    I would recommend spending your money on a good focusing cloth and a quality 4x or 6x loupe. While a Fresnel screen will brighten the overall image on the ground glass, it many times will not do so evenly. The concentric line pattern can often be confusing to some and interfere with accurate focusing as well. If you feel compelled to buy a Fresnel anyway, get an after market type that fits between the gg and your eyes. that way you won't run into gg/film plane alignment problems and you can also remove the screen if you decide you don't like it! Or, you can visit some of the threads on this forum that discuss other types of quality ground glass screens that others have used and investigate those. Boss and Maxwell screens come to mind, but again, others have posted specific comments on these. Good luck.

    Another vote for no fresnal. Just had a student take a view camera workshop this past week, and I found the fresnal screen in his camera just as annoying as I remember them. A well made hood-style focusing cloth and a plain ground glass is the way to

    You guys may have Superman vision, but I can't see to use a GG without a Fresnel screen. The best solution is to install one of the "bright screens" incorporating a Fresnel, such as Beattie, Maxwell, or Linhof's Super Screen which is sold cheap by midwest Photo (check the archives for their addresses). The other option, nearly as good and quite inexpensive, is to buy a Fresnel at an art supply story (or Barnes & Noble) and cut it to fit your 4x5 GG. As far as I am concerned using a GG without a Fresnel is medieval, akin to wearing a photographic hair shirt.

    If you decide to try a fresnel, mount it so that the ground glass is between the fresnel lens and the camera lens.

    There are exceptions, where the camera is designed to place the fresnel between the ground glass and the camera lens, but I'm pretty sure that this isn't the case with the Zone VI.

    Try the camera without a fresnel for a while. You may come to like a plain gg better. I used to think I needed a fresnel. After I worked without one for a month, I came to like the plain glass better. Now, I avoid cameras with permanetly installed fresnels. I hate fresnels.

    I use Beatties on all my cameras and like them alot. They have gotten me out of jams in low light shooting MANY times. Highly recommend them. Cheers

    Interesting conundrum...

    We admonish newbies to "check the archives" for relevant posts.

    Yet when they find one and respond to it, we chastise them for doing so.

    And if they start a new thread on that subject, they're chastised for bring up something that's in the archives.

    So what exactly are they supposed to do?

    Leigh,

    I wasn't chastising the poster.

    I was merely making him aware that he was responding to an eleven year old thread.

    So cool it already!
