Definition of an HDR File

You may ask what HDR is. In fact, it is a technology that can help duplicate a broader range of brightness. Therefore, photographers and imaging professionals employ this technique known as high dynamic range or HDR. As a result, the image you obtain is brighter, more realistic, and contains more information in the shadows and highlights.

In the context of files, a picture file created or processed using HDR techniques is occasionally called an HDR file. When storing a wider range of brightness levels, these files perform better than conventional picture formats like JPEG or PNG.
