Got a question for you guys with big ground glass. With a straight ground glass, do you have pretty good view of the overall composition? I am still in the process of putting my 11x14 together. For my ground glass, I went down to my local plastic place, and picked up a piece of frosted plastic. It shows a good image for focusing, but the hot spot, or perhaps I should say bright spot is not very large. I went down to Staples and picked up one of those 8x10 plastic magnifying fresnel page reader things. It was amazing what it did for the overall view. Its like it bulb was turned on. The combination was 100% usable, but its too small. So, do I dump the plastic, and get a piece of glass, or look for a big fresnel?
