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

The blue will not wash out. It's base fog.

I went ahead and bought a 100 sheet box of green sensitive double sided 8x10 from zzmedical, mainly because it was the least costly option they offer. I cut some into 4x5 and shot it and developed it in Rodinal and liked it. I also enlarged some 35mm negatives on to it to create B&W positive transparencies, which came out way better than I expected. Strangely the second batch I processed came out great with the exception of having a noticeable blue tint. What is causing the blue tint, and does it mean I didn't rinse it well enough? Thanks.

What is the function of the base fog, and is there a way to minimize its effect?

I think it's just the color of the base material, isn't it?

If so, I don't quite understand how you had two different results between batches.

The first batch seems lighter. In any case I should clarify that I am speaking of the positive transparencies I created. My main objective in posting was to say that I am very happy with the new experience of trying X-ray film.

Thodoris that is an excellent montage, you can’t really tell it is two different negatives.

This is a composite picture, with two negatives printed simultaneously on the same paper.

Wow. Just wow.

It's actually the color of the blue polyester base. All x-ray film uses this substrate. It makes it easier for the radiologist to read.

Thanks for the love guys, I really appreciate it!
