A search for orthochromatic film brought up a bunch of "this product no longer available". Is this just completely gone?
 
Most x-ray film is orthochromatic. Works beautifully.
 
tim
i think ilford still makes an ortho film
if you don't mind PAPER instead of film
washi film is a ortho emulsion on paper
you can put in your camera ( 135/120/4x5 )
isn't local though, you have to have it shipped from france ...

...or you can use a Wratten 44 or an 80A filter with pan film to approximate the effect of ortho if that's what you are looking to do.

Didn't Foma used to make one? I don't see it on their website anymore. Emil has been posting images shot on F05 ortho over on LFF, whatever that film is or was. He acts as if its new to him, but it may be an older film. Google doesn't seem to know what it is.
 
Ah, there it is. Seems to be made by Banse & Grohmann but can't find any recent references to it so it is possibly defunct now too.

Well there is this, but you'll have to translate it

I actually stumbled upon this just today:

http://www.ultrafineonline.com/ulorlifi35x2.html
https://www.amazon.com/Ultrafine-Ortho-Litho-Film-Exposure/dp/B00FRUT8PG

I have no idea how good it is though.

its good, but you will have to use a restrainer if you process this in a normal print developer
it can be kind of foggy . jim galli has a post somewhere here on apug or the lf site
where he spells out the developer benzo cocktail he used to hold back some of the fog
to get this film OK for pictorial use.

paper with a yellow filter tends to cut the contrast ( a la gandolfi's portriat work )

or you can embrace the contrast and use it expired so the for you and use it on even lit lighting...

Yes, and also maybe for educational purposes when you want to develop under a safelight.

no reason NOT to develop it under a safelight its blind.

Orthochromatic yes but also high contrast. There are two uses of orthochromatic film first come to mind. Male portraits and outdoors when you want to open up the shadows. In both cases you want normal contrast.

High contrast is easily controlled with proper development.

This is Arista Ortho Litho under studio lights, 8x10 contact print.

ORTHO COPY PLUS can be developed to a normal contrast in ILFORD ID-11 or MICROPHEN and to a high contrast in ILFORD PQ UNIVERSAL and PHENISOL. ORTHO COPY PLUS Film can be developed in dishes under red safelighting.

yes, with regular film this is easy. However when the high contrast is built into the film it is much harder. I have tried on numerous occasions to tame the contrast of microfilm without any real success. A slightly different product but it points out the difficulty.

That is an interesting suggestion. Apparently it is readily available and fairly cheap in quantity.

I am concerned about the high contrast, though. I am interested in making black and white positives by contact printing ordinary negatives onto negative film. The appeal of ortho, of course, is that it can be used under a safelight. But if it is too contrasty the subtle tones will be lost.
 
If you are making positives slides then you need higher contrast just like you have with photographic paper. So in this particular instance you are fine. But this brings up another problem. X-ray film is not intended for projection, that is any increase in magnification. Therefore grain and resolution may be a problem for slides.

But its good for many alternate processes.

This is the best option - if you shoot LF. I've used it quite a bit & like it a lot both as a camera film & for masking purposes in the darkroom.

It's as easy to use as FP4 & can be developed absolutely normally in the usual film developers, or if you develop in PQ Universal it can be taken to the high CI's needed for printing out processes. You can develop it under a 906 safelight.

Frankly, people are wasting their time & money on false economies with X-ray films, when a film this good & adaptable is readily available.

Unfortunately, that film is "currently unavailable". B&H shows an availability in September.

I have two 25 sheet boxes of 4x5 I'll part with. Had them in the freezer since purchased fresh.

Reducing the contrast to the range you want will take a little experimentation on your part. Try developing in HC110 or Rodinal 1+100 with gentle agitation. This should give you a good starting point.

That is your opinion. There are too many photographers doing beautiful work with x-ray film to accept such a statement. At $0.35 to $0.80 per 8x10 sheet it is well worth doing the necessary experimentation to make this film work in the manner desired.
