High Explosives

Reverse image: a Boeing B-17 flies over trees in Discovery Park in Seattle, May 2014.

I recognized the roar of her four massive, distinctive radial engines before I saw her and I got a shot of one of the few flying B-17 bombers in the air. 

I reversed the values: the resemblance between a negative image of trees and bomb explosions is interesting. My first thought: trees grow like explosions and produce oxygen. Bombs burn,  and consume it. The organic looking structures resemble one another, distinguished by, among other things, the Amplitude of Time.
