You can try this.
In late spring some LF-people will meet again at my house, nearby Berlin, so if you are interested?
Ritchie
Thanks Ritchie; a good link there in an amazing number of sizes - but not 20x25cm for some reason. The 12x30 would give three 12x10 sheets with no wastage, even cheaper.
Though I am tempted by the possibilities of 30x90cm for some very large format landscapes... if only I had a lens with a meter coverage! (I wonder about a pinhole...)
Can't commit a date at the moment for a meeting, but please keep me informed; I'd love to meet. Life is a bit complicated at present.

Is there anybody in the UK who cuts down X-ray film to 4x5? I am interested in trying some, but no not have a darkroom to do the trimming.
If anyone can answer please send me a Private Message.
After quite a bit of prep work, we're almost ready for the expansion of our little vineyard.
I shot this picture a couple of days ago.
The sun was playing hide and seek with the clouds.
Thankfully, just before it went down behind the hills in the west, the clouds opened for a few minutes, and allowed me enough time to make a couple exposures.
I attempted to make this picture the day before, but the clouds just didn't budge.
This is my first successful exposure on a new (to me) x-ray film that I'm trying out.
It's the Agfa HDR. A green sensitive, single sided, mammography film, with anti-halation layer.
18x24cm camera

Excellent Thodoris. May I ask where you sourced this film? I've looked before but haven't located a convenient channel yet.
I found a couple of expired boxes at my local Agfa distributor. They stopped carrying it after their clients switched to digital a few years back. They still carry the CPG+ however, which is the film I've been using for years.Quote:

The first impressions are very positive though.
It looks great. Does it have an anti halation backing? I kind of miss that on my double sided film. The green sensitive stuff isn't too bad, but the blue sensitive film suffers very badly from highlight halation.
Thank you.Quote:

Thodoris, BTW that photo looks much better on my laptop than my phone! I wonder if the Agfa is available in the US. Not that I need yet another photo project!
Thanks Mark.
I could offer to send you a few sheets.
18x24cm is a weird format though. It's very wasteful to cut down to 4x5" or other "regular" sizes.
That's why I went out and built a whole system around it.
Thodoris, thanks but no thanks. If I did my math right that's approximately 7 and 5/64ths by 9 and 7/16ths. I don't think that's going to fit in an 8x10 unless you use tape. You are right, that's an odd one on this side of the atlantic anyway. sort of close to whole plate, sort of close to 8x10, but I've about a lifetime of projects as it is. The shipping cost from cyprus is silly. If I can't get ektascan or whatever I will look into a US source.
I searched yesterday for the Agfa film - it is not available unless you find some NOS at some distributors. Ektascan works beautifully and is available from ZZ Medical.Quote:

That said, Has anyone else seen pinholes in the emulsion? There are sometimes what seem like blank spots. Tiny, not visible to naked eye unless maybe in a densely developed area.
The interest in the Agfa is mainly to have a different source just in case. Single sided with anti halation is not a common thing with X-ray films.
Sergei's work is always breath-taking... And the photos are good too.Quote:

I found this:http://spectrumxray.com/sites/defaul...Ektascan-B.pdf
The graph starts awfully high at 400nm, and I'm thinking it might be sensitive to near UV. Can't be sure, as the graph only starts at 400nm. Would it be weird to email Kodak and ask? Is this film still produced by them, or on license by someone else?
I'd say it is uv sensitive, just like most films.
Yes, I have noticed this when I scanned a negative in. Pretty ugly.Quote:

Wow! 203 pages in and finally someone makes it clear, thanks Peter.Quote:

Maybe tomorrow I can put my summary file where it can be seen. It's not perfect, but might help. It's too long to post.
I was hoping pinholes in my Ektascan B/RA was just my batch. I'm still fairly new at all this, I take it pinholes are not a common problem with other X-Ray films or Ilford's or Kodak's usual picture taking films? Or maybe Andrew and I both got bad samples? I have 17 sheets of 8x10 left and about 30 5x7's I cut then I'm out but that could last me a long time. I'd started to think about ordering more.

