High dynamic range (HDR) photography is a technique in which you take a series of images at different exposures and blend them together to create a single image that has a wider dynamic range than is possible in any individual exposure. This technique can be used to create both images that look very natural and images that look like vibrant pieces of pop art.

 

 

The Use Of Bracketed Images – Video

 

WHEN PEOPLE TALK about HDR photography, one of the first terms that usually pops up is “bracketed images”, and for good reason. To create an HDR image, you need to take a series of images that include not only a properly exposed image but also images that are darker and lighter than the proper exposure. This set of images is called a bracket, and the images usually range from underexposed to overexposed.

 

 

When you shoot a set of bracketed images you get to decide how much difference there is between each exposure and how many exposures to take. Most DSLR cameras have an automatic bracketing function that will change the exposure for you, but you can also do this manually or with the exposure compensation setting on your camera.

Tone Mapping Explained – Video

 

HDR means that a photo contains more dynamic range than the camera can capture. To create an HDR photo, you normally take two or three shots with different exposure levels and merge them. Tone mapping is the process of converting image tones from a higher range to a lower range.

 

 

HDR photography is aimed at overcoming the limitations of cameras that can’t capture the whole dynamic range. Tone mapping is aimed at properly reproducing the dynamic range on the standard display of a device, which is also limited in the colors it can reproduce.
