    Re: How to open old Gralab 450 for repair?

    I got it fully disassembled, cleaned switches with Electronics Contact cleaner. Looks like they are working much better now.

    No, I didn't expect them to give me advice on fixing their timer :)

    The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.

    Re: Certificate Expired

    You can look into using LetsEncrypt, it's free SSL certificate and you can setup a process where it's automatically renewed. Making it completely hands-off process :)

    Re: How to open old Gralab 450 for repair?

    I was able to gently pull those handles from rotational switches, there was no glue! 4 screws on the bottom - and I got it opened!

    I'm going to spray/soak those switches in electronics contact...

    It will cost about 2 or 3 times more to get them repaired by Gralab, compared to buying one from eBay :)

    No concern about this cleaner finding it's way inside the timer?

    Re: How to open old Gralab 450 for repair?

    Yes, that's what I'm afraid may happen :( There must be a way to do it, we just need to find a repair tech who knows how to do it :)

    Maybe heating it up can help with getting the glue to loosen up?

    Re: Portable Studio Portraits

    Really cool idea!!!!
  13. Re: Use of X-ray film: technical discussion with example images

    Ok, I'm going to give it a try as-is, no bleaching :)
  14. Re: Use of X-ray film: technical discussion with example images

    For people who are removing extra emulsion with bleach - when is the best time to do it? Before or after you expose and/or develop it?
  15. Re: Use of X-ray film: technical discussion with example images

    Do you know if it has emulsion on both sides or not?
  16. Re: Use of X-ray film: technical discussion with example images

    So I'm planning on using Rodinol for my Fuji HR-U developing. What should I use as fixer? Some people here mentioned using hardening fixer. Is that what everyone is using?
  17. Re: Use of X-ray film: technical discussion with example images

    Argh, wish I saw that earlier! Now I'm stuck with 100 sheets of double-sided green Fuji HR-U :)

    I've learned about how X-Ray film works from this Instructable, interesting read:

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

    Does the second emulsion interfere with printing? Contact or enlarger prints on B&W paper.
  19. Re: Use of X-ray film: technical discussion with example images

    Double-sided? :( I was hoping to avoid that. How are you dealing with this? Are you bleaching one side?
  20. Re: Use of X-ray film: technical discussion with example images
