I picked up a used Contax T2 yesterday.  I thought I knew how to use it pretty much without reading the manual.  Half way thru the roll I thought that the exposures were all messed up.  Finished the roll and to my absolute amazement the developed film came out pretty good.  Turns out that reading the manual can give you insight!!  Here is one of the shots from the back yard that I really love

This was a pleasant surprise
