Because this is what you end up with -- 10 seconds of two people desperately trying to maintain a smile, followed by the line, delivered ventriloquist-style… "Has he done it yet?"My mum is the master of trying to take a photo when the camera is set to video mode. Seriously, she has more videos of people waiting for her to take a photo than she does actual, you know, photos.I'd like to think she was doing it on purpose -- that by filming the taking of the photograph, she's deliberately capturing her subjects before they've had a chance to pose and preen, and that, as a consequence, she's documenting the true essence of people in a way that a studied still photograph never could.But she isn't, she's just crap with digital cameras.¬© JONATHAN BROWN
