You can set all these kind of effects with camera instance itself. Walk though the below code …

Camera camera = null;
camera = Camera.open();

if (camera != null) {
   try {
     Camera.Parameters parameters = camera.getParameters();

     // Set all kind of stuffs here..
     parameters.setSceneMode(Camera.Parameters.FLASH_MODE_AUTO);
     parameters.setColorEffect(Camera.Parameters.EFFECT_SEPIA);

     camera.setParameters(parameters);
     camera.setPreviewDisplay(surface_holder);
     camera.startPreview();

   } catch (IOException exception) {
     camera.release();  
     camera = null;  
    }
}
