Light Painting – Pixelmator Tutorial
I really like to use Pixelmator and these new features, especially the Polygonal Lasso Tool, it makes the process much easier. As I’ve been writing here, every time I use Pixelmator I get really impressed with how fast is it, using filters like Gaussian Blur and other blurs is much faster and pleasant than Photoshop.
