Underwater-Photoshop :: Photoshop :: Filters
The traditional photographic filter is placed in front of the camera lens in order
to create an effect. You can still do this of course, however, for underwater photographers
this is less of an option if you have a housed camera because the filter is stuck
on your lens for the entire dive.
Digital filters are a much more convenient way to achieve the same results. This
is a fantastic step forward for the underwater photographer, especially when the
effects of filters underwater very with depth, whereas digital filters can be adjusted
in strength effortlessly.
It has to be said, for the underwater photographer; by and large effects filters
do not work. In a visual sense, we expect to see in a natural environment. There
are some exceptions to this rule and here are a few examples.
You can apply any digital filter to all of the pixels in your image, however, this
is not the ‘smart way’ to do it. You should always apply a filter non-destructively
rather than lose the original pixels forever. To do this you use smart filters.
This feature is only available in CS3 and later (and is another good reason for
upgrading if you have an older version of Photoshop).
