I have red thru the information about the Bosscreen in the LF homepage. I realiz e the screen is superior to the normal ground glasses and "improved" ones like beattie and brightscreen in terms of grain and contrast.
Could anyone enlighten me on the following points on using the Bosscreen on a 4x5" camera:
1) Should I use an additional fresnel with the Bosscreen with a 90mm lens ? How much does the view vignette without a fresnel ?
2) How much brighter it is actually, for example compared to a basic ground glass and/or a fresnel ? (I am having problems with heavy vignetting with the 90mm on the standard "fresnel ground glass" of my Wista DX)
3) What about compared to a Beattie ? Does anyone actually use a beattie or brightscreen screen on a 4x5" with wide angle lenses ?
Any info and/or thoughts would be extremely welcome!
