Snapshots from a well-meaning amateur.
What is an "echoing reflection"? I am ignorant.
@Clint - just my feeble attempt at a poetic description of the "doubling" effect of the two panes in the double-pane window; two separate but close reflections, like a visual "echo"... There is no standard art or photography term known as "echoing reflection" - at least none of which I am aware, but then I am not exactly a recognized expert in such things, either... whew!
