App allows for focal point to change after photograph has been taken
Nokia is rolling out its Lytro-style Refocus app to other devices in the Lumia range with high-resolution cameras. The PureView-equipped Lumia 1020, Lumia 920, Lumia 925, and Lumia 928 now join the Lumia 1520 in being able to change the point of focus in a photograph after it has been taken rather than before, with the app now appearing in the Windows Phone Store.
Based on Scalado technology, the Nokia Refocus app takes multiple shots at a time instead of just one, a process that Nokia Conversations states takes a few seconds to accomplish. Between two and eight images, each with a resolution of five megapixels, will be taken by the app, with each having a different focus setting. After some processing, the resulting file allows the viewer to select a specific point in the photograph, with the image altering to match.
An additional "Color Pop" option lets the user select the area where they wish to remain in color, with the rest of the unfocused image going to black and white, and also automatically tweaking the contrast. It is also possible to set everything in an image as in-focus, rather than a single point.
Created Refocus images are stored in SkyDrive, and have their own unique Refocus webpage issued to it for sharing with others.
