I was just reading a book "Creative Black and White Photography" by Bernhard J. Suess and he mentioned testing shutters for accuracy and intimated that this was a valuable thing to do. He suggested a "portable shutter tester" from Calumet.
My question is: Is shutter testing something that is valuable to do? I have thre e new Schneider lenses in copal shutters. Is the device that he mentions valuabl e or does one use a local lab for testing? This was not even on my radar screen before I read this. Should I pay attention?
Thanks as always!
