5X7 X-Ray Bargain
Fresh in date film
ZZ sells 7X17" 2X 100 sheets for $53 plus shipping
I cut into 300-5X7" 2X films making my cost 25 cents per 5X7 sheet
I assume $53 film, $22 shipping = $75
I cut one sheet at a time, and only what I need at the moment
The 2X7" leftover has many uses, including testing fixer clear time
or make a pinhole pano

hard to say which specific film they're repackaging, but it's double sided orthochromatic, so fuji hr-u green would be similar but at a more useful 50-100 iso. i've bought from these guys before. https://www.ebay.ca/sch/xrayexpress/...1&_ipg=&_from= a box of 10x12 would give you 600 4x5 sheets at 8 cents each.

Here in Europe we only have 18x24cm mammo single sided films. Where do you buy your 8x10 mammo films?
Thx in advance,
Re: Use of X-ray film: technical discussion with example images
Maybe nowhere
I got a camera to match

I have been buying 18x24cm Mammo film here and there on Ebay for lower money. And 18x24cm Sinar Norma era film holders :) I have 600 sheets on hand. I'm setting up an 8x10 Kodak Hard Rubber Basket line for processing. Going to start with DK-50 'cause that is what I have in quantity, along with the replenisher. Should make nice RC VC contact print work prints for starters. I followed Tim Layton's lead and made a variable contrast light source that fits my large Multigrade filters. Split printing these XRAY negs will be fun.

Re: Use of X-ray film: technical discussion with example images
The first X-ray film I got was via Forum members. This is medical stuff. Then I got a huge amount of Foma Indux R4 4x5, this is industrial use film.
It seems to be 6 ASA at best. I am still not altogether sure of that because then I was shooting at around 2:00pm on a winter's day (January) & the sun was already low.
I think that I have the right development time...
A non-colour sensitive film does not seem to have a fixed 'speed'. I'm thinking approx 3 ASA when the sun is low, as it was that January day. Then maybe as high as 10 ASA at mid-day in the summer months.
It makes a shoot interesting. Thank goodness landscapes don't move.
Re: Use of X-ray film: technical discussion with example images
Your tests correspond with my research. I have not used that type, but it is still used for testing metal and more
When we X-Ray people we ask them to not move, thus higher speeds are useful
