I've recently started writing some blog posts and figured I'd provide a link here for those that are interested. First up, I've released some Photoshop actions that have saved me a lot of time over the years. They're especially useful for game artists.
In addition, there's a post that provides a mini-tutorial on how to set-up Photoshop's alpha channel colour profile correctly. The default isn't the most ideal for game artists.
I plan to release some brushes and cover other topics over the coming weeks, months, years!
