    Beattie Screen for LF?

    Is anyone using a beattie screen for LF work? If so, what is your opinion of it? they advertise +4 stops brightness in the viewing screen. That would be nice for the times I shoot in dark conditions.

    I installed one on my 8x10 'dorff several years ago. It helps. The good news is it's brighter, the bad news is it's brighter head-on only. Like a cheap lap-top screen you must be on-axis. It also helps if you are back far enough to use binocular vision on a single spot. This usually leaves out those of us over 45. However, my optician and I have managed to stay one jump ahead of the aging process, and if I'm wearing the correct glasses I can get the best out of the Beattie screen. It goes BEHIND the ground glass (closer to YOU), with the engraving away from you.

    Are you saying that it isn't much help when focusing with a loupe? Or am I confused by your back far enough for binocular vision comment?

    I have one installed on a medium format Tlr and there is a big difference. Pricey, but good.

    I use one with my 4x5. It does help even with a loupe. Although I find myself backing up about 2ft or so get get a better look at the whole glass.

    Hello! I have a Bright screen on a 5x4 Sinar and it has made all the difference when using the slower lens, however as previously stated generally you have to view head on.

    I have always used a loupe for critical focus. My eyes are too old to look close enough at the whole 4x5 to focus. Does anyone else ever wipe the ground surface of the glass with a very thin coating of WD-40. It makes the image a lot brighter.

    While I usually use a loupe, I don't always. For initial focus, without the loupe, the Intenscreen is best viewed head-on--so much so, that with your eyes close to the screen the distance between your eyes (parallax) lessens the brightening effect. As you move away from the screen the parallax decreases and the brightness becomes more apparent. When using the loupe, you only use one eye, so this becomes moot. On the other hand, when using a loupe, the increased brightness is much less apparent and I doubt if you could appreciate 2 stops of brightness, let alone the advertised 4 stops. You might do just as well with a higher quality precision ground glass.

    Thanks for the info. I have old ground glass on all of my LF cameras, and am still trying to figure it all out. The main thing I am looking for is a clearer (not necessarily brighter) view when I stop the lens down and do final critical focus with the loupe. FYI, I'm using a Toyo loupe to focus.
