A series of shots of this sunset proved the value of a polarizer in adding sky contast to a scene that otherwise tended to "wash out" at the level of light involved. Alternatively, a neutral density filter (didn't have one) might have worked. Needs slight rotation.
(All my pictures seem to need about 1 or 1.5 degree CW rotation working off the viewfinder edges as plumb/level references...think my Uzi's CCD must be installed askew by this much. Very difficult to compensate for accurately, so I've given up trying.)
