What does Mobile Camera HDR mean? What scenarios are mobile HDR applicable to
4hw.com.cn: now all cameras on smart phones have HDR. When you take pictures with your mobile phone, you can choose HDR mode. So what is mobile HDR? What's the use of this function? Let's have a look.
The full name of HDR is high dynamic range, which translates into Chinese as high dynamic range image. The name seems very complicated, but in fact, to put it bluntly, it means that after the mobile phone turns on HDR, the camera will take three photos in succession, corresponding to underexposure, normal exposure and overexposure respectively, and then synthesize the three pictures, and synthesize the better parts of the three pictures, so as to form a better picture.
After finishing the principle of HDR, let's talk about why we should turn on HDR to take pictures. Just mentioned, HDR technology is to obtain a more balanced exposure effect by taking multiple photos and software synthesis. The advantage of this is that when there is a large difference between light and shade in the place where you take photos, HDR can keep the highlights and shadows of your photos in a relatively clear state, so as to create a feeling that the highlights are not exposed and the dark tones are not exposed. Make the bright part of the photo bright, and try to keep more details in the dark part.
Since HDR is so good, does it mean that you have no brain to take pictures in the future? Just open HDR to take pictures? No, the use of HDR is also divided into scenes. If it is used indiscriminately in inappropriate scenes, the effect will only be counterproductive. Let's briefly talk about the applicable and inapplicable scenarios of HDR.
1、 Applicable scenario
1. Low light scene
Go out to play at night and see some interesting scenes or want to take photos together, but at night, many places are lack of light, that is, what we call weak light environment. In this case, HDR can also have good results.
2. Scenery
When taking landscape photos, we often pursue the overall look and feel of the photos. However, the reality is that the contrast between the background and the shooting subject often gives us a headache. At this time, HDR can be used to alleviate this embarrassment. After using HDR, the overall appearance of the picture can be better and more harmonious without too obvious contrast.
3. Backlight portrait
Sometimes when you take pictures outside, you will inevitably encounter good weather and strong sunshine. At this time, I want my friends to take pictures of me. Is it really black? Why not use HDR to eliminate the disharmony?
2、 Not applicable scenario
1. Color rich scene
If the thing or scene you shoot is to highlight its rich color characteristics, don't use HDR, otherwise the effect will be worse.
2. High contrast scene
Some photos are characterized by highlighting differences and strong contrast. In this case, it is best not to use HDR, otherwise the contrast effect will be weakened.
3. Moving object
As mentioned earlier, the principle of HDR is multi photo synthesis. Therefore, if you use HDR to shoot moving objects, it is likely to cause photo blur.
Having said so much, I believe you have a certain understanding of mobile phone HDR mode photography. Make good use of HDR and make your mobile phone feel like a 'blockbuster'.
