A while ago I read an interview with Ted Craig (an amazing photographer). He uses himself in a lot of his photos and ideas. They asked him why he did this, and he responded saying because he is always accessible.
The other day, I really felt like shooting- but it was cold, and I was feeling bored with shooting things in my apartment. I hate pictures of myself, and even hate posting pictures of myself even more. But I decided to try the old self portrait. I set up my camera on the tripod, and started. turns out I found one I actually liked of myself. It had the right feel (felt like me).
