Leaf is here!
While we have been busy working on Pixo SE, we decided to release a little application called Leaf which does the opposite of Pixo. You open or import an image it is already in Sepia or Negative and what you have to is to add its original colour by “Painting” over it.
It is FREE and very easy to use. Give it a shot http://www.bendigodesign.net/leaf
