Smart HDR is a photography feature that enhances images by capturing multiple photos at different exposures. It combines these images to create a single photo with improved details in both bright and dark areas. This technology helps to produce more balanced and vibrant pictures, especially in challenging lighting conditions. The process involves advanced algorithms that analyze the scene and select the best elements from each exposure. Smart HDR is commonly found in modern smartphones, such as those made by Apple and Google, allowing users to take high-quality photos effortlessly, even in tricky lighting situations.
