THE Pro software is Photoshop in one of its many configurations- How deep is your pocket and deep do you want to go into the complexities? Photoshop will set you back 600/800 smackers and can be a head ache to run inless you are with it12/7
Possibly a batter bet is Paintshop Pro now in version 9 for 70/100 smackers.
Or cheaper yet but very versatile Roxio Photo Suite not in version 7 for about £40.
All have downloadable trial I believe or are available on Cover discs
Well Photoshop seems to be the industry standard but costs an arm and a leg. I have Photoshop 7 and Paint Shop Pro 7. I tend to use PSP as it is fairly easy to get to grips with but Photoshop has so much more to offer. As Completealias has said Photoshop is difficult to learn. I have a friend who is now an expert with Photoshop so I am learning from him. There have been many tutorials on Photoshop on cover disks, mainly Digital Camera magazines as opposed to PC magazines. I have tried a couple of the tutorials and the results have been very good. Still an awful lot to learn though and I couldn't do on my own, (that is, without the tutorial).
