Windows Phone Store offers an update to Adobe Photoshop Express
For a limited time, you can access features that normally would require an in-app purchase for free by using your Adobe ID (which also is free). This will give you the capability to use Reduce Noise, Defog, and Premium Looks. All of these features normally require you to dig deep into your wallet.
The freemium app allows you to crop, straighten, rotate, and flip your photos. And like drops, it removes the red from your eyes. You can also adjust the brightness on your pictures and shadows by clicking on one button. And a slider allows you to fix the exposure, contrast and clarity to your liking.
If you take a lot of pictures with your Windows Phone 8.1 powered handset, why not give this app a shot. It costs you nothing to download and install it on your phone.
