Please e-mail to me, firstname.lastname@example.org, before Tuesday Midnight, 8 November, one or two jpg files, with your preference indicated. They should be sized to make good use of our screen (1920x1080 pixels); send full size if in doubt. Extras are welcome, but will be shown only if time permits.
If you don't have access to a scanner, or just can't get into scanning, consider sending me some ordinary photos of a flat subject, that is, something found or arranged on a plane surface, seen from straight on (not at an angle). The result will look very much like a scan. See Simon's recent post 'Leaf Galaxy', for example.
