Great pictures! They reveal an artist who profoundly appreciates the natural world.
Great blog! The content is ALWAYS valid, concise, informative and thought provoking.
Many thanks, Tony.
You are wished a grand 2019.
Red and white – definitely signs of global warming.
A whole lot of trees that appear blue in the bottom pic.
blame CO2… :)
You can tell from the shadows that the sunlit side of the trees is at about a 135 degree angle from the photo POV. Most of the light illuminating the side of the trees we can see is scattered from the atmosphere.
Blue light is more highly scattered by the atmosphere. You can see the result of this effect clearly in the color of the snow in the tree shadows, and in the shady side of the ridge.
That is ridgy didge (an Australian slang term for “that’s right).
Then explain why not all of the trees from which the drone is down sun do not have that blueish cast? Perhaps dispersion of the trees themselves. It appears those that have that color are in the areas of thickest growth.
Thickest growth=least passage of direct sunlight=deepest shade=higher proportion of scattered (blue) in the mix, I think.
The algorithms which produce all of this are an unknown to me, as well.
And in the pic above that, the colour of the road appears quite “red”
Any suggestions why ?
That road is blacktop. I think it looks reddish because of in-camera color correction.
Orange-red ( the color complement to sky-blue) seems to be added everywhere, including shadows and snow. Things which normally have some red (like the brick building with the semi-circular drive) are kinda day-glow, too.
Actually some asphalt one finds out west does have a reddish tint.
For that matter, they use a salt/sand mix in Los Alamos for anti-ice. That would not make the dark red brick and vehicles into day-glow orange. It could be both.
Everything in the picture that is not white or blue is visibly tinted orange.
Now THIS (as opposed to the Gatwick, UK fiasco) is the way to use a drone! Congratulations, and a Happy New Year!
