Hello all! So I'm thinking about switching over to X-ray film for use with the 4x5 and 5x7 cameras.

I keep hearing about it. So to that end:

Any direction with regard to the purchase of said film.

Direction with regard to suitable developers: (I normally use D-76 for dev w/ HP5 400 -current sheet film being used)

Is it known if it produces suitable negatives for Pt/Pd printing?

Any other tidbits of info would be helpful and appreciated!

V/r,
Dodge

I currently use the Kodak RA (I think that is what its called) it is single sided emulsion, I rate it at 100 and process it in with d76 1:1 for around 6 minutes for normal contrast negatives, its a great film, I shoot it in 8x10, 100 sheets is around 90 dollars, you can get the double sided film much cheaper but you have to be careful when processing because its very easy to scratch, I have only shot the green sensitive film and have had really good luck with it. as far as reciprocity, anything over 1 sec just add a stop, so far I have shot it up to one hour and it was dead on. here are a couple of examples

I guess no one else is going to say it: there's a whole thread for this topic-----all the information you will ever need, hundreds of pages with all sorts of good stuff.

I am going to say something different,the thread is 400 plus pages long and very difficult to use.

So start at the first page and read until you are tired of it. That's still a better idea than starting through the same stuff all over and thinking that everyone will happily repeat themselves for a lazy person. What I still do came from the first five pages of that solid-gold thread.

Notice how no one is responding to this thread.....I'm pretty sure everyone is on the same page here.

And, if you have any idea of something specific you're looking for--say, a particular film or developer use--you can search the original thread.

With one exception, short strings of text like "d23" yield no results.

I'm a web developer and no stranger to computers & software, but I've yet to figure out how to search a specific thread. Plus the search function is limited to OR Boolean searches, further limiting its utility.

Original poster: the single-emulsion film mentioned earlier is available here (https://www.zzmedical.com/8x10-in-carestream-kodak-ektascan-b-ra-single-emulsion-video-film.html). Many on the forum rate it at EI80. Its limited spectral sensitivity causes it, like all ortho film, to lose speed when there is less blue light so outdoor shooting before 10AM or after 4PM will drop the EI considerably, as will working under tungsten lights. There's a lot more you need to know about it (e.g., don't work under an amber light, buy one of these instead (https://www.superbrightleds.com/moreinfo/led-globe/2-watt-g11-globe-bulb-360-degree/440/1477/)), and until we get a FAQ sticky going, your best bet is the x-ray film thread.

Best of luck and welcome to the wonderful world of x-ray film.

The best way to search the forum is by putting this into google: site:largeformatphotography.info xray film in d-23

True; you can use Google search, and then you can use Boolean operators (https://support.google.com/websearch/answer/2466433?hl=en).

I'm not a fan of the merge. It satisfied a compulsive need for neatness that some suffer from but few people are going to read it now that its so long which makes it rather useless. I read it when it was 2 threads and it took days and days. When I want to re-read it...I won't. So not everyone is on the same page, but majority rules.
