Hello all this is from my walkabout today. This is from a tiny creek in Warren County PA Canon Digital Rebel 300D, 50mm prime lens @f22, 5 second exposure @iso 100, it was so shady and cloudy I did not even need to use a ND filter this time Shot in RAW mode, converted to 16 bit tiff with Rawshooter, converted from Color to B&W Photoshop CS2, levels and slight curves adjustment
