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

    Mind … blown!
  2. Re: Use of X-ray film: technical discussion with example images

    FWIW, I store mine in the freezer, factory-sealed, until I'm ready to use it. Once I open it I store it at room temperature.

    Haven't had any problems so far.
  3. Re: Use of X-ray film: technical discussion with example images

    Based on previous posts referencing removal of one side of emulsion, yes.
  4. Re: Lightening the non-load: Dispose of Metz Mecablitz SCA300 or keep?

    I can endorse this supplier. Best cables money can buy. Also best place to find really obscure adapters.

    Re: Short Petzval

    FWIW, the longer of my 2 Petzvals has an adjustable iris. It is definitely a Petzval 2 doublets, cement in front, air in back.
  6. Re: macOS 11 upgrade discards printer/scanner drivers: replacements may be unavailabl

    Try VueScan. It's way better than the OEM software anyway.
  7. Re: Use of X-ray film: technical discussion with example images

    Get 2 of these bulbs and the socket adapter. Put them in a cheap clamp-on work light with reflector and point it at a white wall or ceiling.

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

    I bet those subdermal freckles are nearly invisible to the naked eye. That's one of the things I love about this film.

    I'm with you the 1st one is better.

    +1 on this.

    Was this from the manufacturer? A supplier? Or somewhere else?
  15. Re: Use of X-ray film: technical discussion with example images

    Mohmad, there are so many variables that our past experience may not apply to your exact situation with this film. Just as with regular film, it's best for you to do your own exposure tests and...

    Your link is malformed; it should start with "http://" but it starts with "ttp://". In any case, I was able to look at the datasheet & it doesn't provide a lot of useful information. The film is...
  17. Re: Use of X-ray film: technical discussion with example images

    I did not know about the latter type. You would probably get decent results with it after some trial-and-error.
  18. Re: Use of X-ray film: technical discussion with example images

    The developers used by hospitals are intended for use in their rapid development machines. I don't think you'd get the same result by, say, tray developing or developing in a daylight tank meant for...

    There used to be an article by Alex Timmerman on the internets somewhere in which he demonstrated that the exaggerated swirl you sometimes see in images made with a Petzval is the result of an...

    Only Ektascan & other single-emulsion x-ray films have anti-halation backing. And they are all on blue polyester substrates.

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

    The emulsion is much softer when it is wet, hence easier to scratch. But you can scratch it when it's dry too.

    I've actually ordered parts from Omega Brandess thanks to an earlier post by you, Bob. Good to know they have plenty of parts remaining.

    Re: Trial with the new B's 4x5 Developing reel

    That's why I fill and drain mine with the lid off and in the dark (or under red light for x-ray film). The real barrier is it's no longer being manufactured & the remaining stock of spare parts is...

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

    Apart from the pollution, I think you are farther north. Beijing = lat. 39.9042 N; OKC metro = 35.4676 N. So I'd probably need a slightly shorter exposure.

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

    Please order one or two of these. Use them with a reflector-type shop light pointed away from your work area (bounce the light off the ceiling). If you use two bulbs together you'll want this adapter.

    One of the nice things about the Gitzo 1542 (and others in the series) is they have a hook on the bottom of the center column. Carry an empty sandbag, fill it with rocks or dirt, and hang it from the...
