X-ray Film example and comparison.

The Fuji HR-T is listed as "High Contrast" Green sensitive. The HR-U as just Green sensitive. Has anybody played with both? The HR-U I just shot seems plenty high contrast but I overdeveloped it and haven't stripped the one side yet.

I didn't realize there was an HR-U. They don't sell it on cxsonline apparently. But I guess the Rodinal keeps the contrast controlled because I never have problems with contrast. It's too little contrast sometimes if anything.

http://www.zzmedical.com/zencart/xray-film-c-28.html That is where I found mine. Shipped fast and no problems.

I think if I get a chance I will cut up an 8x10 sheet into 4x5's and do a better job of testing. I stick to HC-110.

Corran, I noticed the shot with your wollensak wide angle looked really nice with lots of detail and that large neg look...

Thanks, but I've cropped about 15% of the edges to get rid of the corners which were atrocious...I might've had a dud because my 159mm just never sharpened up in the corners even at f/45.

Well, there's nothing like putting a theory to practice that shows what a bonehead you can be.
Does anyone see where I went wrong in my last statement above? When you contact print the original to make the unsharp mask, the resultant mask it a positive!
My X-ray film "unsharp mask" is a negative just like the original. Actually it is just a copy... Nothing else.
As suggested by others the secondary image might be good as a selective mask to dodge or burn in an area. Or as a spotting mask. But it's of no use as a contrast mask.
Thanks for tolerating my well intentioned but miss-guided idea.
Bill (back to the drawing board)

There must be some advantage to messing around with one side emulsion. Wouldn't it change neg density so you can have selective contrast by bleaching away certain areas for higher tones? Just an idea...

Does anyone know where I can find a list of single sided X-ray film?
Thanks,
Jim

I think the answer to that is buried way deep in this thread. From what I've been able to gather, single sided films are only available in odd sizes and are way more expensive than ordinary double sided medical films. Examples would be mamography films and industrial films for radiographing welds and metal parts. My own experience is that emulsions on both sides isn't such a bad thing, but I haven't tried any single sided films.

I seem to recall that there was some 8x10 single sided green sensitive. But it's a search finding it in the thread. Probably easier to find it at the supply houses.

It's true the single sided was way more expensive for some reason unfathomable. And the reversal duplicating film was expensive too.

If you're looking at those you may as well look at Ilford. That's superb film for little extra cost. Or some of the other "real" camera film.

The cheap stuff is the double sided xray film.

I am really surprised about the fact that single-coated X-ray film is so expensive in the US. I live in Germany and get single-coated X-ray Film (for mammography) at an approximately 40% higher price than double-coated usual X-ray film (43,00 € to 30,00 € for 100 sheets 18x24cm). The only drawback is that only metric sizes are available here so I had to purchase some extra holders just for this specific film.
