Firmware info[]
The ver.req file method is used to gather firmware information about this camera model. However no data is actually written to the ver.req or vers.req files!!! The information appears directly on the LCD display. The ver.req or vers.req file must still exist at the memory card's root directory to obtain the data.

CHDK Specialties[]
This section describes special CHDK-related things...
- To load CHDK from the card, turn the camera on by pressing PLAYBACK and keeping it pressed down while accessing the menu to load the firmware update.
- Since this camera has no print button, FACE (the left upper button with the smiling face) is used as CHDK's <Alt> button.

Notes:
- Active zone only excludes the black bars, not the darker areas.
- I don't know whether the black levels are right (please check).
- It would be great if someone could provide a better color matrix.
