This is a 3-exposure HDR image taken in Eleven Mile Canyon near Lake George, CO. The exposures were 1, 1.6 and 3.2 seconds using a variable neutral density filter.
The three frames were blended and tone mapped in Photomatix Pro 5.0. After blending I used the Camera Raw filter in Photoshop to make basic adjustments and reduce chromatic aberrations and color noise. I used the HSL tool to remove the blue cast in the snow and increase the colors in the water. I removed some spots with the Spot Healing Brush. I added a curves adjustment layer and cropped.
