The only time I tried to enlarge onto an X-ray film I couldn't get the exposure short enough and was not sure I wanted a slide with a blue background badly enough to justify using more film.

I had the same problem to start off, just had to adjust the fstop to a smaller setting and let out less light. I think my main reason was to turn a magic lantern positive image into a larger negative for alternate printing. Hopefully the image above proves it can work for Kallitypes
I just went through the alternate printing thread and saw one you did (van dyke brown) of an axe or cleaver on a block of wood, the detail is amazing! Great Print!Quote:

Thanks! But I have to admit that that print was from a digital negative (although the original capture was on 35mm p Pan F+). The few enlarged xray negatives that I made didn't yield particularly impressive prints. But that was also because I reversal processed them (so negative - negative) and that introduces a whole new set of parameters to control.Quote:

Hello
I've been lurking around here for a couple months and was wondering if anyone uses Sprint Developer? I'm in college and Sprint is provided. (I can use other developers if approved by faculty) I am mainly worried about how much grain. I'm not a fan of noticeable grain. I am leaning towards CXS Green but would rather Ektascan because antihalation. I plan on doing different types of alternative process contact prints.
Grain won't be an issue in a contact print. You may have to experiment to get development times.
I had not ever heard of Sprint developer and looked it up online. Fascinating. Not my thing... I'd never choose an all in one system like that, but I can see the attraction for a school lab. But they lost me when saying N+1 development was a "general safety factor." Sigh.Quote:

Slow is ok, but given that x-ray film is a bit prone to high contrast already, I'd be concerned about the contrast. Grain is probably less of a worry. The grain in my Rodinal (a notoriously grainy developer) processed 4x5s on green x-ray doesn't seem problematic to me until the print is enlarged to truly enormous sizes. If you're contact printing it will be a non-issue.
Give it a shot! It will be fun. I'd try diluting it heavily though if your lab is using it one-shot. If they are replenishing and you can't dilute it, you may need to try a water bath alternation if your contrast gets out of control. But you may need pretty extreme contrast depending on what your alt-process is? My experience is with fine silver printing so I can't speak to that.
Definitely take the time to profile your film, developer and paper (or paper equivalent in your process). It will save you a ton of time in the long run. I messed around for way too long before formally taking test shots and doing it right.
