What does HDR mean and how to use it + 5 free HDR apps

HDR is a special technique that makes photos look considerably better when used in an appropriate way. Nowadays it is widely introduced to phone cameras in iPhone and Android devices and can also be used while shooting pictures with the help of different HDR apps.
Meaning
The abbreviation HDR stands for High Dynamic Range. Dynamic Range is the ratio between the darkest and the lightest values of an image.
The filter can, so to say, “play” with lights in order to get the best possible photo. For example, if you are shooting a picture in a room with a lack of light or, on the contrary, with too much light, HDR will moderate all the excess.
The technique is based on merging together several shots and highlighting the best in each of them. As a result, pictures become more vivid and look more natural – closer to how a scene is seen by a human eye rather than by a camera lens.
Due to its peculiarities, HDR shouldn’t be applied in situations, when something would potentially be moving, portraits in sunlight or pictures with high-contrast scenes. It would rather make them look worse than better.
However, landscapes and scenes with heavy shadows or bright lights would become just gorgeous if shot with the help of this technique. Fortunately, HDR apps work in such a way that the camera produces two photos – the one with HDR and the one without it.
Well, now you know exactly what does HDR means. Below you can see some effective apps which are designed to create stunning pictures with the use of HDR.
