    Andrew, is there is a way to mess it up trust me I'll find it.

    Yep - I still haven't run into any significant reciprocity with the HR-T film, even for 1-minute long exposures. One of these days I gotta do some tests for really long exposures, like 10+ minutes.

    Yeah, I had read that it needed extra time (almost as much as other B&W films), but I 've not treated it the same as I would treat say Tri-X. Would love to see some longer exposures like you mentioned.

    All films suffer from reciprocity effects, including x-ray. I have my own data that I apply to the green latitude stuff.

    Great image. Shades of Stieglitz...

    Finally shot some Kodak CSG 8x10. A pleasure not to cut it to size. 1 sec f22 ISO 80. LED lights. Rodinal 1/100 5 min Ziploc. Did not force the neg in long way. I like the Ziplok method, would be great for 5X7 and students. No mess, very clean and dry. I used high quality slider bags. Cheap at Costco. Self portrait with Autoknips II, a great invention. Hard to visualize that neck shadow...

    Re: X-ray Film example and comparison.

    Posted to the other X-Ray thread, but I think I need to be here. Kodak CSG 8X10 1/100 RO9 5 min Ziploc LED lights made 2 images, one stop apart. This is 1 sec f22. Self portrait with Autoknips II timer PS curves, no spotting. Getting a Costco print in 2 hours to see how it looks at 16X20.

    Like it. Can I see a wee bit of mottling?

    Re: X-ray Film example and comparison.

    The background was mottled on purpose with the LED lights. I could see it with my eye. I see scratches. The neck shadow was hard to predict.

    I am changing backgrounds now.

    Shoot later tonight.

    Hard for me to really see it on a monitor. The Costco print should be interesting.

    Better get there now.

    Very cool, Randy. Looks like you're getting some scratches though. Changhwan finally got his Agfa x-ray film and did some ISO tests yesterday in D-76. I had to leave the school early, but hope to see his results on Monday. Everyone was in awe of his camera, saying things like: "Is that a camera?!"
