How to adjust the exposure of the camera

1 program exposure mode

The function of program exposure mode is often ignored, thinking that it is something that only a few people use. But if we don't want to focus on the aperture or shutter, the program exposure mode can help us pay more attention to composition and timing.

2 exposure compensation adjustment parameters

When the camera is in program exposure mode, we can use the dial or wheel on the camera to control the combination of aperture and shutter, and do basic creative control on depth of field or motion blur without changing the exposure mode.

3 bright background

If the background brightness of the picture is much higher than the subject, direct shooting may lead to underexposure. In order to avoid this problem, it is necessary to set the exposure compensation to a positive value, such as 1 or 2, to ensure the correct exposure of the subject.

The background is dark.

Shooting in front of a dark background often leads to overexposure. In order to avoid this problem, it is necessary to set the exposure compensation to-1 or -2 to balance the screen exposure when using average metering.

5 high-profile scenery

In the face of bright scenery, it is necessary to appropriately increase the exposure compensation value of the camera to ensure correct exposure. You can start at 2.

6 Dark-tone landscape

Dark tone images contain a lot of shadow information. In order to ensure the correct shooting of such works, it is necessary to use a lower exposure compensation setting, such as -2.

7 gradient gray filter

If the brightness of the picture is obviously uneven, you can use the gradient gray filter to balance the exposure difference between the top and bottom or both sides of the picture.

8 use spot metering

Set the camera to spot metering mode and aim at the midtone scene we want for metering shooting. This measurement mode is very accurate.

9 built-in HDR

If the camera provides HDR optimization, we can turn it on to get richer highlights and shadow details.

Exposure around 10

By taking two or more photos of different exposure value and combining them together, we can overcome the strong contrast between light and shade in the environment.

1 1 aperture priority

Aperture priority mode is the most commonly used exposure mode. You can control the depth of field and the exposure of the picture at the same time. Setting the aperture below f/4 can effectively blur the foreground and background of the main body of the picture; Setting it to a value of f/ 16 or greater can ensure that the picture is consistent and clear, thus retaining more details.

12 shutter priority

We can achieve the effect of solidifying or blurring moving objects by controlling the shutter speed. Using a shutter of11000 seconds or faster can make a high-speed moving object look stationary, while a shutter of115 seconds or slower will bring obvious motion blur.

13 exposure lock

After the subject fills the screen, hold down the exposure lock button to lock the current exposure. In this way, even if we adjust the picture composition to make the background too bright or too dark, it will not change the exposure of the subject.

14 histogram

Histogram can provide us with detailed and useful information about the exposure of the picture, which should be viewed immediately after shooting.

15 Use manual exposure

If you have enough energy and experience to adjust the aperture size and shutter speed, you can set the camera to manual exposure mode. Most cameras provide auxiliary exposure reading display in manual exposure mode, but the best detection method is to actually take a photo and watch it in playback.
