If you've ever worked with Adobe Photoshop, then you know what a powerful tool it can be. And for those who need Photoshop on the go, I recommend Photoshop Touch.
The Photoshop Touch app from Adobe is more advanced than the basic editing app Photoshop Express. But don't be intimidated.
The Photoshop Touch interface will have you performing amazing edits and creating fantastic effects in no time.
Designed specifically for tablets, Photoshop Touch is also fully integrated with social networking sites so you can share your creations and view comments from within the app. For ten bucks, it's a pretty powerful program. (The company's full program costs hundreds.)
If you're an advanced user and feel like an image could use more work in Photoshop CS5, send it to the Adobe Creative Cloud and open it up when you're back at the desktop.
It's a great way to stay creative on the go, without sacrificing your basic editing needs.