So here is short summary on Xray choice/shooting/development from me. Just because.
http://sergeirodionov.com/x-ray-film-photography
Foma / Arista are extemely prone to it. Apparently its something about chemistry/water used.Quote:

That is not certain and so I have looked at other options.
Foma list a 10x12cm size in their range for Non-Destructive Testing. I am hoping that would fit a 4x5 holder, although the long axis is 1/4" shorter than 5".
I am seeing If Foma or their re-sellers will deal with a private person & I can get a reasonable amount of film. I have no idea if the stuff is sold in boxes of 100 sheets or a insane amount.
I am well into my second 100 box of Ektascan and have never had a pinhole. I am careful about temperature tolerance through my processing, including final wash. I do not use a hardening fixer.Quote:

Annoyingly I just discovered the German company I was hoping to use doesn't ship to the UK; bah. There's a dearth of x-ray film from the usual US auction suppliers, still searching.

Are users noticing diminished X-Ray supplies?

The stuff is in yellow & purple boxes. The trademark appears to be a red elephant on a white circle.
As the boxes are written in Chinese script I have no idea about the speed of the stuff.
I was gonna have some fun with this, maybe in a pinhole camera.
I mentioned the Non-Destructive Testing X-ray film from Foma, specifically Indux R8 in 10x12cm.
Foma said that the stuff is to order. A minimum order of 63 boxes if they have a master roll in stock, or 213 if they have to coat a roll for you.
I don't think that is going to happen!
I've just ordered a box of 12.7x30.5 Typon DV-G from Bema, for delivery in Berlin. I'll pick it up in a month or so, the next time I get over there.
Conveniently 12.7x30.5cm is 5x12 inches, so I hope to guillotine three 4x5 from each sheet with no wastage. At 38 Euros for potentially 300 sheets, the price is certainly right... I'll be experimenting with Neil on this batch.

An article from three years ago...Quote:

So I suppose when all those hospitals in China go digital, that could spell the end of x-ray film. I would stock up on it while you still can.
I think half the world is still using film x-rays, since the machines and film are dirt-cheap and readily available as those who can afford it go digital. I expect we have another 20 years to buy new film, though I will certainly stock up if I find more deals at $25/box.Quote:

Not so fast, a little Googling reveals more. See also the end of the post.
We are discussing 3 years ago in China. China moves fast. This article below says Digital overtook Film in China in 2006. Furthermore they recycle negatives!
'When he came across an advert from a man seeking negatives, he assumed he had found a rival buyer. Instead, he discovered, Xiao Ma worked in the recycling trade and collected X-rays, negatives and CDs so he could drop them into a pool of acid and sell the resulting silver nitrate to chemists.'
http://www.theguardian.com/world/201...era-film-china
I also thought the Chinese X-Ray boom for Carestream must be old. The first quoted article was not complete, the last essential quote says what will happen, soon. "But Carestream’s film bonanza may be short-lived. Analog x-ray machines have a life of only five to seven years. By the time China’s devices reach the end of their lives, many Chinese clinics will likely be able to afford to retrofit their analog machines with digital scanners or buy digital systems at the cheaper end of the scale. Luckily for Carestream, the company makes those types of devices too."

X-ray film is no more sensitive to the x-ray or UV spectrums than any other film. There are very good explanations of how X-ray film works in this thread.
No, but you can safely assume that the film will work fine with UV and not at all with IR.Quote:

I am aware of the differences between the speed ratings: F being 50% faster than D and 25% faster than E.
Not really. The emulsion is very soft when it's wet but doesn't produce pinholes that I've ever seen. Just handle with due care until it dries. Once dry it's just like any other film. I do use the normal amount of hardener in my rapid fix, however. I know many people use non-hardening fix for both film and paper.Quote:

Speaking with Typon, they told me that they will quit the production of their blue sensitive film this or next year.
But they continue with green sensitive film..

Why would this be?Quote:

Does anyone have personal experience with long term storage of (unexposed) x-ray film in the freezer?
Also, that's a good summation Sergei:
