I'm guessing you want some sort of digital loupe to help focus the camera? I don't think that kind of thing exists, but you might be able to rig something with a small digital camera and macro set-up. Kinda clunky. Something I sometimes use to help focus in dim conditions is a ball of aluminum foil that I will include in the scene (f it is not too far away) or have the subject hold. The foil will be brighter and have sharp edges that are easier to focus on.
Why lug around a bunch of silly electronic stuff in addition to a large camera along with tripod, film holders, lenses etc too? It won't help you.
That’s a good one!are you just so full of hot air that you naturally levitate and can put your head in any position around your camera, regardless of how high off the ground it is set?
Just go to an Edmund Scientific Industrial catalog and drool over the seemingly endless possibilities. But remember, most "machine vision" is fixed distance, fixed focal length, and fixed aperture. But that the sheer siliness of it is that an actual groundglass is going to give you a bigger viewing surface, and without the optical penalty of a bunch of intermediate conversion. Makes sense if a robot camera is being sent into a hazardous location, but not for any normal application I can think of. It's all been done before anyway, at considerable expense. And of course, if you're going to bother will all that extra tech, why even shoot film rather than going straight to digital capture? Reminds me of a franchise model selling a completely automated and robotized method of making and selling pizzas. The equipment worked fine, but the pizzas tasted terrible!
