    Re: Images shot on X-ray film

    Here are some shots on "green latitude" film.
    All scanned. My darkroom is only usable after the sun goes down, so prints are rare.

    The 2nd one shows the effect of overcompensating for the uber-contrast. I'll post some actual prints next.

    The brownish one is a scan, the other a silver print.

    again, brown -- scan, other -- silver print.
    This silver print was done on VC paper with a 00 filter and alternating Dektol 1:3 and water bath -- in other words, it was really hard to get it to look like what you see. The contrast was just about uncontrollable. Also, I'm not a very good wet printer .

    Re: X-ray Film example and comparison.

    Question: How finicky are holders for nominal film sizes? Mammo film is available in 24x30cm, but not 10x12". How close is close enough?

    George, you're stripping the back emulsion, right? Great scans you're getting.

    I was on an airplane to Australia that showed the remake of the Little Rascals. Painful experience...I don't want to talk about it...

    No, those are not stripped.

    But, here is a "before/after" example -- before on the left, after on the right. As you can see, the striping took away about 1/2 the density, which was not a good thing -- the result is now an underexposed neg. Getting any character in the window over her left shoulder introduces really ugly grain now. My next attempt at exposure/dev/stripping will have to keep that in mind.

    I might try the film at ISO 80 and stripping that. All of this is really worth the effort if you're going to shoot with old soft focus lenses as they were designed to work with older film, and I think stripped X-ray film acts just like the older stuff.

    Re: X-ray Film example and comparison.

    Gotta do your own homework on that one, probly. Close enough for hand grenades surely.
    But 10x12in is 25.4x30.48 cm so it doesn't sound all that close to us former engineers.
    Now if there is about that much extra space in a 10x12 holder, you might just have a serendipity, by not having to sliiiiiide the film in, but tape it at the edges under the safelight. no wait, set it under the thingy on one side and get more tape room , less tape on the other. [ that's my fantasy plan for a 14x36 inch holder -did I say fantasy?]

    Are Foma X-ray films available in the US? They have medical (including mammo) and industrial types: what is the difference?

    Re: Images shot on X-ray film

    George,

    I stripped my first sheet of X-Ray film, using soapy bleach and a foam brush. The sheet was developed in a tube with rotary agitation, and the results are very good, but next time I'll develop more. The phrase, Gamma Infinity comes to mind. My first sheets of X-Ray film were exposed with my Verito, and a print from one of them hangs on my wall.
