Very few images exploit the full range of possible brightness tones, from the lightest lights to the darkest darks. Often, you’ll have more info on one end of the histogram than the other, meaning that either the highlights or the shadows are well exposed and full of detail, but not both.
That’s because digital cameras have a limited dynamic range; they can collect only so much data in a single shot. If you have a scene with both light and dark areas, you have to choose which area to expose correctly. In other words, you can’t expose for both areas in the same photo. ^[Adobe Photoshop Lightroom Classic Classroom in a Book® (2023 release)#^1c95bd]
HDR images are composed of several similar images shot with just a difference in exposition.
