Re: Use of X-ray film: technical discussion with example images
Well, I am getting the feeling that the quality control in manufacturing of Fuji Xray film is lacking. Over the past 4-5 years I have purchased five 100 sheet boxes. All have been 8X10 but my most recent is 7X17. I got a very similar defect in one of the 8X10 boxes as I am now getting in my 7X17 box.
Shot and processed this morning trying out my home-made back that I mount on my 8X10 camera:

The negative is covered with little dots of minus density. I purchased this box new back in December and recently opened it. It has been stored at room temp.

Both bad boxes are Fuji Super - one is HR-T and one HR-U, purchased several years apart. Both are the Green sensitive.
So, my experience with Fuji Xray film is not very good.

Did it come from eBay?
99% of my X-Ray bought in date from ZZ a major X-Ray products for 'real' medical X-Ray supplier

That's interesting. I've shot a lot of the Fuji and never seen that. Out of curiosity, what developer?
Re: Use of X-ray film: technical discussion with example images
Are you sure it's not caused by you? I ask because I had similar flaws with Ektascan. I was using Obisidian Aqua and semi-stand at the time, citric acid stop, and Ilford Rapid fix. I switched to D-23, and reduced fix time to one minute. Problem solved. It could have been caused by the OA, and semi-stand, I don't know...
Re: X-ray Film example and comparison.
Hi,
Does anyone know if they made film development hangers for full plate (6 1/2 x 8 1/2) film?
My usual development for X-ray (4x5, 5x7 and 8x10) is on hangers in tanks. Its the only way I avoid scratching the film.
Thanks, any help would be greatly appreciated.
Cheers

I am sure it could be something that I am doing. I will just have to experiment...I guess. Could be fixing to long - like 4 minutes...? Just a water stop-bath.

Adox Rodinal 1:100, 75° for 4.5 minutes.
Re: X-ray Film example and comparison.
They must have, but not for USA
I too have looked
Perhaps cut some down, tiny cutting wheel
It can be done
