Re: X-ray Film example and comparison.
Hey all, I'm curious if anyone has travelled with X-Ray Film.
I have a box of Ektascan that I'd like to take with me when I move to S. Korea and then to a few other places when we do some travel.
Any chance I get away having my box hand-checked? I'm assuming that x-ray exposure is a big no-no...

Re: X-ray Film example and comparison.
Xray film isn't any more sensitive to X-rays than standard photographic film. The image on an xray film when used in medical imaging is formed by visible light from the fluorescent xray screen, not (or hardly at all) from direct xray exposure. So only the same issues apply when travelling with xray film as normal film.

Re: X-ray Film example and comparison.
That's great to know.
Cheers, Dave!

Re: Images shot on X-ray film
I'm really liking what x-ray film does for portraits. I'm running through a shoot,
so there will be more of these on my flickr LF page, as I get them done.

After reading a large chunk of this thread, I'm still unsure on which film I want to buy. I never bothered with xray film in 4x5, since Arista Edu 100 is so cheap, but recently decided to play with 5x7, and my film options are far more limited and more expensive. Xray seems to be the budget hero. My plan is to buy 8x10 stock, cut it down, notch the sheets, and then strip the emulsion from the 'back' side. I'd probably just contact print the negs, since I only have a 4x5 enlarger.
What's a reliable go-to film/developer combination to start with? I was planning to dev with rodinal 1:100 in a print drum (hence stripping the back side off, since usually my negs stick to the inside of the drum). I was planning to buy either Fuji HR-T green, or Carestream's private label Kodak green product.
Consider Ektascan if you are using 8x10, it has numerous advantages over Green but It's pricier.
-
Re: Images shot on X-ray film
Since I use both films, the advantages I can think of is: Ektascan is single-sided, so easily processed in drums or tubes; is sharper; less chance of scratching. Tonally, I feel Green lat is nicer, though.
-
Re: Images shot on X-ray film
Awesome, thanks for the input, all! I picked up a box of fresh 8x10 Fuji green stock on eBay for peanuts, and it should arrive in a few days. My plan is to cut a few sheets down to 5x7, burn them in my Graflex, and see how it contact prints.
Eventually I'll get my hands on some single-sided stock like Ektascan, but I'm not in a huge rush. I'd rather keep an eye out for some at a price I like than buy/ship just one box from an xray supplier.

Re: Images shot on X-ray film
Long time no shutter. Beard goes tomorrow as its back to work. This is the first sheet of LF film in a long time-felt good even if I over exposed about 3 stops and scratched the daylights out of the neg. I have around 800 sheets of the stuff-might as well start ripping through it! Eagerly waiting to get into the new home and building out the darkroom.
Slight crop and tint- diagonal line artifacts are from the 4990 when the negs get too dark.

Re: Images shot on X-ray film
Developed some of my first test shots on XRay film today - CSX Green. Based on combing through this thread I shot most at 80 and some at 50. For development I used some popular developers and times I found here also. They were: (at 80) Rodinal 1:100 7:30; Rodinal 1:50 7:00; PMK 6:00 and (at 50) Rodinal 1:100 4:30. I started with a Jobo 3005 on a motor base. I only used 1 tube and 400ml of developer after a prewash. The first one (Rodinal 1:100 7:30) was fairly dense but the back side was under chemicaled in areas. For the second (Rodinal 1:50 7:00) I aligned the joint of the film to the outside edge of the tube and reversed the rotation half way through each step. This worked well, but was really dense. The third (PMK 6:00) wasn't too dense but again suffered from back side surfeit. In desperation I turned to an old enclosed rocking tray and tried Rodinal 1:100 at 7:00. This worked fine but was really really dense (and a pain to rock for that long). This tray used to be motorized but one of the gears gave up. Anyone have one they aren't using? For one last try this evening I used a negative exposed at 50 back in the Jobo with Rodinal 1:100 at 4:30 but increased the chemistry to 800ml to try to get more action on the back side. Again I reversed rotation half way through - yeah, I know Jobo says this isn't necessary but the first test had favored one edge of the back. This was evenly developed but again really dense. I'll contact them tomorrow and see how they will print.

