Video and Still Cameras Converge Michael Reichmann has written just last week a timely and amazingly consise yet complete essay :
"Understanding Video:
A Video Primer for Photographers" at The Luminous Landscape.
"The world of image recording seems to consist of two isolated realities – video and still photography. Though they are similar in many ways they are worlds apart in others. But these seemingly irreconcilable worlds are converging, and I have already written on these pages about this convergence. Nikon's announcement of the D90 in late August – the world's first DSLR with video capability – just confirms that the worlds of still photography and video are on an inevitable collision course – at least insofar as equipment goes."
