    Sometimes it happens that the scenery looks great, but in the image turns out completely different. Perhaps the sun is too bright, or the object is too dark. It is for such cases that HDR technology exists. Information port Howtogek.com speak All you need to know about her.

    What is HDR and why it is necessary in photos

    HDR gives what photos

    Deciphers HDR in English is in the form of high dynamic range. In fact, this function allows the camera to increase the details of the brightest and darkest parts of the scene. The idea is that it helps convey the picture as the photographer see it.

    Imagine that you are taking a picture of a friend standing in front of a bright window. If you only take a picture, one of you will happen: either a person in the front will become a shadow, or the camera focuses on his face and spread a bright background. The problem is the limit of mobile chambers: they cannot simultaneously grasp a series of colors of different brightness, unlike human vision.

    HDR ignores this limitation with the help of cunning – taking some photos quickly with different durability. It is emphasized the bright elements, the other is dark, and the third is a bit. After that, the HDR algorithm combines three photos into one, selecting the best paragraphs of each picture. The result is an image with a balanced light.

    In any situation, HDR help

    • The sky is bright, a dark background. For example, in the park before sunset: The sky shines, but sunset on Earth.
    • The objects are illuminated from the back. An effort to take pictures of something or someone in front of a bright window and under sunlight often leads to a shadow.
    • Scenes with mixed light. Such as the interior with natural sunlight, or the image of the night roads with uneven light.
    • A detailed environment. Types of complex cities, forests, architecture – HDR help conserve the structure of objects will be lost in conventional photography.

    In any situation, HDR does not help

    • Object in motion. HDR combines some images at the same time, so the movement leads to blur and other artifacts.
    • Light light. With the lack of light, HDR only makes the image more noisy, or too highlighting the areas still dark.
    • Quick and unique moments. HDR is not suitable for taking scenes – dancing, laughter, blowing candles of the name of the crime. Image processing takes enough time to miss the moment.
