How to take a photo with a pure black background with Huawei mobile phone?

There are many kinds of such photos circulating on the Internet. In a black background, only the subject has normal exposure, and the black background plays an obvious role in setting off the subject, which can further set off the details of the theme itself. Common such photos are flowers, candlelight and so on. Today, I would like to take this opportunity to explain in detail how to take photos with black background and how to measure light.

The most intuitive way to shoot this kind of photos is to put the theme on a black background, such as black background paper or absorbent cloth. The advantage of this is that shooting doesn't require much skill and post-production. Of course, this is the way of shooting, so this post is meaningless. We know that photography is the art of light, and how to use light is the essence of photography. Today, let's talk about the metering method in professional mode.

Huawei introduced the professional mode of professional camera into mobile phone photography from EMUI4.0, which added a lot of color to the playability and professionalism of mobile phone photography. Huawei smartphones that support professional mode can use this mode. Let's take Huawei P40 Pro as an example. Click to enter the professional mode of mobile phone, and there will be a row of parameters, namely metering mode [M], sensitivity [ISO], shutter [S], exposure compensation [EV], focusing mode [AF] and white balance [WB]. Today, we mainly test two parameters, metering mode [M] and exposure compensation [EV].

Click metering mode [M] and you will find three metering modes, namely matrix metering, central button metering and point metering. Matrix photometry is a widely used photo photometry method and the most commonly used photometry method. The central focus measures the whole picture, but the central area accounts for the largest proportion; Spot metering is to measure 2.5% around the screen metering point: simply speaking, it is a metering method from the whole to the part.

Exposure compensation [EV] is better understood. As the name implies, exposure compensation can change the default exposure value of the camera, making the photo brighter or darker. Suitable for increasing the value when underexposed and decreasing the value when overexposed. In addition, exposure compensation has always adhered to the principle of "whitening and reducing black", that is, exposure compensation should be increased when shooting white objects and decreased when shooting black objects. Of course, white and black correspond to color depth changes, and exposure value also depends on the specific situation.

Next, let me show you the proofs when shooting. At this time, both the sensitivity [ISO] and the shutter [S] are automatic by default. We will share the meaning and function of these parameters in the next issue. For this photo, we need to pay attention to the professional spot metering mode and the exposure compensation [EV] value of -0.3. In other words, you can take such a photo by mastering these two parameters.

Not much to say, just go to the tutorial: 1. Click on the photo APP, professional mode; 2. Place the subject in the center of the picture; 3. Click metering mode [M] and select spot metering; 4. Adjust the angle of the picture to find the most suitable angle until the background is completely black; 5. Click Exposure Compensation [EV] to reduce the value when the background of the picture is not completely black, depending on the real-time feedback of the picture.

Of course, the imaging of professional mode adjustment parameters may have a certain gap with the ideal effect, and the parameters such as contrast and brightness can be modified by "Edit-Adjust". By increasing the contrast and reducing the brightness of the dark part, the picture is adjusted to achieve satisfactory results.

Hope to adopt. Good luck.
