Exactly. Nobody asked you to act as forumpolice. Even more so, that it was nothing wrong with that link. Dont know where you see a trick. So it was no need either.

Re: Use of X-ray film: technical discussion with example images
Hello,
I use Agfa CP-GU. I shot some sheets so far in order to find a good EI/developer combo. At the moment I'm around iso 12, developed in HC110 1+63 for about 4.5' at 22°C, continues agitation with Cibachrome drum. The density is now quite good but the contrast still too high. Any suggestion to get a softer contrast?
Thank you
-
Re: Use of X-ray film: technical discussion with example images
Roberto i tried this Agfa at Iso25 + caffenol C at 22C /agitation every minute for about 8-10min.
That gave me good density and mid to low contrast.

If you want to lower the contrast via developing you have the following options:
Drop the temperature to 20 degrees Celsius (or lower).
Less agitation.
Try a higher dilution f.i. 1+79 or 1+100.
I have no experience with the Agfa film but made good ones with Fuji and Kodak and HC-110 1+63 with this.
Usually I am working with ISO 25 to 50. If I recall correctly there is quite a drop in contrast between ISO 50 to ISO 25 so ISO 12 should give you quite a soft one.
Hope this helps.
-
Re: Use of X-ray film: technical discussion with example images
Thank you. I found a good way of avoiding scratches by using the cibachrome rotary drum. The point is, agitation is continuous. I'd try to increase the dilution to 1+79 and eventually to lower the temperature to 20°C. I'll post some pictures then.
-
Re: Use of X-ray film: technical discussion with example images
Sure, Roberto. I guess you can achieve a lot via the temperature. I work with 20 C all the time and use your times for ISO 12 too (HC-110 1+63, 20C, 4:30 min).

What ISO would you rate this X-ray film at - as a starting point? I can’t find my notes from when I was messing with this previously. It is a single sided emulsion - I believe it is for mammography.
And any advice on development times would be great too!

I rate this from 25-100 depending on the light. More red, lower EI. This should also depend on your developer and procedure.

Thanks Jim - I have a few sheets drying now. First two I shot at 50 and developed for 5minutes in HC110 (b) and 2 shot at 80 and developed for 4.5minutes. I reduced dev time for the second ones because the first two looked very dense.
We’ll see in the morning how they look dry.

Here is the best one - all quite dense. This one was ISO 80, HC110 (B) 4.5 minutes...

Re: Use of X-ray film: technical discussion with example images
Anyone know where I can still find single sided X-ray film? It looks like the Carestream eb/ra I’ve been using is no longer available. I wonder if this would be a possibility if I can find it in stock?

You can use any mammograhy film, like Fuji and Agfa. I think these are the only ones still being produced.
I have a source in Germany, if it is of any help: https://roentgenexpress.de

Back when I wanted some Carestream mammo film I got it from Z&Z Medical. The Carestream stuff is gone, but I see they still stock Fuji and Agfa mammography film. Looks like the Fuji stuff is also sold in single boxes.

And no, I don't love it. Yes, I've burned through several boxes of the stuff, most of it 8x10 cut down to 4x5 for various exposure and development tests, so I'm not just talking out of my @$$ either. My film doesn't have to be premium; Fomapan is plenty good enough for what I do on sheet film. I keep around a box of 8x10 carestream because I might want to use it for some graphic arts application some day. No way I'm wasting any more time loading it into actual film holders!
YMMV of course and everyone's entitled to their learning experience. I consumed mine, paid my dues and moved on.

Are you using trays to process? If so, flat-bottomed are the best. I use them for double-sided green lat xray. No scratches.

Here's a box prolly expired I have 500 sheets, which seem to age okay. About 30 cents per sheet 100 sheets. I'm using D23 and Microdol-X. I have a bunch of 18x24cm holders which work well

Yes, this shot was tray developed in the kind that has grooves at the bottom. I think I'm a bit rough with the cutdown process. I don't have any flat bottomed trays but I can stand develop in a yankee tank (I did it yesterday, and I don't *think* there were any black scratches...) Thanks!
-
Re: Use of X-ray film: technical discussion with example images
What I’ve done in the past is use a full size sheet of wasted film, ie bad exposure, blurry shot or even just a fixed 8x10 blank on the bottom of a grooved tray. This keeps the cut down film from touching the bottom and causing scratches. Works great and it only costs a sheet of film.

Re: Use of X-ray film: technical discussion with example images
I'm still only about 80 pages in. But quick question - how much developer is needed per sheet? Is it just as much as pan film ie 25ml of D76 per 4x5? Or is it twice as much due to the doublesidedness? Or is each side 1/2 as effective as I've been reading some are removing the back, but losing density?
I'm currently messing around with stand development in a Yankee tank because I'm showing my 4 year old how it all works and I'd rather not splash in trays nor do I think she has the attention span for that. But if its 50ml/sheet, that's only 4 sheets I can develop at once for 1:7. I'm hoping it's less.
Forgive me if this in the thread already, I tried a search but nothing came up with my keywords. Thanks!

should take the same amount of developer to get the same amount of silver at the end. maybe more fixer.

Re: Use of X-ray film: technical discussion with example images
I use 1/100 Rodinol 10 ml per 8X10
I use one gallon gas burst or trays
It needs as little as 7 min but is fully exhausted at 20 min
Try 25 ASA but it depends on color of light
I use very dim RED LED SAFE LIGHT bounced off ceiling
I also cut it to any size

Re: Use of X-ray film: technical discussion with example images

I recently read somewhere that double sided has MORE silver than normal film
BUY NOW

I’m rating Kodak S/Ra at 125 developed in pyrocat m with sodium carbonate. I have tried several brands in the past (Kodak, Agfa, Konica)of green sensitive x-ray I feel like they are all pretty much the same. Here are a couple recent ones where I tried stand development but definitely created some uneven areas.

Re: Use of X-ray film: technical discussion with example images
What you guys need for this misguided scheme is a proper low contrast developer. Trying to mangle x-ray film into half-barely acceptable tone reproduction using general purpose developers, nonsense Cookbook concoctions, stand development etc. is not the way.

Re: Use of X-ray film: technical discussion with example images
Fair enough. Apologies for my strident post. I just really, really don’t understand why anyone would use large format x-ray film, especially double-sided x-ray film (unless of course they are using it specifically for its inherent characteristics/properties, in which case I have no argument against it).

Prices have changed, of course, but back when I bought a ton of 8x10 x-ray film (Fuji HR-T, which I used on the shot above) I paid about 20 cents per sheet. I also last year bought 14x17 x-ray film for $1 per sheet. I think that's a pretty compelling reason. It's also great for learning/practicing.
My best results were obtained by stripping the rear emulsion using bleach. Ultimately, that was a LOT of trouble, and I stopped doing it but it did work well for pictorial use. I will do some more x-ray film in the future, such as that 14x17 film.
I also did like the glowy look of the film sometimes.

Hi Andrew,
I have Kodak 8x10 hangers in a 1 gal stainless steel tank. So orientation when developing was horizontal. Just experimenting really, my mix of of pyrocat was 25ml Sol A 125 ml Sol B and 3850ml of water at 68f. Left in the tank for 15 min with agitation was at the beginning middle and that’s it.

Some of us are interested in experimenting, some can’t afford the cost of a box of ilford 8x10 or the like and shoot as much as we like. 500 sheets of X-ray is about the same as 1 box of 25 sheets of ilford fp4. Not to mention the high contrast of x-ray works beautifully with alternative processes and also has a different look than modern film. Whatever the reason I don’t think it’s fair to criticize someone for doing something they enjoy and is also harmless to you.
