![]() To deal with the dilemma of capturing photos in a high dynamic range, there are several techniques invented, one of which is to take multiple shots of the same scene, only change the exposure for each shot, and later merge them into a single photo.Īccording to the search result of HDR photography, when most articles talk about HDR photography, they are referring to this exposure bracketing technique. However, this is not the same as the HDR photography technique that involves exposure bracketing and merging. If the pictures are created the same way as described above, and you are viewing that image in an HDR device, then what you are seeing is an HDR photo. ![]() Similarly, when a game is mastered in a high dynamic range in the production, and your device support displaying it, then you are enjoying the HDR video game. Sometimes, it only means the device can play that HDR video (as opposed to not being able to decode the content and instead showing you a playback error message), but not in high dynamic range format, meaning you are still watching SDR, and not enjoying the wide gamut and higher brightness level in HDR content. There are TV or mobile phone manufacturers claiming their product support HDR video, and you need to make sure what does it mean in fact. For instance, in terms of display, the TVs or projectors must be HDR compatible, with a peak brightness that matches certain HDR standards, such as 1,000 nits as opposed to 100 nits of SDR display.Įven if the content delivered to you is an HDR video, yet your TV doesn't support HDR display, then what you are seeing is not a high dynamic range video. To be able to view HDR content, it entails that from capturing, production, to delivery and displaying device, each phase is dealing with true HDR content. So, for a high dynamic range, that ratio is higher than what we can see on traditional standard dynamic range (SDR) TVs or computer monitors. Now in terms of imaging (including the videos and images), dynamic range describes the ratio of luminance in the lightest area comparing to the darkest area, that is, if the contrast is high between the darkest shadows and that of the brightest highlights. ![]() The idea of dynamic range - note that we didn't capitalize the phrases - is to describe the ratio between the largest value and the smallest value contained in a changeable amount. Even inside the scope of photo and video, it can be referring to completely different ideas.īesides the complexity of the production, mastering, delivery and display process that involve high dynamic content or scenes, the marketing strategies of various brands that takes HDR as a hype also add ambiguity to it. Selecting a region changes the language and/or content on and high dynamic range are cover terms for many things depending on the specific context. After editing, you can convert your image into a TIFF, JPG (or JPEG), or other format as needed. These files contain greater tonal information and more accurate pixel values.
