The (zoom) ins and outs of low light zooming on your smartphone
(All About Windows Phone)

You`d think things would be simple, wouldn`t you? Shoot a photo in low light, select the 2x or 3x (or whatever) telephoto camera in your phone and snap. You`d think that you`ve just shot a low light photo with the physical telephoto camera in your phone, but that`s not always the case... Even with the latest multi-frame techniques, phone camera software can still take the executive decision to forget a telephoto lens altogether and provide a digitally zoomed shot from the main lens if it thinks results will be better. Some thoughts and tests below, though don`t worry too much - with smartphones from the last few years, light has to get really low before the extra lens is taken away from your imaging armoury.
