Gotta say that after using almost every version of PaintShop Pro from Jasc through 7 to Corel versions 8 to 11+ for complete photo editing, it is good stuff. It is less expensive than Photoshop and worth the savings. I dabbled with Photoshop and found at least one thing I liked better in PaintShop Pro. I suppose that if I worked through the learning curve, I would probably get comfortable with Photoshop, but I haven't found it necessary. Adobe Photoshop is more robust in features and in add-ons, but PaintShop Pro definitely won't leave you short on basics.
Every one of the images in my gallery have come through PaintShop Pro. Check it out if you are interested.
