Re: [android-developers] camera: can I create star, diffraction (etc.) filters?

Emulating a polarizing filter properly will be very difficult. One of

and color saturation. Polarizing filters are also used to reduce or
eliminate various reflections in a scene: light bouncing of leaves,
reflections in the water, etc.
