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.
