I'm male and I've never been great at having other people take my picture: it's not that I dislike it
per se, more that I always seem unable to pose well. However, I do end up doing self-portraits sometimes because they are a good way to 'say something'. My personal favourite is a slightly unconventional one:
Dead Link Removed
Yes, obviously the shadow is me, but it's a self-portrait in more ways than that. I used to be an archaeologist and the sign says "Museum"; the table and chair could relate to my love of food; the brick pattern of the floor is very similar to that of the courtyards in my old college; the bicycle represents another part of my life; the piano (you can see the grand piano, right?

) reflects the big part that music plays in my life; and of course, it is a photograph of a photographer taking a photograph. Finally, it is also very typical of my photographic style, which is surely a fundamental part of what makes me 'me'.
Portraits are supposed to reveal more about a person than just what they look like, which is why I always feel rather satisfied by this one: people who know me recognise me in it immediately.
A photographer not mentioned in this thread yet whose self-portraits I like very much is Sam Taylor Wood. I recommend anyone who doesn't know her work having a look.

PS that picture is online because it's in a competition being run by Channel 4 - you can find the galleries at
Dead Link Removed (all votes gratefully recieved!) There's some pictures worth seeing there: some good, some less so, and some unbelievably pretentious...
