Aren't we forgetting the most likely source of the vibrations? - the
wooden deck. I've shot from many different types of wooden structures - all
of them have had quite a bit of movement from any human movement upon them.
There's not much you can do about a wooden structure except stay very very
still for awhile before clicking the remote release. If possible, get off
the structure. My breathing and my heart beating actually produce movement
all the time. Shooting from a cement platform is quite a different thing.
There you could actually assume any vibrations are caused by the tripod
support. Another thing - at least here in Japan, is that the earth itself
moves - yes folks, the earth is a living thing, it moves. Not to mention
humans and machines are beating on it all the time. Sometimes it moves a
great deal, and we call that an earth tremor. The rest of the time though, I
believe there is some movement, and it's amplified by a wooden structure.
Depending on where the structure is located, movement can be induced by
things like heavy trucks. In Toronto I remember well residents complaining
about the new street cars. They are very heavy and cause much vibration in
housesd a long long ways from the actual tracks.
Hopefully, the earth is a bit steadier where you live, but don't expect
it to stand still all the time.
