Adobe has released Photoshop Express 2.0, a new version of its universal image editing and sharing software for iOS. It’s a free download from the App Store.

[ad#Google Adsense 300×250 in story]Photoshop Express helps you edit your images, including cropping, straightening, rotation and flip. You can adjust color using exposure, saturation, and tint controls, change photos to black and white, and manipulate contrast, apply filters, special effects, and frame your photos with borders.

New to the 2.0 release is support for a $1.99 in-app purchase called the Adobe Camera Pack. The Camera Pack includes three new features – Reduce Noise, a self-timer, and “auto review,” which gives you a quick look at your photos as you’re taking them.

Other changes in the 2.0 release include a new Camera workflow; support for the “Retina Display” found on the iPhone and fourth-generation iPod touch; and multitasking support.
