A Silicon Valley startup company called Lytro is working on a new digital camera that would let you adjust the focus of an image AFTER you've shot the image. AFTER! *socks blown off*
This would be very exciting for amateur photographers but I wonder if professionals would shake their heads at this new technology. Technology all too often has the unfortunate effect (affect? damn, I can never tell which one) of watering down time-honored skills, techniques, and traditions. However, one comforting fact is that technology, for now, is still wheeled by a person so application of technology is still but a tool that is subject to the creativity and inspiration of the artist.
