I just have to take a picture of the front of my house. It has two trees and a telephone pole in front of it. When these slides are projected, the trees and telephone pole stand out from the house like 3D. I think it has to do with contrast and shadow detail more than anything to do with focus. The good Leica lenses just put more on film. Regards, Robert At 01:50 PM 12/26/98 -0700, you wrote: >George, >What you say it partially true.
