Description:
Bright Accurate Clear
I make ground glass for a variety of camera and formats.As far as brighter is concerned,over the yesrs I have measured a variety of focusing screens and compared them to the originals.
This includes new acid etched,hand ground,Boss Screen,current hand-ground glass,Beatty and Bright screen and my own.I measured with a Gossen Luna Pro and a probe from edge to edge.
There is a half-stop difference from old glass in most cases.Acid etched is brighter by a stop-BUT-you loose the contrast that is in hand ground glass that makes focusing easier and faster.
The only significant improvement comes with using a fresnel-BUT-it makes focusing with wide angle lenses and a loupe a real chore as the lines of the fresnel become increasingly evident.
In the end,I use a three step method which is actually different than that of any other offering.It combines everything I have learned about ground glass and to get the most amount of light with the most amount of contrast by chemcial and hand-ground methods and includes a final coating,as well.
