ThatвЂ™s why we recommend doing this process manually. Instead, your device does the HDR photo merge for you.Д«ut this auto function comes with a caveat: You canвЂ™t tweak it at all once it combines all the photos. If you use your cameraвЂ™s built-in HDR mode, you donвЂ™t need to process the images in Lightroom. It will use the details in every frame and composite them to create a properly exposed image. Then, you can use Lightroom to combine the files through a process called HDR photo merge. It is worth shooting in RAW for the easier post-processing.ДЄpart from the correct exposure, your camera also needs to capture several pictures that are equally under and overexposed. The first part of HDR involves you taking three to nine photos of a scene. If you donвЂ™t do the necessary steps with your camera, you canвЂ™t create an HDR in your Lightroom at all. High Dynamic Range doesnвЂ™t start with Lightroom. Using HDR allows you to properly expose your window as well as show whatвЂ™s inside your room. Now, meter for the window, and youвЂ™ll find that the interior will look dark. When you take a picture, itвЂ™s highly likely you will end up with an overexposed window. In situations where the scene is too contrasty, it can be impossible to capture both the shadows and the highlights in one frame.ДЄs an experiment, try photographing your room and include the window.ДЇirst, meter for the dark interior of the room.

ItвЂ™s a technique that allows you to improve your exposure by equalising the shadows and highlights of any particular image HDR is the acronym for High Dynamic Range.
