I am not too happy about Fresnel ground glass that is installed in my Linhof Technika IV. Nothing seems to snap into focus, and small details are lost. I am considering replacing it with regular ground glass. (I had a brief experience with Technika III with regular GG, and liked focusing much better.)

I can easily buy ground glass, but can I install it correctly? Mechanics looks simple enough. My question is: How GG should be aligned? What precision is neccessary? I have digital caliper to measure depth t o half a thou. Or should I delegate the job to a professional?

Oh yeah, one other thing. Can anyone tell me the difference between regular Linhof screen and the one with micro grain?
