    Re: LED UV Light Box: Build Your Own for Under $150

    Thanks for resurrecting this. It is getting harder all the time to find "proper" fluorescent lights of any kind. I'll continue to use my 6 x 18" bug zapper bulbs until I can't, but it's good to...

    Re: Which are the fancy lenses??

    Sounds like a reasonable approach. Once you get going in 4x5 you might want bigger contact prints and then those lenses will seem a lot "shorter." I got to borrow a 75mm (I think that was it) for a...

    I'm amazed. I've snapped a few iPhone pics through my scopes and some friend's scopes but I never thought to mount an 8x10! Amazing!

    Or we could sort of go the opposite direction: lenses repurposed for LF, i.e. close-up "filters" or positive meniscus lenses, perhaps with Waterhouse stops, old projector lenses, some are Cooke...

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

    I don't think coating with nitrocellulose would work. It is waterproof once dry, so you would not be able to develop the films. Maybe it could be used as a protectant after development, but the dry...

    Re: Show off your camera!

    I got started in LF fairly similarly, in my case it was a Busch Pressman D. The old press cameras can teach people a lot and are a lot of fun in their own right.

    Vaughn,

    The low tack adhesive spray makes a lot more sense to me than always pointing the camera straight up!

    I have this tendency to go to the most complicated process I guess.

    My vision? Tough. I’m trying to decide what the compelling reason is to do ULF when 8x10 or cropped 8x10 seems like plenty most of the time.

    ULF film flatness idea

    About a week ago I took the "heart" out of a graphic arts camera at a print shop dating back to 1946 that is going out of business---the camera is, I think 1970's or 80's vintage, but I really don't...
