I am new to the LF cameras and have recently purchased a Toyo 45C. I have many q uestions that I sure will be answered during the use of the 4x5 but at present I am having problems focusing with such a dim image on the ground glass. I have a Ziess 150mm, f3.5 lenses set in a Compur shutter, very old lenses but is clear and scratch free. My question is, are there other types of glass that will give off a brighter image than the stock ground glass back with the grid, 6x7 & 6x9 format lines??? Any help would be appreciated...
