Under certain circumstances: very.
The first challenge of Dogwood2016 was a self-portrait, using the camera’s self-timer. Well, finding out how to do that was easy (I read the manual).
But the rest…!
If there’s anything I hate more than being seen with a camera in my hand, it’s being in front of the camera. I was only sure of one thing: the resulting self-portrait should not really show much of me. If you say that can’t be a self-portrait, yes, it can.
