Trying out HDR18 May 2012
High Dynamic Range (HDR) photos try to capture a higher contrast between the lightest and the darkest parts of a picture (see wikipedia). You would normally need a special camera for taking HDR pictures, but you can imitate the effect by taking multiple pictures (>=3) with different exposures. Typical consumer cameras have only very recently introduced automated procedures for taking pictures with different exposures. Hackers have retro-fitted this capability to much older compact cameras such as my Canon IXUS 100IS. Using the alternative firmware CHDK you can run a script that creates the necessary 3 exposures. (I’ve blogged about CHDK and how to install it before).
