With Aperture-priority AE, the Optio 555 lets you take control over depth
of field. Select a large aperture to throw a background out of focus, or stop
down to a small aperture for clarity that extends to the horizon. Indeed whichever
aperture you choose, the Optio 555 automatically selects the most appropriate
shutter speed for pleasing exposure.
- Shutter-priority AE
Shutter-priority AE lets you select shutter speeds better suited to your subjects.
Freeze a fast-moving object through selection of a fast shutter, or choose
a slow shutter to create blurred effects that emphasize movement, for example.

or reducing the level of quality to allow further shooting. Once youve
resized the data, you even have the choice of whether to save it as a new file
or use it to overwrite the original image.
Excellent composition doesnt have to be confined to the time of shooting.
Indeed with the convenient Trimming function, images can be cropped at any time
and selected parts can be stored as individual new files.
The detailed histogram function is extremely handy during both playback
and shooting, allowing you to check the range of light levels with greater accuracy.
