HDR Video Production Process Based on Optical Principle

HDR (High-Dynamic Range) is a digital image production method, which uses existing image recording and output equipment to produce digital videos composed of images with higher dynamic range. In the field of picture photography, it is common to make HDR photos by "exposure bracketing -- tone mapping", while in the field of video, this attempt is still at the beginning. In this paper, the basic problems of digital image production are explained by comparing the quality of different light-sensitive materials, and the necessity and feasibility of applying HDR technology to video production are discussed. Through the experimental method to study the structure principles of the video equipment used to shoot the HDR video, establish the referential flow of HDR video post-processing, and verify the feasibility of applying the HDR technology to video production.
