A New Technology

Digital photography lends itself well to image processing methods unavailable with the old film, developer, and what not process of making pictures. One of the tricks digital does really well is jamming a wide scene brightness range into a single image. In black and white something called the "zone system" allowed one to extend the range of tones captured by film into an image printed on paper. Digital can do something trickier when a wide brightness range is bracketed and then smooshed together to make the final pic. Good articles about High Dynamic Range (HDR) all over the place. These are pix done in approximate fashion from camera-output jpeg.
