would look elsewhere although you did indicate that you are using Xtol which is suspected to be sensitive to water quality. Have you considered using T-Max RS ?

I would be very curious to find the technical explaination (and then save on buying dist. water...) Your tap water comes from a natural source of some sort -- here in the United States, most major cities get their water from a river or lake system (otherwise from systems of wells) with considerable treatment before it reaches consumer taps to ensure the water is biologically and chemically fit to drink. Those treatments, however, don't filter out seasonal changes in water composition (in some regions, water is harder in summer than in winter, or vice versa -- I forget which way it runs), or short-term changes. There can be chemicals from farm fertilizers, upstream sewage treatment or industrial effluent, and air pollution that gets washed into the watershed by rain, iron from rusty pipes, even lead from really old plumbing (the word "plumbing" comes from "plumbum", Latin for lead) -- and if the chemicals aren't considered hazardous in drinking water, the water won't be treated to remove them. If the chemicals enter the water after treatment (as is the case with most iron, copper, and lead impurities), there is no possibility of municipal treatment removing them. Very few drinking water systems are filtered as you and I think of filtering; it simply costs far too much to apply micron and carbon filtration to huge quantities of water, most of which will be used for laundry, showers, and flushing toilets instead of drinking anyway. Distilled water is always the same, so it's absolutely consistent. Tap water isn't always the same (at least in some regions), so it can cause inconsistent development. Even though Kodak says chlorine and chloramine don't affect development, there can still be many other chemicals in water that do. -- The challenge to the photographer is to command the medium, to use whatever current equipment and technology furthers his creative objectives, without sacrificing the ability to make his own decisions. -- Ansel Adams Donald Qualls, aka The Silent Observer http://silent1.home.netcom.com Opinions expressed are my own -- take them for what they're worth and don't expect them to be perfect. |
