What can I do with the Lumia Refocus app on my phone?

Lumia Refocus is perfect for capturing close-up (macro) shots of static objects and scenes. You can also take close-up photos and get everything in focus (All-in-Focus feature), which is more or less impossible to do with a normal camera. You can also do color-pop on a single object/area. The rest of the image will be in black & white with a bit adjustment to the contrast levels to make it more 'artsy'.
