I do quite a lot of this. Some of my work appears on this site on a more or less daily basis, but I have other places where I show things off:
Flickr – I don’t do as much here as I used to, but there’s a lot of my older pictures there, and a small number of newer ones
500px – I need to do some pruning here. This is a place for your (and my) best work only. There’s a lot of great work on show by some great photographers. And I’m there too.
Les Bessant Photography – My latest venture. This is my customised site powered by SmugMug. You can actually buy my photographs there as prints or high-resolution downloads. Commercial licences are available, he said hopefully.
