    HRU test 2 Norma Handy Sinarsix MicX by Nokton48, on Flickr

    Same scene as previously but one stop additional exposure
    EI of 25 1/8 F11 Key Day Center Filter Seems to have more highlight and shadow detail

    Negative suffered some damage as film was mangled in the Graphmatic sheet holder. I'm switching to regular sheet film holders.

    What kind of times are you getting with the Microdol-X on average? When do you first examine the negative?

    My safelights are very very safe and I watch the films as soon as they go in the dev. Yesterday with HR-U the image came up to the point I could see something after three minutes.

    I set my time to eight minutes each time as a start, sometimes I pull them. With these Makiflex negs ^^^ I left 'em for twelve minutes and they look pretty good.

    If overexposed these films seem to come up quicker? I have had some come up in two minutes.

    HRU Fixing Step Dental Clips 1 by Nokton48, on Flickr

    I've decided to use these Dental Clips I bought on Ebay, to hold down two sheets in the Cesco flat bottomed trays, and keep them off the bottom, and keeping them from moving around (which scratches!)

    Here two sheets are in the TD4 Fix

    HRU Wash Step Dental Clips 2 by Nokton48, on Flickr

    Here the two sheets are moving into the wash tray. This has caused a lot of grief, if a sheet touches ANYTHING it is scratched with HRU.

    The sheets are well distanced, off the bottom, and can get a decent wash with getting scratched.

    HRU Dry Step Dental Clips 3 by Nokton48, on Flickr

    When I go to the dry step, I move both clips to opposite ends. So the water can drain off properly.

    I have made three runs this way, with only one scratch (my fault).

    Getting perfect sheets with HRU no defects is not an easy matter. So far I can see no reason to continue tray processing in thos way

    I thought that is single side film?

    How does it scratch face up?
    where is the monolith

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

    I have HR-U which is double sided.

    I also have Kodak MIN-R which is single sided. Both are prone to scratching.

    I'm doing two 4x5 sheets at a time and they tend to move around in the tray. If they touch ANYTHING they will scratch!

    The clips keep them from floating around and banging into each other, especially in the wash tray

    If I am diligent I get zero scratches. 5x7 I would go single sheets in a tray, that is a different animal.
