HDR was particularly popular among photographers some years ago. It’s especially true when compared to an image obtained by combining multiple exposures. Lifting the shadows more in the single exposure degrades the image further.Įven with the modest 5 EV dynamic range, a single exposure will have terrible image quality. What if you reduce the contrast and increase saturation? Will you get the same results as the edited shot? Let’s see a 100% crop of the two images: Single exposure 0 EV (top) Vvs HDR from -2 EV, 0 EV, and +2 EV exposures (bottom)Īs you can see, the HDR shot (bottom) is cleaner and more detailed. You could say you need to brighten the shadows in the single exposure. Not to mention the colors are more vibrant and saturated. But the HDR image presents a little less contrast. A single exposure 0 EV (top) vs -2 EV, 0 EV, and +2 EV exposures (bottom) Next, let’s create an HDR version by combining three exposures taken at -2 EV, 0 EV, and +2 EV.Īfter editing them with the same settings in Adobe Lightroom, let’s compare them in the image below. Let’s consider a single exposure and say it has a value of 0 EV. At least if you want some good image quality. You should be able to capture the whole 5 EV dynamic range, right? Modern sensors can cope with 12-stop dynamic ranges or more. Other cameras even have a dedicated HDR feature that lets you freely adjust settings. Your camera lets you capture three images in this manner. +3 and -3 are regular choices.įor three images, the values should be 0, +3, and -3. These images are plus or minus on the Exposure Value (EV) meter. You can take many images if the number is divisible by three (excluding your mid-range exposure). The second photos meters light for the highlights and the third for the shadows. The first one is to capture a mid-range exposure shot. In most cases, this process needs at least three images. When merged, the picture provides an overall correct exposure. The method involves taking many pictures and then stitching them together.Įach image captures the scene at different exposures. High Dynamic Range photography is the method of merging images to create a final photo.
