It has been interesting to go through quite a few photos. As for my own while my Canon D-slr's show the aperture used( as well as an assortment of compact/bridge cameras ) Five Nikon D-slr's from 1999 to near present, all show the maximum aperture of the lens being used instead.
The addition of ISO speeds is interesting to see what other people are setting on their cameras. For myself, it's also depentdent on the camera being used as well as the lighting conditions. Most of the time my cameras are set to AV/aperture priority, 1/3rd stop under exposure. as a starting point. ISO setting depends on the camera and/or lens being used, as well as the lighting conditions.
As for flash indoors--- camera on manual ISO 800. 1/60th at F4 is my starting point. Edited by: Paul Hilton at:16th July 2012 22:55
