wow, how did you developed this in a rotary tube? didn't you get scratches and uneven developmpent on the side facing the tube?? Or is there something I'm missing about Kodak G X-Ray?

First two sheets of Ektascan developed. Both exposed at EI 100, and companion images on FP4+ at same exposure for comparison.
1st sheet in tray with HC110 1+63 for 6 minutes almost constant agitation+ 2 minutes standing in water. Shadows are under-exposed, although FP4 is not. Contrast a little strong even for salt prints.
2nd sheet #12 filter to separate clouds EI 100 plus allowance for filter. in tray with HC110 , 1+100 for 12 minutes, limited agitation (5 seconds each 30 seconds), + 2 minutes standing in water. Contrast better, but of course shadows still under-exposed. sky and clouds look good.
Not unreasonable for 1st tests of this film. I'll get where I want to be soon.
I will probably move to D-23 + water bath, and Pyrocat HD for next tests in my search for the EI /developer combination which best suits my work.
An aside - the FP4+ negatives look very good with a nice long scale.
Some will ask to see images, but I stopped putting images anywhere on the web because of theft and use for profit. That is why I no longer have a web site or blog.

I'm not paying for this article? Will someone?

I been working with X ray in rotary tubes since day i started using Xray about year and half ago. Only two times i had actual issues - one time when i was stupid to develop it in Jobo tank for paper and then back emulsion was not developed. Other time when i was idiotic to drag film out of tube be the edge and scratched other sheet with it.
if you use film tubes (like unicolor) or other contraptions (like core inserts) you actually got liquid go between sheet and sides. I never strip my film other side , b/c i hate doing it :) It just takes some practice and being careful, and then things working just fine. Sure, you might get scratch here and there on edges, but who cares (few mm out of 8x10 real estate won't hurt you). Its hell of the lot easier to develop for hour in rotary, than doing so next to the tank in dark room, and doing it "by inspection". I don't have dipping tanks though, they might be not bad solution either.

Cool roots!
I've just confirmed the X-Ray is completely orthochromatic! This is exciting to discover, that it's almost fully so, not just a tiny bit... I'm going to try the normal green stuff to see how it reacts to the amber darkroom light.
I just ordered more of the ektascan, and that's when I realized it IS the green I ordered as it's the cheapest, so it's considered 400 yet I've had to shoot it at EI80 to get a good neg... Hmmm.
Stone, my experience with CSR green latitude is that it is only slightly orthochromatic, or better described as a week panchromatic. My first attempt at processing with a red bulb resulted in slight fogging. I had to move my safelight farther away.
With Fuji Green, I tried using first my normal orange/brown (OC?) light and it was total fog. Then I tried a red bulb I'd gotten from a photo supplier as a safelight, and that wasn't much better. Finally I just caved, and bought a real x-ray safelight on Ebay. I haven't tried the LED thing. I intend to try LEDs, and think you should try them first. . .The real safelight is very very dark, so I don't even bother to use it.
It's confirmed when I looked at the dry neg this morning, absolutely no fog from standard amber safelight, so the ektascan can be opened in the darkroom no problem! Awesome now I can cut some 4x5 and actually see what the heck I am doing! So glad to finally have access to a darkroom!
I use Kodak T-MAT G/RA Xray film and I load and develop them with a "normal" red bulb safelight at about 1 meter, it's a bit dim but no fog at all.
