Re: Use of X-ray film: technical discussion with example images
I have sad news: Carestream Ektascan B/RA has been discontinued. Does anyone know of any other single-emulsion films available? Or does anyone have any leftover stock they're not using? I'd come to rely on its orthochromacy for a particular project I'm doing.

Was this from the manufacturer? A supplier? Or somewhere else?

Re: Use of X-ray film: technical discussion with example images
Curious where everyone's getting their x-ray film? Also, besides the difference between the blue and green and single- and double-emulsion versions, there seems to be an astounding variety of special application films (mammography, etc.). Apologies if this has been covered already, but with 500+ posts in this thread I haven't been able to find a basic explanation of what to look for in these. Can anyone briefly outline the most fundamental differences?

Re: Use of X-ray film: technical discussion with example images
ZZ told me the same and refunded me $320 from a case order this week
Perhaps I got the last 2 boxes last month, when I placed the case order and paid for 5 boxes
They said at that time they had some coming...guess not...or a machiavellian plot is afoot...
BUT 6 years ago I was told by ZZ 14X17" Ektascan was 86, but I and they persevered and found me a case after a long while
Sometimes there is some somewhere, but right now nobody is searching too hard, as few are working or if they are, they are maximizing their profits, just as I would...
I suggest you buy 2X-side now, before it goes, it also works fine

Re: Use of X-ray film: technical discussion with example images
I buy only from ZZ and usually only Carestream which is made by Kodak and is T grain
Double sided seems to be all there is now
8X10 and 11X14 will fit normal photo holders, the rest is a crapshoot
But I often cut it down to smaller sizes and I see right now none is FS on ZZ from this list https://www.zzmedical.com/analog-x-r...-ray-film.html
IF and I am not buying anymore this looks like a great deal https://www.zzmedical.com/analog-x-r...-ray-film.html
I have been warning for 2 years that X-Ray film is dead... soon
AND MOST OF US HAVE READ THE WHOLE THREAD

Re: Use of X-ray film: technical discussion with example images
I agree,and I also bought only from ZZ It's too bad the Carestream single sided is no more,but I have my lifetime supply. My wife has frequently said I am going to die with film in the freezer. I hope so, and at 91 it's very possible. So goes life.
Those who missed out on the final run will have to learn to be extremely careful so they can use the double sided stuff. I am in the same boat with 5x12, but it doesn't worry me. When I began this voyage through a life in photography, all the film was very delicate and had to be handled with great care. It only takes practice,a lot of practice, so hang in and don't give up.
-
Re: Use of X-ray film: technical discussion with example images
The best way to use the double sided stuff, in my experience, is in a vertical tank to avoid scratches. I built one out of acrylic for 11x14.
-
Re: Use of X-ray film: technical discussion with example images
I agree with Jim
2X X-Ray works fine, it does scratch if not loaded carefully. I learned how to NOT scratch even with my clumsy fingers
I recommended the above 2x, buy the cheaper Green as it's way cheaper. Always buy the cheaper, blue of green means almost nothing for our uses.
I also recommend the same thing in 14X17" as it does fit 14X17" plastic Medical DDS https://www.zzmedical.com/analog-x-r...-ray-film.html
Which is almost exactly the same price per sq inch
I have cut 2X down to fit Hasselblad sheet film holders, and was amazed how sharp the tiny images were.
-
Re: Use of X-ray film: technical discussion with example images
Someone was looking for some Ektascan B/RA to finish a project. I have a little (under 20 sheets) if that's helpful let me know, it is 8x10 and several years at room temp, it worked fine the last I used it but darkroom work is on back burner right now. I'd like to recover cost and shipping.
I've also cut it down for 5x7 and that leaves you with a 1" piece that makes super sharp images in 35mm cameras loaded in the red lighted dim/darkroom.
-
Re: Use of X-ray film: technical discussion with example images
the link above is to 14x17 at 86 cents a sheet. Wow. Might have to build a 14x17 so I can afford to shoot film...hahaha...not funny. seriously tempting. I think I will stick to 8x10 for now, and learn to do good work on 2 sided in film hangers in skinny tanks first.
-
Re: Use of X-ray film: technical discussion with example images
Thanks for the reminder. Bought 200 sheets of 14x17 film because...well I have a 14x17 holder here now.
Nothing else, but that's a good start! :)

Green is orthochromatic, blue is just blue-sensitive. That should make a huge difference in tonality. Anyway, just ordered some green Fujifilm from ZZ. Worst case scenario will have lots of practice film.

Re: Use of X-ray film: technical discussion with example images
Look for Agfa Mamoray HDR-C Plus...its single sided. Looks like it comes in 24x30 cm.

When it comes to learning ultra-large format, having cheap practice film is necessarily part of the best case scenario!

Do you get Fujifilm in 8x10" or 18x24cm?
Thx

8x10. Wouldn't have much use for 18x24. Otherwise would have gone for the single sided mammography film.

Re: Use of X-ray film: technical discussion with example images
Here in Europe we only get the 18x24cm version, that's why I was asking! I'd love to get it in 8x10"...

