I have Fuji FP series that was frozen, by the Pro that gave it to me. It has been OK. But they don't recommend it. The frozen Polaroid from the same donor is ruined garbage.

The big difference I see is packaging. Fuji seals in metallic foil and Polaroid a sealed paper.

But this thread is about X-Ray and Fujiroid is an entirely different thing.

I'm still in testing mode with the Agfa HDR film.
But I can only take all the mind-numbing curve-plotting up to a point.
Real life pictures is all that matters, so I just couldn't resist trying out a night exposure.

I think that's a first like that.

Well done!

Posted this in the pinhole thread but since its the first x-ray image I'm even remotely happy with I'll post it here too. If it turns out half as printable as it looks here, it'll be my first decent print from x-ray film but I don't hold my breath.

Fuji 8x10 HR-T X-ray film, f250 @ 8 minutes in Ansco Universal 8x10, with #11 green and #8 yellow filter (why? why not) Rodinal 1:150 7 minutes in tray with only one or three glaring scratches (I put a blank fixed sheet under it and got a lot fewer scratches). Agitated 20 seconds then 1x/minute. Unadulterated straight scan, which I apparently didn't line up to the scanner's liking so one long edge is missing and I'm too lazy to do it over.

Thanks Randy!

And another one:

Yesterday was Worldwide Pinhole Photography Day (WPPD).
This was my contribution.

The first of my X-ray film has arrived... As you can see it was the box of dental films. I only ordered it on the 19th April & it came from China a week later!
Can anyone read the script on the box? Just in case there is any information I ought to know...
I don't know who the maker is for certain either.

"Only works on elephants." :p

If it were elephant size sheets the box would provide a thousand sheets of 4x5.
Seriously: Does anyone know Cantonese, or whatever the script is?
If the packet colours do not follow international standards to denote the speed band I have to look at the packaging.

I sacrificed one piece. The packet (& film) are impressed with a pimple mark in one corner, which shows which side should face the tube.
You wouldn't know which side the emulsion was from the surface appearance.

Is dental X-ray film normally double-sided? That is what it looks like. The pocket had no lead foil inside. The film was enclosed in a fold of black paper.
The emulsion/s, if there are coatings either side are thin enough to see through. You can see light through the film.
