You can easily change the colors in an image when it is shot both stills
and movies, allowing you to enjoy producing various effects.
Depending on the shooting conditions, however, the images may
appear rough, or you may not get the expected color. Before
photographing important subjects, we recommend taking trial shots
and checking the results. By setting the [Save Original] function
(p. 147) to [On] when shooting stills, you can also record both the
altered image and the original, unaltered image.
