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

I have been using a Unidrum for prints to develop my 5 X7 negs. So far no scratches on the negs. The unidrum for prints doesn't have internal ribs for the neg. to rub against.
Got this information from You Tube and then tryed it myself and it works.

If you have tanks use them and if you have drums scratch and strip! Good luck!

Has it been mentioned anywhere WHY x-ray film scratches so easily? If so I don't recall the reason after reading 50 pages about xray film this week.

2 sides of emulsion, nowhere to hide

Just a thought, try checking out Wilhelm Rontgen's picture of his wife's hand. He used X-Ray and film. It looked bad,
but it worked. Seattle man....Rde

The emulsion is about 0.0005 inch thick. It's on both sides of a flexable transparent base, so it can be easily scratched. I hope this helps

I use drum. Rarely scratching. Out of couple hundreds of shot film sheets (so far) i stripped like 4.. ;)
However - depends on drums. If i were to use jobo ones i'd be doomed (tried).

Exposure with the Fuji AD-M seems like it needs to be very precise. I'm developing in Pyrocat-HD, which is very forgiving and gives me nice negs with just about anything I throw in it.

I have a feeling the Kodak is going to be similar, because the customers expect x-ray products to be fairly similar across manufacturers. Gotta test it though. Probably bought too much of this without testing some samples first. It's mostly metric sizes, which is a pain. I got it so I could develop it in a Jobo Expert drum, but I seem to create three problems for every one I solve. :rolleyes:

Are you putting this Mammo film into your holder the right way? The emulsions on Min-R are not symmetrical. The top emulsion has "regular" sensitivity and response s curve, the bottom emulsion is very very slow, practically no response until you get up to the top of the front emulsion s response curve. At least that is how I interpret the film data. The bottom also has an anti halation layer, so you probably could not expose backward.... In any case, how does the exposure look on the back side? I would guess it's mainly clear on the negative?

I haven't gotten it together to use it myself.... Hence the ???

Unusual portrait, really good. Do their bodys stand out a little more from the background on a wet print? :p
