No, I'm not saying make shit up. But I'm saying you don't have to make it snap-shotty if you don't want to either. I guess the best way is to explain it in a picture.
You might take the train/bus everyday. So if you want you don't have to just shoot
But rather something a little more 'staged' in a way.
(A friends photo (Steve Speranza), his work is awesome. Shoots a lot of self portraits that somewhat inspired this project)
