Ground glass for Ebony RSW45

[macmx]

I have an Ebony RSW45, but shoot mainly 150mm and 120mm lenses rather than wides, which is the camera is built for.
After looking through an Arca camera, I am getting a sense that I could get a brighter/better image of I replace the standard ground glass for Ebony with something else.

Does anyone know which ground glass screens would fit the Ebony and have any suggestions?

Any help is much appreciated. Thank you.

I’m pretty sure the Chamonix screens fit the Ebonies. The original Ebony screens were pretty good though, and I don’t think a standard Chamonix screen is any brighter. Both are plastic combined screens with built in fresnel with a clear cover glass and very sinilar.

If you measured the aperture in the wooden frame that holds the ground glass, i'm sure you'd find replacements, though how suitable they'll be is open to your own assessment.

Bill Maxwell made screens for Ebony, though to be honest, the Ebony screen with the built-in fresnel is better IMHO.

I'm not sure if Boss-screen are still available, though i use one in my Linhof.

Was cleaning out closet and found two screens for Ebony 4x5:
- one marked original
- another marked "Ebony w/a (wide angle) fresnel" - I think this was purchased from Ebony for wide angle lenses.
both from 2001.

Let me know if of interest.

Look for a Bosscreen, see some explanation here:

Ebony GG Screens were regarded as some of the best.

I would suggest a Fresnel - but with 120 and 150mm lenses, there is not much point.

Might I be bold enough to suggest a darker Darkcloth.

The BlackJacket ones are excellent.

I replaced my Ebony GG with a Satin Snow GG - distinct improvement, and also permanently removed the standard fresnel screen. I hate those things; and worse, condensation collected between the GG and fresnel on cold mtn mornings.
