Instant Images

In the days before digital photography, photographers in the field would normally sned their photographs to their agency, newspaper or studio via messenger. For most purposes, image-related information was limited by the speed of air travel. (And even earlier, by train or steamship.)

But digital photography has ushered in an era of nearly instant image transfer. With a digital camera and access to a computer with a mobile phone card, WiFi or other Internet connection, a photographer can transfer photos almost anywhere - even while an event is still in progress.

And this access hasn't just affected digital pros. Now almost anyone can contribute to the digital information revolution. Many newspapers and television stations, for example, actively invite readers and viewers to submit digital photos and video of breaking news events - essentially turning anyone into a professional digital photographer.
