U Creative Filters
Fish-eye effect
Gives the effect of a fish-eye lens. The image will have a barrel-type
distortion.
Depending on the level of this filter effect, the area trimmed along
the periphery of the image changes. Also, since this filter effect will
magnify the image center, the apparent resolution at the center may
degrade depending on the number of recorded pixels. Set the filter
effect in step 4 while checking the resulting image.
Art bold effect
Makes the photo look like an oil painting and the subject look three-
dimensional. You can adjust the contrast and saturation. Note that
the sky, white walls, and similar subjects may not be rendered with a
smooth gradation and may look irregular or have significant noise.
Water painting effect
Makes the photo look like a watercolor painting with soft colors. You
can adjust the color density. Note that night scenes or dark scenes
may not be rendered with a smooth gradation and may look irregular
or have significant noise.
Toy camera effect
Gives a color cast typical of toy cameras and darkens the image's
four corners. By adjusting the color tone, you can change the color
cast.
Miniature effect
Creates a diorama effect. You can change where the image looks
sharp. In step 4, you can press the <B> button to change the
orientation (vertical/horizontal) of the white frame that shows where
you want the image to look sharp.
