  Simple signal-propagation effects make receding objects seem contracted and
approaching objects seem elongated. These effects are theoretically
photographable, and are proportional in strength to the frequency-change in the
object's emitted light. In a one-dimensional version of the "barn-pole"
experiment, a "moving" object's photographed image can appear doubly
length-dilated according to fixed-aether theory, but only singly length-dilated
according to SR. This expected difference might be charitably described as a
form of photographable Lorentz contraction.
