  1. Re: Please help me identify the source of this light leak on my negatives.

    I'm starting to think UV or IR light coming from some source. FP4+ doesn't extend quite as far into the UV as HP5+, and it's slower speed.

    If you've got a digital camera, try taking a really,...

    Re: "Crown" -brand Sheet Film Holders.

    The ones shown on eBay don't appear to be 3D printed, rather some form of injection molding. There's no distinct line patterns visible anywhere.

    Doremus has the best explanation so far.

    Personally, I view the optical system as two cones, meeting at a point in the middle of the lens/shutter unit, and extending out in both directions from...

    Re: Intrepid 4x5” - new model due.

    Am I the only one who has a pet peeve about the bare threaded rod sticking out the front? I don't mind that it's unconstrained (common in 3D printer Z-axis assemblies), but they could have cut it an...

    OK-- I have two holders, labeled "1" and "2", and each side is labeled "A" and "B". I take four photographs, in holders labeled 1A, 1B, 2A, 2B. I place those two holders in a dark bag, I remove...

  8. Re: I'm not sure if it's a popular size, but can I get some 5x7 camera recommendation

    I'm surprised no one has mentioned it, but the Chamonix 5x7 is right at the top end of your budget. They're very nice-- lightweight, well built, and Hugo does a nice job supporting them.

    Re: New Computer Time...

    This is *not* a good time to be building a PC.

    Component prices have jumped in the past 12 months, stocks are low, and video cards are going for ridiculous prices.

    Re: Chamonix 810V Back Orientation Mistake?

    The bail is fixed to the part of the back that you take off and rotate-- so if you had it set to load from the bottom, the bail should have been operating from the bottom as well. Having no actual...

    Re: 2 sheets of film in the same holder?

    I would think between the refraction index of the film base and the extra distance to the second sheet of film, you'd get a very poorly focused image.

  26. Re: Looking for advice/guides on digital to film (not inkjet)

    As far as I know, your only real option if you want to avoid inkjet / dye printing, is to project the digital image via some form of display, and take a photograph of that image.

    But I don't see...

  28. Re: Which would be easier to build - 8x10 SLR or TLR?

    If this is for studio work, wouldn't a parallax-corrected viewfinder do as good a job? Or do you mean to correct critical focus right up until the shutter trips?

    No, I'm afraid that won't work. The rear of the Tele-Xenar is 86mm, and the opening in the 45N-1's standard is only 84m... :)

    Sorry, I wasn't clear-- I personally, think it's a bad idea on either camera.
