High Dynamic Range Imaging, or HDRI, is a technique used in photography and imaging that captures a wider range of brightness levels than standard imaging methods. By combining multiple exposures of the same scene, HDRI allows for more detail in both the brightest and darkest areas, resulting in a more realistic and vibrant image. This technology is commonly used in various fields, including video games, cinematography, and digital photography. HDRI enhances visual experiences by providing richer colors and improved contrast, making images appear more lifelike and immersive.
