Yes , Brian - got that one badly off - had been taking a shot of a broken window - and used f4 for narrow DOF - did not work out anyway - and forgot to reset f stop
Looks well composed Jim but I cannot correlate the exposure with ISO 800 as I would relate that to "should have been" ISO 400, so can only assume the in-camera metering was fooled by the overall lighter areas (shadows tend to support this as somewhat devoid of detail). Why, in any case, did you opt for 1/8000 @ f4 for a static subject instead of, say, 1/500 @ f16 to get better overall sharpness? I would of course add the "correct" exposure should have been nearer 1/500 @ f11 to get better shadow detail. Hope that helps for future shots of similar nature as otherwise it's well seen and selected.
