Re: Xray Film and Pyrocat
Many X-ray films are inherently high contrast, because many specimens for X-ray imaging give low contrast. However, x-ray films vary a lot, in terms of the type of radiation to which they are optimized, speed, contrast, etc. so you might want to look for suitable film (if possible). I could repeat general guidelines like reduced time, increased dilution, etc., but trying to reduce film contrast this way beyond what the emulsion was designed for very often results in the cost of poor Dmax, lower speed, strange tonality, etc. -- Ryuji Suzuki http://silvergrain.org From: Sandy King <sanking@clemson.edu> Subject: Re: Xrya Film and Pyrocat Date: Tue, 07 Aug 2007 21:59:54 -0400 > Hi, > > In my previous message I absolutely ignored the fact that you > mentioned you were working with x-ray film .
