No time ?
No time time to take a picture ?? True ??? Just in a hurry ? Entering the plane and the cabin crew is now watching you ?? So what. Take you P+S cam and do it. Catch the moment, document your steps for one day. This is an amazing thing. Try it.
Olympus E-P1, Lumix 20 mm, f1.7, shot from the hip. So what are you waiting for ?
