All pictures were taken with the smallest possible aperture to increase depth of field. The ISO was set as high as possible (800) without overexposing, and the shutter speed was automatic (between 1/34 and 1/1700 sec).
I appear to have knocked the aperture for the last 6 pictures - easily done on this camera. :-(
I will try to get another set in the early morning, just after dawn, but then the tourists will be taking their breakfast. And another set in the late afternoon. At twilight I can turn on the lights in the covered area.
Any suggestions on how best to tackle this difficult subject are most welcome.
