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

[jb7]

Great news!

What is 'packet loading'?

It's a new design- like a quick load, but for ULF- I posted a pic in the 'show off your camera' thread...

Rushing out the door now, but will report more tomorrow-
Developed a few more...

I think its time for adding pictures..

Please see what's what. A least a few are interested. I see used machines often on E-Bay and elsewhere. The are tabletop models that do up to 14x17.

There was a time when I had to work from time to time in a small clinic. A table top type auto developer was all that they could afford. My main job was to take Chest X-Rays on 14x17 film. As I remember, the smaller machines worked fine. But you do have to know a little about the workings to clear jams, and for periodic cleaning. If anything comes up in my area, I'll pass it along.

Just to make things clear. If its a 7x17, you run it through long wise ( the 7in. in first ) if its a 14x17, it doesn't matter which way you run it through an automatic proc. The idea is so that the maximum amount of roller contact is made, so as to help reduce jams. from...the Seattle guy.

Randy, Just an off the wall question. Has anyone ever tried any night exposures? I have a project I would like to duplicate. I took a photo. class some years ago, and we had to take a night skyline exposure of the city of Seattle. I found the same area, besides an increase in tree growth--it all seems the same. I'll be using 8x10 green sensitive film through a F:4.5 Betax No. 5 lense. Any help would be greatly appreciated. Thanks, From Randy ( the other one )...The Seattle guy...Rde

Not by me, I am mainly a studio guy. I suppose you bracket.

But the real question is reciprocity, I believe.

I've found the Fuji HR-T film very good with reciprocity, with 30 second exposures giving me no problem whatsoever. Should be good for skylines.

From the first batch of 4 negs-

Makeshift darkroom, no scanner. This one a little scratched, but the others seem ok so far-

CSG Kodak, rated 80, or rather 40 with a yellow filter. D76 1+3 10 minutes, 76F.

No scanner, white shirt will have to do for now...

Is this the packet load you spoke of?

[jb7]

Yes it is- and it works...
Needs some finessing now, but all four negs tend to prove the concept.
