The cut down more user friendly version of photoshop would be a better start (WTF is it called…eludes me). There are so many features in the pro version that you will never use (believe me, I have been using it for 5 years and about 80% of the proggie is still semi mystery).
There is nothing you cannot do with it and it is a bit like poker, a few mins to learn and a lifetime to master.
