Are their any apps to get some new camera effects for my phone?

Like a Negative style effect

By default, the camera application has 3 color effects : normal, b&white and sephia under options menu of the application itself.

Black and white is the effect that you want I think.

Regards.

Negative and B&W are two totally different things...

I am not sure if there is an app out there for this but check the app store.

Ill go have a look. yeah its not B&W I want a negative effect. they are real cool.

A warp effect would be good too? any ideas?

other then searching for apps non.
