CyanogenMod just added HDR camera functionality for approx all devices

Yesterday. the CyanogenMod Team just added HDR camera functionality for approx. all devices running on CM10.1 Its HDR functions is similar to that available on the Nexus 4.

The CyanogenMod HDR mode can capture multiple pics, and then render them together to form one HDR image. 

The camera can take 3 images- first under exposed, second neutral exposed and third over exposed - and render all into one image.

Before using the new HDR functionality, you should know the following points :

1. Images are extremely sensitive to movement and vibration, you should use a tripod or stand whenever possible.
2. Action shots and moving subjects will most likely render poorly on lesser camera hardware, especially those with slow shutters.
3. As we are essentially averaging 3 images to form 1 image, the longer it takes your camera to capture all 3 images, the higher the chance for oddities in the rendered picture. 
4. When enabled, we delete the 3 'intermediate' pictures, you will only be left with the final composite.
