I interpreted this one a little more creatively.

First things first, I used a video camera, not a still.

Second, I assumed a timer was anything that measured time, since it could be something that counts down (as it was likely intended here), but we also refer to things that simply time things, like stopwatches, as timers. I then set the timer for the recording function.

Don't worry, the camera was still pointed away from me. I ran into the frame, and the following picture emerged as I was browsing the recording.

I'm in midair because I slipped and fell. Serves me right for pseudo-cheating, I suppose.
