Moonrise Over Newly Planted Vineyard
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.
Speed Graphic with Optar 135 at f8
80min exposure
Agfa HDR mammography film
Tray developed by inspection in Ilford MG 1+100 at 22C for 20min (semi-stand).
Scan from negative, finished in PS.

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.

Re: Use of X-ray film: technical discussion with example images
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.

Re: Use of X-ray film: technical discussion with example images
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.
Re: Use of X-ray film: technical discussion with example images
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.
Re: Use of X-ray film: technical discussion with example images
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.
Re: Use of X-ray film: technical discussion with example images
I can't read Chinese although I work with a team in China who could probably translate it.
In the mean time I cheated and used my phone to translate from the picture.
The first lines basically says something about medical use X-ray standard dental film and the bottom line is the name of the manufacturer which is...
Tianjin Kang Chinese Health Materials Ltd
Good luck
