CHDK has to be one of the most innovative improvements to any camera that has ever come along since
the beginning of photography. Started out by some people who only wanted RAW out of their raw-
crippled cameras, it has now grown into one of the most adaptable, flexible, and full-featured operating
systems of any cameras ever made. We are all extremely grateful for the work that everyone has put into
this arena of discovery, implementation, coding, sharing, camera testing, (especially with the unknown,
and possibly high risk), and those that provide all the information on the Wiki pages (and elsewhere in
the world). Those who have contributed to this great stride in the world of photography deserve a huge
vote of thanks.

Many thanks go to the original developers
