Tarun Bhushan submitted this photo taken with an Olympus E-510 with an exposure of 1/100 sec at f/5.6 and an ISO of 200. While the colors of fall can be beautiful, try shooting something unconventional. To me, this photo isn’t very interesting, it’s just your typical here’s a pretty leaf picture. Perhaps a macro close up of the leaf itself would be nice or a photo of one red leaf amongst an area of green for some contrast. Regarding the color of the photo, I would check the color balance and adjust to your monitor if it’s calibrated.
