Attentive Huawei phone P50 users may have found that there is no HDR option in more camera modes. Why the current P50 canceled the HDR option, according to Huawei photography engineers explained, said that the P50 in the normal camera mode scene, the HDR function has been able to automatically take effect, that is to say, now every time you take a photo, even if it is a scene with a large light ratio, do not open the HDR function, you can do highlights but not exposed, the shadow has details, so the HDR option is canceled. The reason why there was this option before was that I was worried that HDR optimization was not good, so I made an option separately, and now after continuous optimization, I have been very confident that I can accurately expose each photo without opening the HDR function, so I canceled this function option.
So, what is HDR? HDR is an abbreviation for High Dynamic Range in English, which is a digital camera post-processing technology that can compensate for the lack of photo tolerance and is suitable for shooting scenes with large light ratios. Dynamic range refers to the camera photosensitive device to receive the relative ratio of the highest and lowest value of the photoelectric signal, reflected in the photo is the highlight and dark areas can show the details, the larger the dynamic range, the richer the level.
In the era of film photography, people could add dodge or burn by partially blocking the light when developing photos in the darkroom, so that the highlights and shadows were layered and details were preserved. In the age of digital cameras, two tools, Doge and Burn, can be found in Photoshop to simulate the effect of adding or subtracting light locally in the darkroom.
In order to get the picture effect of HDR, it is not enough to take a photo alone, you need to take a series of photos with different exposure values, namely high exposure, normal exposure and low exposure, and combine them into a photo with a perfect exposure effect of high dynamic range through the software.
Sony as early as the NEX-5 digital micro single camera has been equipped with HDR function, now some SLR cameras also have this function, after selecting the HDR function, even in the case of large light ratio shooting, regardless of highlights, dark bits can get a better level than ordinary photos, without the need to take multiple photos with different exposure values after the synthesis on the computer.
Today's high-end smartphones have HDR functions: most Android phones are hidden in the [More] interface, Apple phones open the camera's camera page, there is an HDR logo at the top, you can choose to auto/open/close. The technical principle is that after clicking on the shutter, the camera takes three pictures with different shades of light and shade in a row, and then combines them into a perfect photo, which can improve the details of the highlights and shadows of the photo, so that your photos look very clear, the picture is very uniform, and it will not be overexposed or too dark.
Huawei P50 Pro is equipped with powerful imaging hardware, but also has a number of groundbreaking digital imaging technologies. Huawei's latest imaging technologies, including XD Fusion Pro primary color engine, XD Optics computing optics, and XD Fusion Pro Super Filter System, can effectively improve the imaging quality of mobile phones when shooting. Among them, XD Fusion Pro ultra-dynamic range technology can increase the dynamic range capture capacity by 28%, record more light and shadow details, so that each photo, whether in low light or bright environment or in the case of large contrast between light and dark, can bring clarity, rich detail and can restore the imaging quality seen by the naked eye, so there is no need to set up a separate HDR function option.
