Abstract

High Dynamic Range (HDR) technology in the field of technology has developed significantly in recent years and its importance has become on the digital moving image. Many photographic equipment has appeared with High Dynamic Range (HDR) technology available in cameras and cameras, and they have succeeded in designing and creating colors for the photographed view inside the camera patch or special programs. By correcting one color, the goal here is to achieve a better image, degree of clarity, and high contrast, which always highlights it in ninety, achieving always better results and more realistic images than before, in a way that is easier to match the human eye. The human eye is able to distinguish a wide spectrum of brightness contrast that camera lenses cannot do, so HDR technology tries to compensate by obtaining as much information as possible and displaying it in the image or scene depicted. The development added by ARRI ALEXA is the HDRx feature for cinema cameras, as this feature works on the ability to shoot in both high and low-light areas. With the development in the form of cinema lenses, the lenses became quick to respond to light and have high accuracy and contrast. Also, the developments in display screens made them display moving images with high dynamic range in 4K technology, as these developments helped in the overall success of the image and meeting the viewer’s requirements.
