Photos High Dynamic Range
What does HDR* mean ?
The acronym HDR is the abbreviation of the expression High Dynamic Range or "extended dynamic range" in French.
The dynamic range of a photograph is the distance between the darkest and brightest areas of an image.
The human eye has a very large dynamic range that allows it to discern infinite shades between light and dark areas of a scene or landscape.
But the sensors in our digital cameras are not as good. This is why the rendering of some scenes on screen or on paper can be disappointing.
Under certain conditions, when a scene is very contrasted, it is even impossible to get a well exposed photo.This is the case for example if you photograph a room with a window in the background or a person in front of a sunset.
HDR photo is a technique that can solve this type of problem and bypass the limits of the sensor of your camera.
