Photoshop has long been my photo-editing program of choice. Its downsides, though, are the price (really high) and its size (really big). But as of today, you can access its basic functions — adjusting the white balance, hue and saturation, etc. — via Photoshop Express. There’s also a really neat “pop” function that isolates a chosen color and makes everything else black and white.

A membership includes 2 GB of storage space, and best of all, it’s free!
