Friends, a photo contest that i like to enter has a category for pleasing blurs, so i camped by the water and watched this magnificent trumpeter swan stretch his wings.  He must have stretched 10 times in the hour that i sat there.  I started at shutter speed 1/640 then to 1/500, 1/400 and finally 1/100 to blur the wings but keep the bird head and body sharply focused, does this image work for you? til Tomorrow MJ