It really does seem to depend. I've looked at the spectral sensitivity charts for Ektascan B/RA and UM-MA (a supposedly green-sensitive mammography film), and both are almost identical across the graph, despite differences in the way they are advertised. I would assume that HR-U and others are very similar. I'm currently awaiting a test box of some expired UM-MA, which should be in the mail right now. If it works out, I'll let everyone here know.
Fujifilm UM-MA is, by case, slightly cheaper than Ektascan B/RA. It has roughly the same spectral sensitivity, and possesses single-sided emulsion The only major disadvantage is that it comes in 18x24cm or 24x30cm sheets. This means that one has to cut it down rather wastefully, if they are turning it into 4x5 sheets. At 427$ for a case of 24x30cm sheets, it will work out to being about .30 CAD per sheet before shipping, which beats Ektascan B/RA by 2 cents CAD per cut-down 4x5 sheet.

Agfa Mamoray, as I discovered, does have a different spectral sensitivity profile. You can see it here: https://medimg.agfa.com/dach/wp-cont...R-C_Plus-3.pdf. For normal photographic purposes, it should not be very different from any of the others, excepting that it is much less sensitive to UV light. This may prove to be an advantage for many of you. In my case, this is actually a problem.

Re: Use of X-ray film: technical discussion with example images
What is your supplier?
Does UM-MA have anti-halation layer?

If I recall correctly from the datasheet I found, it does. ZZ Medical sells it, only by the case.
-
Re: Use of X-ray film: technical discussion with example images
I doubt it does, I read the Data sheet, no mention
Ektascan was made for photographing CRT screens, anti-halation would be good for that, not sure if Mammography screens would need or want it
https://www.breastcancer.org/symptom...mmograms/types
Nonetheless, the ZZ price is good, but the wait is long
I now worry any business may disappear shortly, every $$$ counts now

I'm happy to say that you're incorrect. It's on the datasheet.
Attachment 203727
I also found a paper where B/RA and UM-MA are directly compared (https://core.ac.uk/download/pdf/12529443.pdf), which does buttress my case that they are probably roughly analogous. I encourage anyone to review the datasheets of both. Their spectral sensitivity profiles are nearly identical. By most metrics they are analogous, save for the formats they come in.

Re: Use of X-ray film: technical discussion with example images
As for the wait at ZZ, I called them and specifically asked about this film. They told me that the wait time posted on their site was inaccurately long.

Re: Use of X-ray film: technical discussion with example images
Okay, so I have my hands on some UM-MA. Has anyone here worked with this film before? I'm going to start testing both dev and exposure, then will report back. To begin, I will develop it as I did EB/RA. Does anyone have any thoughts as to why that might be a bad idea? These films seem very, very, very roughly analogous.

Something called M Plus - Half Blue. Shot at 100, dev HC-110 h for 6 minutes. 10 stop ND filter. Used reciprocity times for Delta 100 as an experiment, which has failed at night but worked great during the day for this test.

A local doctor was upgrading to digital and couldn't find anyone to dispose of the old stuff, so I loaded it all into my car. Dropped the chemicals off at the hazmat facility, kept the film. 150 sheets 10"x12", expired 2014. Cut down to 4x5 with a Dahle rolling trimmer.

Re: Use of X-ray film: technical discussion with example images
With 559 pages in question I hope that you forgive me asking, but has anyone recommodations for Fuji UM-MA or Agfa HDR-C in HC110 or Rodinal?
I've noticed today with horror that the Fuji AD-M, which came great in HC110, is discontinued :-(. So I have to look for alternatives ...
-
Re: Use of X-ray film: technical discussion with example images
All analogue, and not Laser X-ray film is easily processed in any 'normal' film developer, stop and fix.
It's real film

6-7 minutes in Rodinal 1:100 at 68F is almost always what I recommend starting with for any x-ray film.

Re: Use of X-ray film: technical discussion with example images
ZZ medical says that Ektascan is gone. They recommend trying: https://www.zzmedical.com/analog-x-r...tomtabs_tabs_1
500 sheets of 18x24 cm =7x9.4" is $285 plus shipping.
500 sheets of 24x30 = 10x12" $427 plus shipping.

Although x-ray film seem to quite differ in ISO as far as I have read here ...
BTW: Kodak Min R 2000 Plus seems to work very well either: https://www.flickr.com/photos/macieklesniak/16193630057

Re: Use of X-ray film: technical discussion with example images
They may differ in ISO (EI) but this doesn't mean that formula is not a good starting place for development. The common suggestion is to "test" because it is fairly cheap to do so.
Recently got a couple boxes of my preferred slow, green-sensitive film in 14x17...now just have to find/build a way to expose it :).

If the HRU works out well for me, I will load up on it. Is anybody using the blue Fuji, is it different in use from the green as in worth having both?
I know the MINR is one sided so I picked up 300 sheets at a good price. I do have 18x24cm Film Holders and that will make nice contact prints. Also I can quarter these into four 9x12cm sheets :)
I do have some holders loaded up. Just waiting for a strong subject to pop up when I have time.
