The unique Duo Camera on the HTC One M8 utilizes two camera sensor/lens sets, in order to capture a more complete depth of field information about a scene, and use it for various post-shot effects.
You can tap to focus on the foreground in portraits, or the background for added emphasis, and the rest will get artistically blurred-out, for example. HTC also lets you lay various augmented reality and color effects over the foreground or background, and all of this can happen after you've taken the shot. The kicker is that the depth information is collected with every snap, so you don't have to wait for the phone to take multiple photos with different focus setting, like it works with other manufacturers. The Duo Camera makes record 0.3s autofocus time possible, so it all happens instantaneously.
We already made a thorough camera comparison with the HTC One M8, and demonstrated all the new modes and effects that the Duo Camera makes possible. After all is done and dusted, however, we are interested to hear what you personally think about the new dual-lens camera that only HTC offers on its flagship. Do you consider it a welcome and useful invention, that adds significant value to the smartphone camera realm, or is it more of a gimmick innovation for the sake of it, whose effects people won't use on a regular basis? Take your pick in the poll below, and sound off in the comments.
