I recently installed CHDK on my Canon A495 Camera. When I access the alternate menu, I see something called Value Factor underneath some options.
For example: When I went to override the shutter speed, underneath that option there is one called "Value Factor" I can only set it to 1 or off. I am not sure what the function of that is. The same case applies to Overriding the ISO factor.
Please clarify what is this Value Factor? Should I put it to 1 or off?
Set it to
OFF to disable shutter speed override. Set it to
1 to enable shutter speed override.
In general in the <ALT> menus, value factor is like a multiplier. You multiply the value by the value factor. For example, take a look at the Override ISO value and value factor on the same menu. Set the overide to 64 and the value factor to 1 and get ISO 64. Set the overide to 64 and the value factor to 10 and get ISO 640.
Update : take a look at this short animated link
