A technique used by HDR software to ‘map’ the extremely wide brightness range of a high dynamic range image into an editable form where the extremes of shadow and highlight detail are preserved. It’s usually the first and sometimes the only step in making an HDR image.
HDR (high dynamic range) images are usually created by blending a series of different exposures of the same scene to capture a wider brightness range than the camere could capture with a single exposure. These are then blended together by HDR software using a ‘merge’ process.
HDR stands for high dynamic range photography. It combines a series of frames taken at different exposures to capture a much wider dynamic (brightness) range than the camera could capture with a single exposure. These exposures are merged using HDR software.
When you merge a series of different exposures to create a single HDR image, you sometimes get movement between the frames from leaves blowign in the breeze, waves, pedestrians and moving vehicles, and these can cause ‘ghosting’ in the merged image. Most HDR software has a ‘ghost removal’ option which slows down the merging process […]
Taking a series of shots at different exposure settings in quick succession so that you can choose the best later or combine them in an HDR (high dynamic range) image. See also: Top 12 HDR tips
Mac-only HDR software developed in conjunction with HDR specialist Trey Ratcliff. It can work with single images or merge a series of bracketed exposures. You can apply one of many different preset effects or create your own with the manual controls.
