Little by little, the Windows Phone platform is being fleshed out with a bigger and wider variety of apps. For you photography fans, Adobe Photoshop Express is now available for Windows Phone 8 and Windows Phone 8.1 devices as a free download. For casual edits, this means you no longer have to export your photos to your PC for Photoshop-style touchups and the like -- just use your Lumia device instead.
The basics are there, like cropping and being able to straighten, rotate, and flip photos. There's also a red-eye removal option. Beyond that, you can use the one-touch "Auto-Fix" tool in Photoshop Express to correct for brightness, exposure, and shadows.
Other free options include slider controls for exposure, contrast, clarity, vibrance, and more; one-touch filters (over 20 effects to choose from), and easy sharing to sites Facebook and Instagram.
Of course, there are in-app purchases too. You can add a Looks Pack and a Noise Reduction Pack for even more options.
