These tutorials demonstrate some basic image editing techniques using Pixelmator, a modern image editor for the Mac. Pixelmator is similar to Photoshop and supports layers, blending, opacity and color correction but also features some wicked cool Quartz Composer filters and special effects that work in real-time using Core Image. The real-time filters are fast and powerful since they tap into your Macs graphics processor. You can download Pixelmator and give it a try.
