Eric, It has been many years since I used it too. When Ilford was sponsoring our workshops, I used it and was happy with the results. It do recall it not lasting like my old friend Ansco 130 though, so my personal work was done with 130. I did use the Ilford in my ICP processor though.

Perhaps a false economy indeed, but along those same lines, I do get good blacks in Ansco 115 diluted 1:5 but developed for 2-2.5 mins. Certainly as black as needed anyway! :) So perhaps for RC prints, which is a relatively quick development, 1:14 would be fine but there won't be much more of that done here anyway. Thanks Richard. e I am pretty sure the RC papers that develop quickly have developer-incorporated emulsions. This was originally to allow the paper to be used in an activator type rapid-access machine. I am not sure anyone uses these any more but I think some RC emulsions still have developer in them. The developer-incorporated papers develop in about half the time of a conventional emulsion weather coated on RC or fiber paper. Most conventional papers take somewhere between one and two minutes for complete development. The cold tone papers like the late-lamented Kodabromide, would develop in one minute, warm tone papers took about two minutes. These are minimum times and extending them by about fifty percent was common. Development time can compensate for exposure over a rather narrow range. Despite the extensive literature on control of contrast by development the contrast of paper is pretty much built into the emulsion so that variation of exposure and development has very little effect on it unless one is willing to accept under-developed blacks. This is a different situation from pictorial film where the emulsion is seldom developed to "completion", as a result one can vary the contrast of the image over a rather wide range by adjusting exposure and development. I rather think you already know this stuff but some readers of this list may not. -- Richard Knoppow Los Angeles WB6KBL dickburk@xxxxxxxxxxxxx ============================================================================ ================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
