  1. Re: How to finish, wash and dry fibre paper prints for exhibition and sale

    I looked through some prints I dry mounted on cheap 4-ply board 35 years ago. Yes, I had no money and didn't know better at the time.
    The prints are pristine and as good as the day they were made....

    Re: Where do y'all record your photo data ?

    I used to record film exposure data but haven't done so for years. Why?
    It turned out that all my film exposures were the same, namely full exposure, arrived at by a spot metering protocol that...

    Technically perfect? No, a better target is "good enough" provided it is genuinely good enough and not just laziness.

    Re: Fujinon 300mm & 360mm W puzzle

    I use a Fujinon-W 300mm f5.6 lens as standard on my Tachihara 8x10 camera. This lens appears to be multicoated and has the inside lettering. The serial number 450xxx puts it as late 1970s or early...

    Re: Depth-of-focus problem, enlarging lenses

  13. Re: DIY ULF Lenses - 3D printing resin, epoxy casting or sand casting?

    I am a sometime amateur astronomer and the subject of lenses has been fascinating.

    Just for the record and just for interest large diameter lenses exist and the place where they are most often...
  14. Re: DIY ULF Lenses - 3D printing resin, epoxy casting or sand casting?

    High aperture number? Yes. About f45 for the example I quoted. The limitation of the "opposing dioptres" approach is the scarcity of large diameter matched pairs of lenses.

    Making ULF lenses is going to be steep engineering challenge but assembling a ULF lens from existing components can be easy, quick, and cheap. Here's what I would do:

    Re: dirty film / filtering liquids

    Check the fixer. If it is slightly cloudy it is "sulfuring out" and precipitating millions of tiny white specks of elemental sulfur. And these specks, being insoluble in water, don't wash off easily.
