Record Sound Before and After Taking Pictures!
With the Optio W20, not only can you add a voice memo to a still picture,
but by switching to Synchro Sound Record mode, the surrounding
sounds are automatically captured until you press the shutter release
button to take the picture. A total of 20 seconds of sound, 10 seconds
before and 10 seconds after the shutter release button is pressed, are
saved. (p.74)
For recording yourself saying "Say cheese!" or "Look at
the camera"
For including the cheers of the crowd at exciting
moments of a sporting event.
Add Fun Frames to Your Pictures!
With the Optio W20, you can add a fun
frame when taking a picture of a child
or your pet, for example. (p.67) You
can also add frames to pictures you
have taken. Adjust the position of the
subject in the picture or reduce or
enlarge the picture size to match the
frame shape and size. Now you no
longer have to worry about the subject
not being aligned in the frame. (p.140)
For decorating your pictures
with a frame.
