High dynamic range imaging

High Dynamic Range (HDR) imaging is a technique that helps to capture a larger range of brightness levels in a picture than what is normally possible with digital cameras. It works by taking multiple photos with different exposures (pictures taken with different levels of brightness) and combining them into one image. This makes sure that the final image has more details in both the light and dark areas. HDR can help produce more realistic-looking photos with more vibrant colors that look closer to what you actually see in the real world.
