I saw A. MOrris's post on this subject on another forum, and could
barely restrain myself from answering. The only thing that did restrain
me was an immediate inability to answer it civilly. With the long focal
lengths and slow shutter speeds he cited, there was a strong probability
that his heartbeat would introduce unwanted movement. the only saving
grace is that this technique may, repeat MAY, reduce vibration of the
wood deck, but I'm afraid it would introduce movement elsewhere. I
looked at Mr. Morris's images on his website, at least his nature ones,
and could find little evidence of stellar lens stability and sharpness
of image. They were good, but not excellent, in the sharpness
department, leading me to think he needs to reexamine his technique.
