    Re: Brass lens suggestion for a 4x5 camera

    Hi Jimi
    My camera is not a sliding box I use the rack and pinion to focus.
    It doesn't focus as close as I'd like for still lifes etc.
    I'm thinking of building some kind of step out mount for close...

    Thanks for the info. I found a page at http://antiquecameras.net/rosslenses.html that shows what appears to be original Ross advertisements.

    Re: Brass lens suggestion for a 4x5 camera

    G'day Jimi
    I recently acquired a smaller brass lens and built a 4x5 box camera to fit it to.
    These brass lenses, though physically large, have quite restricted coverage. I was planning on buliding...

  5. Re: Alternate History of Photography: how early could it have been invented?

    An interesting question Maris. But I'd turn that around and ask, if we never had chemical based photography would anyone have ever gotten the idea to make images digitally, or at all?

    Re: How focal length affects aperture?

    Because, in your diagram, can you see that the camera body for the 300 mm lens will need to be, physically, twice as long to bring the image into focus at the film plane.

    So, the same amount of...
