P3D Great small external level

[Paul Talbot <ptww@xxxxxxxxx>]

Yesterday I stumbled across a keychain level that
looks great as a level for stereo cameras.  It
measures 1-5/8" long x 5/8" x 5/8" and comes on
a small keychain ring.  I don't use a level all
the time, but when shooting on a tripod I think
it's easier to have a level on top of the camera.
(Especially when shooting with a Sputnik.)

I've used a small circle level and a line level
(sitting on the camera, not hanging on a string)
before.  But I have sometimes ended up out in the
field before realizing I hadn't brought one of
them with me.  Now I can be sure of having a level
handy whenever I have my keys in my pocket!
