The fall colors are vibrant this year due to the heavy rains we had this spring. I don't know if we will make it to the mountains this year, but I bet the colors up there are gorgeous.
I used a Moose's Polarizing filter with my Tamron 90 mm macro lens for this shot. The polarizer really enhanced the blues, as they are meant to do, and the reds were accented by the the warming filter that is built into it.
