m860 camera stuck in sepia mode!

[eto]

For some reason my Huawei m860 camera is now taking pictures with a sepia filter (light reddish-brown coloring). I don't remember shifting or enabling a sepia filter nor can I find anywhere in camera settings (or general settings) an option to enable(OR DISABLE) a "SEPIA" filter!

How do I revert to normal camera, see the two pics attached!

I'm using android version 2.2.2

thanks eto
