The developers of CyanogenMod announced the merging of HDR functionality into the CM 10.1 camera app yesterday, High Dynamic Range AKA HDR mode is a process that takes multiple images of a shot and then merges them together to produce a single photo. The technique is useful when a scene contains both bright and dark areas, though it can also be used effectively to add some "pop" to an image.

When someone snaps a photo with the function, a total of three pictures (one at minimal, neutral and maximum exposures) are taken and combined into a single HDR image with the help of an algorithm.

Differences in shutter speed, sensors and optics means quality will vary across smartphones, but the CyanogenMod team says that mid- to high-end devices outfitted with decent imaging hardware - especially those with zero shutter lag - should perform admirably. The CyanogenMod team also  recommends using a stand or tripod to thwart movement and vibration from fouling up photos.
