‘Photography’ means ‘writing with light’ and that’s what we do with the camera – write or (better) draw on the film or sensor with the light coming through the lens. There’s nothing to say the picture must be realistic or even representational, and these few don’t try to be.
Sitting on Picnic Bay beach on Magnetic Island on Sunday evening I liked the lights of Townsville across the bay. My camera told me it wanted a very long exposure to capture them – four or five seconds – so I thought I would make a virtue of necessity and move the camera around deliberately while the shutter was open. Two different gestures with the camera produced the first two images.
On the ferry approaching the brightly-lit docks a little later I did the same sort of thing with a rather shorter exposure to produce the third image above.
Is it art? Who cares?
Surely the better question is, “Do I like it?”
And each of us must answer for ourselves.
