We are on a private well so its straight out of the ground. For most films the development times work out to be about 10% less than recommended. The Efke for some reason gets very contrasty and needs 30-50% less with a couple of developers. I just tried some Beutler 105 and used the time for Neofin Blue. Same result, unprintable on #1. Fortunately those were just tests. That developer should work with shorter times. With the D-23 1:1 for 4 min with a 3 min. borax post-bath I'm getting about an EI of 16. The tones are very nice. Sharpness may be suffering as Mark said but its hard to tell with a Summitar hand-held. Perversely I use my better glass for high-speed film. Shorter exposures are an option but I hate to lose the shadow detail or have the highlights block up if I overexpose. I'm wondering if there is some difference between the old and new batches.

I'm sure you're right that it could be some difference in technique--perhaps we meter very differently. OTOH, could it be the water? I live in Brooklyn--N.Y.C. water is very soft--low mineral content. I know I SHOULD use distilled water, but I'm lazy and AFAIK have managed to avoid major problems with tap water. Hard tap water may give very different results.

I was printing on a 1 1/2 filter. 9 minutes was off the chart. I'm currently using the 1:1 for 4 minutes followed by a 3 min borax bath. The tones are very nice but I'm running at EI 16. Other films in this same soup seem to need a lot more time. I suspect our differences could be due to technique. Some like Tri-X at 800. That works but you have to be careful not to overexpose!

This is aprox. 20% more than the time recommended in the Massive Dev Chart for D76 and the Efke data sheet (packed with 100' bulk rolls) for ID11. Both sources recommend e.i. 50--1/3rd stop faster works better for me. I don't find it contrasty at all. FWIW, I usually use anywhere from a 2 1/2 to a 3 1/2 Ilford filter with Arista Premium RC/VC (aka Ilford Multigrade IV) in a Valloy II . As to sources, I have a few 100' rolls in my freezer, purchased from Freestyle right after I learned they had dropped it from their catalogue ( It's worth phoning--they might still have some left). When my stash runs out, I guess I'll try Photoimpex. Bob Marvin From: "Mike Durling" <durling@widomaker.com> Subject: Re: [Leica] If you had only one B&W film/developer combo, which would it be?

How long do you develop in D-23 and do you use it undiluted? - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
