I photograph. Some of it is just snapshots, some of it is quite good. Some of what is quite good is commissioned or sold so I cannot show it here ;-) The snapshots there are about 14000 of, filling 20 Gb on a dedicated web server.
I have a small hobby photographing man-made geographical markers. Buoys, lighthouses, aeronautical warnings on mountains and buildings. Maybe I will compile an anthology one day.
I have another small hobby photographing patterns - mainly wrought iron grates, grilles, balconies and gates in different countries. Should have enough material for a coffee table book soon :-)
