Our old mate Steve Caplin is at it again with a new video course on Youtube. This one is called "2 Minute Photoshop" and aims to eventually be a comprehensive Photoshop guide in 2 minute increments. Give it a look, you know if Steve's involved it must be worthwhile. Make sure you subscribe and share on your social networks to give him a good start.
