If you don't have Photoshop, or are contemplating an upgrade, the best path to take is a fully functional trial version. If you're not sure if Photoshop, Photoshop Elements or even Photoshop Lightroom is going to serve your purpose, or you want to compare and balance out which variation best suits your specific needs, or even if you just want to play around and figure out if image editing is for you - my top tip would be to download a trial version. In this article I'll show you how it's done, completely legally and with Adobe's blessings.
