What should I do if I take pictures with my mobile phone?

Lead: Hello everyone, it's time for photography class again. Photographers may not understand HDR, but fruit powder must be familiar with it. Taking photos with iPhone is very common every day. But how does it work? Let's be specific.

HDR = high dynamic range = high dynamic range = When the difference between the brightest and darkest parts of an object is particularly large, turning on HDR in photography can overcome the shortcoming of limited dynamic range of most camera sensors and superimpose multiple photos with different exposures into one; In a word, HDR can enrich the details of the bright, dark and bright/dark parts.

For example, chestnuts, when the outdoor light is sufficient, the portrait taken in the backlight may look like this on the left. You don't think so. This face is not right. You focus your face and shoot it in the middle, but the background is too bright to see clearly! How can I take a photo with such a balanced exposure on the right? You need to turn on the HDR function and pay attention to the character touch screen.

After the HDR of iPhone is turned on, there will actually be three photos of continuous shooting, corresponding to underexposure, normal exposure and overexposure, and then they will be combined into one photo. The following two pictures are the original picture (left) and HDR picture (right) automatically saved by the system during shooting. Due to the strong light outside, the indoor objects are darkened as a whole, and the buildings outside the window are also bright. But under the' ‘HDR effect' on the right, the photo has been obviously improved.

When do you use HDR?

It probably includes but is not limited to: outdoor backlit portraits, the scenery under strong light (blue sky, white clouds and fragrant grass are the most classic), and indoor shooting when there is strong light through the window.

Better turn off HDR!

It probably includes, but is not limited to, shooting objects in motion. At that time, the lighting conditions were already very good (the distribution was balanced, bright enough, and there was no sudden highlight).

With a little skill.

If you don't want the system to save the original image and HDR image for you at the same time when using the HDR function, you can set >; Photos and cameras > keep the photos exposed normally and close them.

After reading it, I don't know if I have it! Using HDR function can definitely help you solve a lot of embarrassment when taking pictures. Try next time, maybe it will be duang!
