    The spectra I've seen show a response well into the UV. However, the focus will be different and indeed it may not get through your lens.

    I googled a few of my lenses and no one seems to have tried UV photography (and posted online about it) with them. Are there any pieces of information about a lens that would allow me to anticipate its UV transmissibility?

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

    Ok just to get back to picture taking. I thought I might try something new. I have now dabbled a bit with nd10 filters using xray and it works pretty well. The company that makes the ND fIlter I purchased also makes star filters, these are designed for digital, so I thought it might be fun to see what the effect would be using xray film. Please excuse the quality and the out of focus pic, but I was mainly interested in effect.

    Hmmm... Made me think...

    Why not just keep experimenting with developers, dilutions, time and agitation methods to get the contrast where it needs to be to print on the desired paper? That is what most of us have done more than once in our lifetimes to get the desired results. What works for me may very well nt work for you.

    Next time use less developer. You are so wasteful! Kidding!

    Nice job!

    Since 2,5ml and 270ml in rotation work, I don't believe that either developer or water are required for Xray development - it must only be the movement :-)
