For anyone with a Cannon Powershot camera you will be very interested in this:

This is a firmware add-on. It does not change anything on your camera. It loads from the SD card.
Some feature
– Record in RAW!!!
– Override shutter speed down to 1/25000 of a second /w flash sync.
– Override Aperture and Exposure times (up to 65 seconds)
– Record video up to an hour
– Motion detection accurate enough to take lightning photos.
– Auto Exposure Bracketing for HDR Photos
– Auto Focal Bracketing for Focus Stacking. (This is my favorite feature, I can take macro photos with everything in focus back to infinity. No more blurry backgrounds.)
-Flash Sync up to 1/64,000 of a second
– On screen histogram and zebra
Here are some example, keep in mind these are all with a normal point and shoot not a DSLR.
