I used Magic Lantern v2.3 with a Canon EOS 500D mainly for white balance to allow colors look sunny on a rainy day.
Other features I like to use are the "Focus Peak" with manuell lenses and "LCD Remote Sensor" do I use on a tripod when photographing HDR.
Many thanks to the Magic Lantern Team that made such great piece of software!
