When foggy mornings arrive, I run out with my Infrared camera and a couple of different lens filters to capture some fun colors.
Morning fog can be dreary, but Infrared Chrome adds a new dimension to the scene. It picks up anything with chlorophyll and makes it a gorgeous hue of reds. Dead trees and bark show up as black and anything to do with sky-water, shows up in a blue hue.
I was in the valley fog of the Kickapoo River. Fog is more common here along the river most mornings.
Below is another shot with the 665nm on a foggy morning. The filter sees through the haze a bit better than a regular camera. I was intrigued by the spider web on the neighbor's rye grass. [This went along with my study of grasses!]
Technically I should have edited the clouds into a white color, however the humidity picked up the blue hue.
Normal....
When WWII began, militaries deployed the use of infrared aerial photography as they did in WWI. The unique ability of IR to differentiate false greenery used for camouflage from real, live foliage (known as the “Wood Effect”) was a powerful asset, and many used it in hopes of gaining every advantage possible on the battlefield. However, a new paint that could mimic the Wood Effect was developed to render this photographic method useless.
A new tactic needed to be born to get back the upper hand. Kodak and the US Military worked together to create a false color infrared film — Aerochrome III Infrared 1443. With this new color IR film, the chlorophyll in plants would photograph as hot pink instead of a snowy white, making camouflage detection possible again without the Wood Effect paint getting in the way.
