Last night I went to the Broadmoor Hotel in Colorado Springs with my photography group. The fresh dusting of snow made for some great photos. This is an 8-second exposure at f16 and ISO 400. The small aperture creates the star effect with the lights.
I made basic adjustments, made lens corrections and reduced noise in Adobe Camera Raw. In Photoshop I applied black & white and curves adjustment layers and used the Spot Healing Brush and Clone Stamp to remove some light refraction in the sky.
