I've just found this problem :

Byte size: ZERO | Content warning: NOT AN IMAGE

Can someone tell me what the purple haze is? Is it a bad sensor?

This is a 60sec exposure (CHDK) btw and the sensors temp. was about 33C.

Since you have not gotten any other replies, it seems this could be 'fringing'. You might do a broad Search on the main branch of this Forum, until someone can give better info related to the G specifically.

Update your firmware: http://usa.canon.com …ot_g10#DriversAndSoftware

Corrects the phenomenon concerning the PowerShot G10 in which a magenta (reddish purple) cast appears if RAW images are recorded under the following conditions:
1) Continuous shooting under ISO 1600 setting.
2) Single shooting only if the LCD monitor display mode is set to the OFF position.

Images that are affected cannot be confirmed when viewed on the camera's LCD monitor. It can only be confirmed when using image processing software to develop the RAW images on a PC.
