HDR (High Dynamic Range) is a popular branch of photography gaining acceptance over the last few
years particularly. CHDK has made this much easier for the low end because of RAW capture (HDR from
a single RAW), and bracketing (Multiple shots with stepped Tv, etc).
There are now many applications that are capable of HDR processing, including Photoshop .

Recently (Late 2010), Canon has produced the G12, and S95 Powershot cameras with HDR processing
in camera, which is done by producing 3 bracketed shots of a scene at different exposures, then
combining them in camera to create one HDR image, does this sound familiar ? ... And in 2011 the
SX40HS has exposure and focus bracketing, and NightScapes mode to combine several images to reduce
digital noise at high ISO.
