What is HDR? What does HDR mean in mobile phones?
Nowadays, people have higher and higher requirements for the camera function of smart phones. Now most mobile phones support HDR camera mode, so what does HDR camera of mobile phones mean? In fact, HDR is a technology commonly used in photography. Under HDR photography, photos can better show the details of bright parts and dark parts. How to turn on the HDR photography function of mobile phones? When is it suitable to use HDR? Here's a brief introduction.

HDR photography of mobile phones is a high dynamic range, which is used when the difference between the brightest and darkest parts of the object is particularly large. When HDR is turned on, there will be three photos of continuous shooting, corresponding to underexposure, normal exposure and overexposure respectively. Then, these three photos will be combined and the best part of each photo will be highlighted to generate an exquisite photo.

1, turn on the camera of the mobile phone. Here, we see that the HDR function is turned off. Click HDR.

2. Then, click "Open" to open the HDR function.

3. When HDR is turned on, the lens will return to the real yellow font HDR. At this time, click the lens and a box will appear, and the camera will automatically focus and fill the light.

What does it mean to take HDR photos of mobile phones? When is HDR suitable?

1, landscape photos

In large-scale landscape photos, there is usually a huge contrast between the sky and the land, so it is difficult to deal with this contrast if your camera only takes one photo. With HDR, you can capture the details of the sky without making the land look too dark. Conversely, you can capture the details of the land without making the sky look too bright.

HDR ensures the color of the lake and the sky, and also ensures the exposure of the forest.

Use HDR to make the overall exposure and color level of photos better.

2. People in the sun

As we all know, light is very important for a good photo. Too much light on the face (such as dazzling sunlight) will cause shadows, glare and other discordant effects. HDR can appropriately enhance the exposure of the shadow area, and make the exposure and details of the main body of the character better.

3. Weak light and backlight scenes

If your photo looks a little dark (which often happens if your scene has too much backlight), HDR can brighten the foreground part without diluting the right part of the photo. Which scenes are not suitable for HDR?

Of course, HDR is not a panacea. In some scenes, using HDR to take pictures will have the opposite effect. In the following scenes, it is not suitable to turn on HDR.

1, shooting moving objects

If the object you are shooting is moving (or may be moving), turning on HDR will have a chance to blur the photo. Because HDR takes three photos, if the photographed object moves between the first and second lens, the final composite effect will be unsatisfactory.

2, high contrast scene

Some photos will look better because of the sharp contrast between light and dark parts. Turning on HDR will reduce this contrast and make the photo lose its charm.

3. Colorful scenes

If the color of the scene you want to shoot is very vivid, it is not recommended to turn on HDR at this time, because it will make the color dim a lot.

The above is a brief introduction to the meaning of HDR photography of mobile phones. From this article, you can have a certain understanding of HDR photography of mobile phones, and have a simple understanding of when it is suitable for use and when it is not suitable for use. I hope it will help you.
