Thanks for all the comments. I really enjoyed reading them.
The photo is not really a X-ray.
I took the baitcaster (fishing reel) and removed the side plate.
I then removed the spool from the inside so I could see the gears.
I set the shot up. Turned the lights off.
The room was pitch black. I set the camera self timer. The shutter opened for 6 seconds.
Then I took a manual flash that I just held in my hand and flashed the reel from one side. Then I removed the side plate from the baitcaster and flashed it from the other side. All before the shutter closed.
I used paint shop pro 8 one step photo fix to auto adjust color and sharpness.
Then I used the "Negative Image" button to get what you see now.
I did try to place it on a diagonal as I thought it would look better with the fishing rod, but I just could not seem to make it work without the reel being so much smaller looking in the photo.
I took about 8 photo's of the reel and this one turned out the closest to what I had in mind.
There are a number of things I would do different next time for a photo like this.
I'm very happy with my 61st place being this is my first challenge.
