The latest instalment of Photoshop's younger and less-loved cousin, Lightroom, is up for grabs from Adobe's website. It's £100 to buy outright, or £60ish if you've got a previous version of Lightroom.
A photo organiser rather than editor, Lightroom still has some pretty sweet photo-retouching capabilities, especially if you want to do something like fix the exposure for an entire photoshoot. Lightroom 5 offers a new Advanced Healing Brush, letting you change the size of the brush to get rid of objects from your photos. There's also an auto-straightening tool, and most interestingly, a Smart Previews function that lets you work on a low-res copy of an image (to save space on your fancy-schmancy SSD), and then apply the changes to full-res images later.
