I was experimenting last week with Adobe Camera Raw and found a pretty handy trick that allowed me to double process any image in Adobe Camera Raw. This is a pretty neat way to take your single exposure RAW files to the next level to really exploit that dynamic range. With this technique you can squeeze every ounce of dynamic range out of any RAW file but still maintain your original edits to the original RAW file by first saving it as a TIFF and re-opening it an Camera Raw.
