VII. Great Underwater Pictures Made Easy
(cont’d)
Limit video clips to 60 seconds or less
It’s better to record many 1 minute clips than a few long videos. Shorter
clips are much easier to share and edit. Remember, a 30 second clip is
about 35MB – 10 times more than one 13 megapixel still image.
Correcting fisheye lens barrel distortion
The built-in fisheye lens allows you to get close to the subject and still
fit everything into the picture. Some pictures taken of straight objects,
like a tree or horizon, may appear bent.
There are many photo editing programs available that can correct
this barrel distortion effect. Here is a BEFORE and AFTER example
corrected with software called ShiftN, which is a free download.
