I take landscapes and architecture/interiors photos with Linhof Technikardan 45S. I don't have any problem composing an image with 135 lens. But it becomes almost "blind photography" when I use 75 and 55 lenses. So I looked at bright screens. B&H has Beattie intenscreens in stock and also there's Linhof fresnel ground glass. But is one of these going to help? And which one is better?
