Apparently, folks who have been looking for the app via the Windows Phone Store search feature have always turned up empty handed. Thinking out of the box, some others have also made use of a direct link to the Nokia Camera app, and this has also yielded zero results as well.
Just a little bit of background information here – the Nokia Camera app does come with a slew of additional features as well as capabilities for the camera when it comes to supported devices, where for instance, Smart Sequence would be able to make it a whole lot easier to shoot an action shot, while one can also maximize the use of manual settings in order to customize an image in the best way possible, according to your preferences. Well, at least there is the beta version of the app that can be downloaded here.
