In the Spring my Japanese Maple heralds the seasonal change with a bright red hue.... in fall, as it prepares for Winter slumber, it does the same... flora optimism.
I have a hard maple that was particularly pretty this year... almost missed it completely.
All shots with the Nikon D3 and either 14-24mm or the 70-300mm at 1000 or 2000 ASA (because I was too lazy to get the tripod out of the car). Levels adjustment and sharpening in Camera Raw but no color enhancement. All shots with exposure compensation of +1.
