eBay item number:

I know you said you wanted single sided, but here is some double sided. A quick rub down with bleach and you have one sided.
price is right

I've always understood that panchromatic film was more expensive because its chemistry is more complex, requiring special dyes to extend sensitivity into the red wavelengths. I think you're right about marketing factors. When you consider for example how much xray film is used compared to panchromatic film for b&w negatives, the large medical market probably keeps prices competitive. As use of film declines for xray imaging in favour of digital, I wonder if xray film will get dearer?

In trying to locate xray film my wife rang around several hospitals and mammography (single sided xray film) clinics, unfortunately all had gone digital, the reserves apparently had the silver reclaimed from them. I have seen a steep decline in availability on ebay as well. So I have stocked up on 8x10 10x12 and 11x14 before it becomes history.

Have just tried out some 10x12 green x--ray film, seems to be a little more robust than the half speed blue I have been using. Both are rated at iso 100. A little less grainy as well.

Well its great to see such a communal site, though I have tried I have not been able to initiate any kind of dialogue. Actually one I tried to help ignored me completely. Good luck all!

It seems green is the more popular option, ive enlarged a Kodak XRay on some fomatone 111 which came out pretty well.

Re: X Ray Film Some images and scan with comments

I recently put some x-ray film images up on the Things of some Gumtrees,it occured to me that some examples coupled with exposure pitfall would assist any who are considering x-ray film as worth pursuing.
My camera is a restored Kodak2D
Lens G-Claron 270mmF9
yellow filter used sometimes
Sixth x-ray shot after completing 2D(Ithought) 11-08-2013
Fuji HRT 240x180
exposure 11.7sec F45
Developer Rodinal 1:100 5min30sec

resulting print was lacking in contrast
the massive black film holders are cut pieces of thick paper to hold the 240 x 180 film
You should notice the dark area right of centre this haunted me for over 12 months
This is a scan of a print.
Still life taken in bathroom under subdued light through window
exposure f11 1m13sec
Dev Rodinal 1:100 5:12s
Again lacks contrast in printing

Spa Area convenient test shoot area under subdued light
our R&R area
Exposure 1m49s@f45
Dev Rodinal 1:100 5min 31s
An Improvement

All for now I have almost 70 early x-ray images which may shed some light on taking and printing x-ray images
I hope this may generate some interest in the fasinating area of Large format photography
if not we will go the way of other LF site such as F32.net which I watch shrivel up and die
so post some shots what worked and what did not!

it's hard to tell from a monitor screen but those three positives in your last post look like they've come from "full information" negatives; detail in the thin bits, detail in the thick bits, and everything in between. Your exposure + developing protocol is working. Ok, the extra edge density is a bit mysterious: light leak, agitation artefact, camera body flare, edge fog on film .... ?

Maybe the next challenge is getting those good negative densities to lay down good tones on photographic paper. That's not always easy but I reckon it's easier than taming x-ray film.

Thanks Maris the deceptive bit is those shots were taken using a BTZS Profile which originally was for APX100 and a series of tests and short cuts at Steve Nicholls darkroom he modified the film curve which seemed to be spot on.
Soon it showed promise but had shortcomings, You're summing up "light leak, agitation artifact, camera body flare, edge fog on film .... ?
it was all of those at separate times,When you have not done any 8x10 at all your head gets in the way,i thought for sure it was light-leak but centered mainly around the lens boards made by me 6mm MDF. I used bookbinding tape and put 500 gm of extra weight yet still it persisted.
This film is Fuji HRT double sided
Studio shot used some flash-heads
1 sec f8 My Grand kids
scan of print foma paper
No flare ( darkened area)
first hint I was doing something wrong when removing and replacing the dark-slide.
I know that now not then

Medical Centre Nourlunga Centre
Bright red structure 2Pm afternoon
180x240 neg Fuji HRT
Exposure 1 sec F45
used white curtain blockout material as hood and hung it over the film area

later that day we went to Hindmarsh falls just before a lightning storm and heavy rain this was attempt 4 or 5
The air was crackling and my wife was staying in the patrol yelling out hurry up ,I had just packed up when Boom came the thunder and lightning!
The fallen tree is no longer there,I don't know what happened to it possibly set on fire LOL.
Hindmarsh Falls near Victor Harbour
180x240 Fuji HRT
Exposure 1 sec F45
270mm G-Claron lens

The prints from these were all tests for a trip to Kangaroo Island Which was a disaster, I told Steve I had put some stuff up and one of his comments with X-ray film was 'You never know until the next exposed neg.'
All of these examples are scans of prints using View-scan on a HP Scan-jet 7400C
