We are just a few years away from celebrating the 200th anniversary of photography. The first permanent photographic
record was made by Niepce in 1826, the view from his window at Le Gras. After many development cycles, including
some periods of stagnation, photography is now experience an amazing period of growth. Change since the mid 90's
going into the next several years will completely modify photography and its industry. We propose that the digital
photography revolution can be divided into two phases. The first, from about 1994 to 2009, was primarily the
transformation of film-based equipment into their digital counterparts. Now, in the second phase, photography is starting
to change into something completely different, with forces like social networks, cell phone cameras and computational
photography changing the business, the methods and the use of photographs.
Computer based color imaging is rapidly moving from the realm of the specialist to the general public. To enable users the greatest benefit from advances in color image reproduction technology, the computer systems have to modify to incorporate this new technology. Two possible approaches are described - by the adoption of color management system software, and by the adoption of device independent color variables. Although both systems are likely to perform equally well when properly configured, the later is likely to be the long term choice as it will yield the most robust, lower cost and transparent system.

An accurate and inexpensive method for calibrating computer displays is introduced. The characterization is done entirely by visual comparisons and the results are equivalent to characterizations made by commercially available instruments. The method is based on a parametric CRT model, requiring that the user perform only a limited number of comparisons.
