HDR photography reveals details lost in the shadows or highlights of a single shot by merging several images, all taken at different exposures together into a single image. If this is done wrong, the technique can easily lead to an image that looks over processed, however when done right, HDR is an excellent tool for revealing all the details in a high contrast scene. Dynamic range is a term used to refer to the difference between the darkest and lightest areas of an image. Some tips for landscape is the exposure settings that you choose have an effect on this, starting with aperture. To get the sharpest, clearest image possible, it’s best to shoot with an f-stop number that’s about two to three stops higher than the lowest possible (a mid-range aperture, like f/8 usually works well). Using an aperture too far toward either end of the spectrum, such as f/2.8 or f/22, can cause a subtle reduction in clarity. Also to have saturation.
