Record Sound Before and After Taking Pictures!
With the OptioWP, 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. (1p.71)
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.
Choose a Frame Before Taking the Picture!
The OptioWP lets you choose a
frame and display it on the screen
before you take the picture, so you
can be sure that the frame
complements your subject perfectly.
(1p.72) Of course, you can still use
the editing functions to add a frame
afterwards. (1p.130)
For decorating your pictures
with a frame.
