    At what guessamation was the ASA? Nice images.
  23. Re: Use of X-ray film: technical discussion with example images

    At 1:3 you will need 15-19 min developing time @ 68 Degrees F. Agitation every 30 seconds. If 1:1, you will need 7-9 minutes. Same agitation, open tray.
    In a container be careful. X-Ray film will...

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

    Yes, X-ray film was used as a "paper" and a normal enlarger was used with a negative. You get a positive image. I've done this many times.

    No it is the whole negative. I cut it from a much larger film,the edge on the right is a little off plumb for being cut in the dark.
