Dock behind house....late in evening with full overcast skys, temps in 40s and wind at about 15mph. Everything is gray except a blue tinge in clouds...so I turned on the image effect for VIVID and setup my tripod. This picture is the first I have ever manipulated. Made it B&W but then allowed the blue tint of the cloudy sky to show through at top. The only color except for dark and gray shadows. Made duplicate, opened layers, copied B&W over color and anchored. Then made sky transparent so color would show through. Image resize and unsharp mask slightly trying not to make any halo effects.
