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

Thank you, yes that's what I would expect...

Well.. dammit.. i wish i knew it beforehand.. Might've swayed me completely into bringing 8x10.. but then even 4x5 ended up pushing limits of weight allowance ;( Of course it makes a good fun when you go through whole weight discussion and then do the usual "ok, then i shall take my camera out, since its not included in weight limits, as per your regulations"... Used to be more fun with Technika than with Chamonix but still.. eyes gouged, veins popping...

Lol

From a old X-Ray Tech. Back in the day, we used cardborad holders. It gave you greate views, but at a cost of increased X-ray exposure. The film hasn't changed much, but when "green or Blue " emiting screens came along. The exposure came down, and the picture quolity stayed the same. So X-ray will effect the film, it just determined by how much. Seattle man...Rde

To cut in the dark, try this. If you use 8x10 film, use a paper cutter set at 5 inches. Then cut at 4 inches. I would make it so you could feel the inch mark settings in the dark ( you might make a cardboard templet ). For other sizes, you might try making up a device that will pre-measure the un-cut film at a desired size. Just somethng to try. Seattle man..Rde

I have cut down 7X17 into 14-2x3 pieces for processing experiments. I bought the 7X17 for a 7X11 camera and will have 5x7 left over. I seem to prefer the more rectangular formats.

I use Rde's methods.

Now I am waiting on 11x14 X-Ray Woo-Hoo!

Aha.. Thanks for chiming in, Randy. Like i said then - should have brought couple of test sheets.. That would clear questions up.

Woo-Hoo. UPS just delivered Kodak CSG 11x14 $77.75, 100 sheets 3 days, order to door. They are quick.

Now I need to find my scotch tape and tape a couple sheets in my 2 converted Process camera holders.

1 to 1 head shots, coming up!

Is that Kodak CSG single sided, Randy?

I am trying to work out processing in the Beseler drum and base - but scratches are killing me! I can still strip the back, but it is yet another pain... Maybe I'll go back to trays.

Here is an overexposed Fuji HRT shot, processed in the Drum - AFTER I cloned some of the scratches...

And another:

doubled sided, I don't strip and I will be doing 11X14 gently in trays.

I am setting up 8X10 tanks and hangers for normal film and X-ray, as soon as the tanks get here.

I only last week started using 4X5 tank and hanger, what a pleasure.

I have drums, but think they may be a bad choice. I have not tried them.

Did you know Garry Winogrand was known to just dunk 35mm into buckets, loose, and let the scratches happen...?
