CAMERA SETTINGS
Here are the camera settings you should check

In the standard Canon menus:

Switch to photo mode, and open the "Settings" menu, (by pressing FUNC/SET)
On the left you should have the following values

	Mode: 			Manual
	+/- (Exp.)		0
	White Balance		Day Light
	My colors		Off
	Metering		Evaluative
	Image quality		Fine
	Resolution		M1 (5M 2592x1944)

Switch to Video mode and again open the "Settings" menu, by pressing FUNC/SET
On the left you should have the following values
	Video			Standard
	White Balance		Day Light
	My colors		Off
	Resolution		640x480 30 fps LP

Switch back to Photo mode. In the "Setup" menu (the one you open with the MENU key) you should have the following values:

Camera (First menu, with the "camera" icon)
	AF			AIAF
	AF-Assist beam	Off
	Review		Off
	IS mode		Shoot Only

Setup (Second menu with the "tools" icon)
	Mute			Off
	LCD brightness	miminum
	Power saving
		Auto power Down	Off
		Display Off		3 min.
	Date/time		check that the time is correct (for logging)
	File numbering	auto reset
	Auto rotate		Off
	Lens retract		0 sec.
	Video sustem		???? I don't know, I must see what this setting actually does. for the moment, leave NTSC
Personalize (third menu, with little guy and camera)
	Nore really important, but I suggest ot have everything  Off apart
	Operation sound	1
	Shutter sound		1


	Theme			Off
	Startup image		Off
	
Close the menu.

Activate CHDK going in Alt mode (pressing the "print" button)

Open the main CHDK menu pressing the MENU key

Extra photo operations
	All values to their defaults, apart:
	ND filter state			Out (do not confuse it with "Off"!!)
	Clear override values on sta	Unchecked (do not confuse the men item with the "Clear on start" that you find under "Zoom Override"
					This is on of the last items in the menu

This will activate a red alert on the display "ND FILTER: OUT". It's ok, it must be there. It's an alert because now (because of the ND fiterl being out) if you shoot "normally" (i.e. without script) you might end up having badly over-exposed photos)

Raw parameters
	Save Raw			Unchecked

This is important: if we are in RAW mode the caera will be much slower and will eat much more batteries. 
Also, please note that there is a short-cut key that activates RAW mode. I sometimes have turned it without realizing and the camera would behave oddly.
You recognize the RAW mode because you have a small text in th display saying RAW:nnn and after shooting any photo the blue LED (inside the print button) turns on, and the camera says "BUSY" for a few seconds after each shot.
If you have these symptoms, disable RAW mode
