It’s not Lytro-like light-field camera, but it’s as close as it gets, on your regular smartphone, given it is powered by Windows Phone, and it’s a Lumia made by Nokia. The Refocus app from Nokia is now available and it allows you to basically snap a picture now, without worrying about focus, and focus on objects later, again and again.
In order to get the best results, you should aim to capture “scenes with a great contrast in the depth of field, like macro shots”. The way this works is simple: Nokia Refocus captures two-to-eight independent images of the scene, each at five megapixels, while setting the focus on different objects; then it’s all “be aligned and forged together to make one image”. In addition to playing with the focus you can have a lot of fun and explore your creativity with the Color Pop feature.
You can share your images via SkyDrive, SMS, or Facebook.
