The following is an image captured near the time of maximum eclipse in Fresno, California at 6:34:00 pm.
The image is orientated with up corresponding to the local zenith. As one follows the Sun along the local azimuth the vertical changes.
The image above is one of the better images in terms of detail. The breeze tended to cause the telescope to rock back and forth which made capturing an image difficult. It was taken at 5:39:06 pm.
Supplemental (May 21): Google does not appear to be uploading EXIF image info any more. MS Office Picture Manager indicates two times for an image, a "Modified" time in "Picture properties" and a "Date Taken" in "Camera properties". The "Modified" time was 1 second earlier and is probably the one that agrees with the time shown on the NIST widget.
