Canon POWERSHOT SD750 DIGITAL ELPH User Manual page 62

You can shoot images with the original colors transformed. This can
be performed on movies as well as still images, allowing you to
enjoy photographing with image or movie effects.
However, depending on the shooting conditions, the images may
appear rough or you may not get the expected color. Before you try
to photograph important subjects, we highly recommend that you
shoot trial images and check the results.
If you set [Save Original] (p. 64) to [On] when shooting a still image,
you can record the original image as well the transformed one.
