    Ah yes, after I posted I got to thinking that the beam splitter would have to be thin to minimize optical effects but a large thin mirror would probably sag or warp. and a small mirror is probably much more available in stock from some suppliers.

    Ummmm.....what exactly are the advantages of either over a gg back, especially in a studio?
    I steal time at 1/125th of a second, so I don't consider my photography to be Fine Art as much as it is petty larceny.
    I'm not OCD. I'm CDO which is alphabetically correct.

    Fair question. I don't understand why the OP is obsessed with trying to improve on technology that's been under continuous development since the 1850s. He doesn't seem to be aware of studio photographers' best practices. And he seems to have joined the wet plate cult. Wet plate was completely replaced by dry plate, which in turn was replaced for nearly applications by film. There have to have been reasons.

    Hey John Kasaian, Thanks for your question.

    I feel the question could be answered with a question. Why does a full frame DSLR have a viewfinder? Even in the studio you would use the view finder or LCD screen.

    I think being able to see exactly what the camera sees could make things work more smoothly in terms of flow.
    And with a reflex viewer it would be even better.

    Being able to focus closely before exposure would be great. Yes, there are those head stand designs from the 1800s but I'm not here to make mug shots/passport photos. The poses I will attempt you
    wouldn't be able to hide the head stand.

    ~~~

    Thanks Dan for your comment.
    I'll look into these best practices as you mentioned hehe
    If you have any more advice or opinions that are constructive please share

    Whether that makes sense depends on what problem one is trying to solve by going to a reflex design.
    How about a pellicle mirror? You'd give up a stop or so of light, but you wouldn't need to move it.

    On the subject of pellicle mirrors.. apparently Saran wrap "works ok"? Maybe this would be your cheap 8x10 SLR solution.

    Thanks Plywood, Robert and domaz.

    Interesting engineering solutions!
    Thanks.

    When I get my mono rail camera (I only have a field camera) and start playing around.
    I'll think about these solutions!


    Enjoy the new week y'all
