This is a composite picture, with two negatives printed simultaneously on the same paper.
The picture of the Moon is on a 9x12cm sheet of film, which is projected on the baseboard of a 4x5" enlarger (at a 4.5 magnification), and onto an 18x24cm sheet of film containing the clouds (which is contact printed).
With the same exposure (and some minimal dodging and burning) the two negatives are combined into one print.
Both negatives are Fuji AD-M xray film.
They were both shot with the same camera, a Kodak Master 8x10" view camera, but on different dates.
The Moon was shot with a Symmar 360mm lens on May 29, 2018.
The clouds were shot with a Fujinon W 180mm lens on June 14, 2018.
Both negatives were developed in Rodinal (RO9) at 1+100 dilution (1lt solution in a 10x12" tray), at 24C, with intermittent agitation.
The Moon for 10'min.
The clouds for 12'min.

Great job. I hope Steven R sees this.

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

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

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!
