By all means copy, use, edit any photos you think are worth it - just add a credit/link back to my flickr page please!

My favourite techniques are panoramas (stitched with hugin on opensuse linux), and hdr - or at least combining different exposures from the same RAW original in order to get good sky as well as shadow detail.

Of course, to do this, I use the GIMP (more open source magic ;-) ).

Most of my pics are simply opportunistic snaps whilst out with the dog!
