A few more xray HR-U home rolled 120 film samples (645 format) since it cut me off at 10 attachments from my immediately previous post above this one. All were shot on a pentax 645 with either a 45-85mm pentax zoom lens, or a 80mm Zeiss Jena Biometar 2.8:
Thanks for the detailed write up. The images look great. You must have the patience of a saint.
I greatly envy your lighter x-ray film set up. My RB 67 can be a pain in the ass to lug around all day.
A few shots from the past few weeks. Nothing special just roaming around town with my RB 67 and two grafmatic 23 backs loaded with Fujifilm PX 100NIF. Developed in HC-110.

Xray HR-U / R09
FYI for anyone interested, I got a iso-luminant (same brightness all across) image of the color gamut in HSL space, and took a photo of it with Fuji HR-U green xray film
Then lined up the spectrum image with the photo (adjusted to control black and white card points I included as well) and graphed out the sensitivity of the film by sample points, using the lightness of the B&W HR-U scanned negative
So I believe this is pretty much the spectral curve of HR-U, unless you know something I did wrong. I ordered some RX-N, I will do that one too later.
thanks, that's very useful to know. looking forward to your future tests too!Originally Posted by gavjenks
