High Dynamic Range (HDR) photography is a popular technique that blends a series of photos taken at different exposures and combining them into one image that looks slightly out of this world, similar to a 3D scene taken from a video game. It’s an attempt to overcome the limited dynamic range of most camera sensors, developing a full range of tones that, at most, only real human eyeballs can detect. Ordinarily, HDR enthusiasts would use an expensive DSLR camera and process these photos on a separate system using expensive editing software. But equipped with a powerful mobile processor, multiple photos taken at different exposures and software post-processing can all be done on a single device as small as a smartphone.
