Are you not currently a Photoshop user? Adobe offers a Photoshop 30-day trial that you can download right now and it will provide you with plenty of time to learn how it works. If you don't want to eventually purchase Photoshop because it's too expensive, much of what we're going to discuss in these lessons will apply to not just to Photoshop but pretty much most of the standard photo-editing and design tools you'll find (Pixelmator is a great $30 alternative on the Mac, and GIMP is a free, open-source cross-platform option). We've chosen Photoshop because it's the most commonly used, but you're welcome to follow along using other software as well. Today's lesson is pretty Photoshop-specific, but as we move along you should be able to use other software to do most of what we discuss.
