    Default HTC One (M8): What is the purpose of the dual cameras in the back?

    Does anyone know why there are 2 cameras in the back?
    I'm interested in knowing the purpose of them...is there a special mode that utilizes both of them?

    "“Duo” camera - two cameras on its back

    The all new HTC One will be the first phone to feature two cameras on its back. We have actually already seen smartphones with dual rear cameras, but their goal was 3D photography, while the cameras on HTC’s new big thing are said to contribute to improving traditional 2D photography rather than 3D.

    The actual process of taking a photograph on the new HTC One actually looks pretty much unchanged - you see a single image through the viewfinder and you tap on a button to capture a picture. The actual benefits of the dual camera become visible once you open a captured image, as you can apply “Duo effects” to the picture. We’d also guess that HTC has bundled in effects like post-capture focusing, a depth map and the possibility to erase objects from an image, but we are yet to see a confirmation about these features. The other changes in the actual shooting process should be in faster focusing and a more pronounced depth of field effect. We have also seen demonstrations showing how the two rear cameras can be used to achieve lossless zoom, but we don’t know whether the camera in the new HTC One will have this feature on board."

    The similar technology is used in Nintendo's 3DS. Wonder how it'll be implemented in smartphones

    Some of those mentioned features have already been implemented on single-camera phones, such as the latest S5. Perhaps a way to add more pixels to the equation since it may still be 4-5mps each sensor.

    More info on lossless zooming posted by JeffDenver in a Nexus 5 thread:
    Corephotonic Dual-Camera Puts Optical Zoom on Phones - Videos - Boston.com
    According to this design one lens would be a wide angle, and the other one a "zoom". Software would allow you to combine the images for the distances between them? No idea, but we'll find out I guess.

    Another possibility aside from everything they mention would be real-time HDR using separate exposures on the modules. Everything they said definitely makes sense, though. Seems like a lot of this is going to depend on how well HTC does the software, though, and that can make a huge difference.

    Maybe somebody will take a picture of Marty McFly on a hover board.
