was looking into
methods to create a torn paper edge effect and discovered a tutorial
on how to create them using Adobe PhotoShop. "No worries" I thought,
"I'll just recreate the steps using PhotoPaint". Alas, the tutorial
I followed primarily used channel manipulations - many of the steps
simply could not be repeated, or even modified for use in PhotoPaint
as the two different applications use channels quite differently.
Also, that tutorial used several filters (such as the Maximize filter)
which were not available in PhotoPaint.
The original PhotoShop
tutorial I am referring to can be located on the Web at http://navworks.i-us.com/freetut/rip.htm
. I would also like to add at this stage that I believe that the
method used by Navworks is overly complicated, especially in retrospect.
The method I will
demonstrate here is remarkably simple, and with a lot less steps.
Thus, after my initial
disappointment at not being able to directly recreate torn edges
using the PhotoShop-type method, I began investigating an entirely
different approach which turned out to be much simpler and more
flexible. The original method created a channel which was then manipulated
to create the final objects. Using PhotoPaint I found that it was
much better to create a black and white object, manipulate this,
and then create the final masks/channels to apply to various fills.