Re: X-ray Film example and comparison.
I am from Romania, here (as I suppose all over Europe) the easily available sizes are only metric:
13x18, 18x24cm and so on.
My question is:
it will go in 18x24 holder without trimming ?
I know that 8x10 xray doesn't need trimming.
To buy an 18x24 holder is not easy or cheap. If the film need additional trimming I'll better search more for 8x10 film.
-
Re: X-ray Film example and comparison.
I managed to buy 3 holders from ebay Germany. After I have the holders and the film I'll post here if the film goes in the holder without trimming.

It seems that everybody has deserted the site, I am also a beginner, all I can say is that if you can avoid trimming, then do so. Xray film is very easily scratched.

Re: X-ray Film example and comparison.
So I created this YouTube video to show people how to remove the emulsion on double-sided x-ray film. I posted a new thread about it, but wanted to link here so that people could see it.

Re: X-ray Film example and comparison.
OK, I tested Carestream 13x18 Green film and is going perfect in the 13x18 holder.
I'll write a little more because I am very happy.
Last year I bought (impulse bidding) of ebay a strange 5x7 camera, Ilko (the final price about 100 EUR). It is an awful camera, bad shape, with some no marking holders. I put it aside and never touch it for a year and never bought film for it.
Attachment 128066
After a long photo pause I started to play with Ilko, it is still bad but usable. Today I had the bright idea to measure the holders.
To my surprise the holders are in fact 13x18cm and not 5x7 (as described on ebay). I run to the film supplier and bought a pak of green Xray film for about 10 EUR.
I exposed two sheets and developed in an exhausted, one year old Foma LQN. To my surprise the negatives look really, really good.
Attachment 128071 This is a (partial) scan on Epson 3200.
I tried to do a contact print but the timer give up and I had to expose by felling and the print is not so good.
Attachment 128072Attachment 128073 My darkroom (bathroom) is really, really low tech, the lamps are attached to the aquarium stand.
The xray film is cheaper than paper and for me easier to buy, just walk in the dealer office, say hello and 5 minutes later walk out with the film.

You should watch the video as most of your questions are answered simply by watching it.
I find it easy, and if you have no trouble then there's no reason to remove one side, if you are like me, then your development times and densities are too heavy with both sides, and you get scratches on one side with using a rotary tank which is what I have trouble with, so I remove the scratch side and this gives me the right density for printing and allows me to have a clean image with no scratches

Re: Images shot on X-ray film
What's wrong with the contrast in this pic? Looks great to me. But if you have a subject that needs less contrast, try using a stop less exposure. Also Sepia Toning was a traditional way of reducing contrast. On a wet print, of course. Sepia control on computer prints doesn't work, in my experience.

Which wrong X-ray thread? This one? http://www.largeformatphotography.in...ilm+comparison That was the first thread on X-ray and I still think this one should be merged with it. Why have two threads?

"In contrast" (pun) this is the same shot but using HP5+@250 in DD-X (posting for example purposes I know it's not x-ray film) to show you how the contrast is much reduced.

Re: X-ray Film example and comparison.
How much are you diluting DDX? Have you tried exposing more and developing less? Are you printing the negative or just scanning them?

I have a bathroom with a custom made aquarium stand (3 aquariums). It is in the bathroom because I continuously change the water by droplet (another low tech setup), and now it also act from time to time as a darkroom, only for tray development and contacts.

Hence the need for one thread. Technical and images combined, saves the trouble of going between two threads. Even if you have a thread solely for images, someone is going to ask something technical about it.

Re: Images shot on X-ray film
Thinking on this problem, I think you can reduce contrast with various strengths of yellow filters. I like the shot done on ortho (x-ray) film better than the one on pan film (hp 5). It would be interesting to re-shoot that one on two sheets of film. One like you did the first one, and one with a 2X yellow filter. That would tell us for sure if a yellow filter reduces contrast. There is nothing wrong with the one you already shot, but by shooting them one right after the other it eliminates some of the variables. I'm sure you know that "2X" means requires twice the exposure. I put that in there for those who might be reading this and don't know what it means.

I've not heard about that filter, I have a standard yellow and a #12 yellow. That's all I've got.

Re: Images shot on X-ray film
I have experience with yellow and green filters with xray film. I have posted info with examples on the other xray thread, as well as reciprocity data. Ignoring reciprocity can result in a very contrasty negative... in my experience, especially for silver printing and scanning.

That certainly is a good way! Or an even better way is in-camera pre-exposure.
