High dynamic range (HDR) is a familiar phrase in the world of photography. It refers to taking three photos consecutively, one overexposed, one normally exposed, and one underexposed. The three photos are then overlapped to create an HDR photo. Did you know that now monitors are also equipped with HDR? Different to HDR in photography, monitor HDR is a new specification. With the latest compression technologies, the brightness and tones of the screen are completely sampled to ensure that the light and dark details of an image are retained. Compared to conventional standard dynamic range (SDR), the colors and effects presented through HDR monitors are more natural and true-to-life. Post-editing on professional monitors with HDR functionality enables photographers to clearly view and edit images in greater detail and maximize the potential of RAW files, consequently perfecting their craft. However, it is worth noting that although computer monitors support HDR effects, some software, such as Adobe Photoshop and Lightroom, do not support similar editing environments currently. Therefore, the utility of HDR mode depends on the software being used.
