I'm new to LF after several years of 35mm and 645 experience. One of the adjustments I'm struggling with is the relative brightness of the ground glass. In researching this, I'm interested in knowing if there are any comparisons of the "bright screen" products. If anyone has experiences with the various brands, or knows some to be superior to others, I'd really appreciate some guidance in making a choice. I'm not soliciting endorsements, just information. Many thanks for a wonderful resourse for a beginner like me.
