Heck, now we have 3 X-Ray threads, since I started Tiny Format X-Ray thread, which needs a bump and practitioners. Can't post those here.Quote:

My compliments for the clarity of your video.Quote:

Do you know which optical density you can reach with a single layer?
I agree Salvatore, unless it is just for scratch reduction, I would think two sides would give greater density. I eventually want to use my negatives to do salt and albumen printing, I think the added density would make for better prints.
Very nice work, especially for a first attempt.Quote:

about half a sec I think. It wasn't soft enough and the sitter hated it, I now have a couple of softies added to the arsenal.
In terms of what x-ray film is designed for the reason that there are two sides is specifically to allow for less x-ray exposure to be needed in order to expose the same image, so the double density helps to reduce the amount of x-ray radiation that is needed in order to get a decent x-ray.Quote:

There are two things to keep in mind, one thing is that most people when shooting such large film or not enlarging it, they are simply contact printing, so "clarity" isn't ass necessary, however if you're cutting it down down or enlarging it in some way, then you'll want the image to be sharp, so it's best if you face the film toward the light, and then strip the "back side" because that second layer has had light passing through the base material and scattering the light ever so slightly, this COULD cause fuzzy edges when enlarging.
So I guess it depends on what you want to get out of the film really.
Sorry if that was a scattered thought, I hope it was sort of clear.
