How to learn exposure control in photography. Mastering these two basic skills is a start.

Learning to control the brightness of photos is the basic skill of beginners in photography. How to learn exposure control in photography. Then we should learn how to adjust the three elements of exposure and how to judge whether the exposure is accurate, so that we can get started easily. Mastering these two basic skills is a start.

How to learn exposure control in photography

1 three elements of exposure and exposure control

How to control exposure in photography? The three elements of contact must be learned. Refers to the aperture, shutter speed and sensitivity, and the sensitivity is set to a lower value to ensure the image quality. So often adjust the aperture and shutter speed, adjust the aperture according to the depth of field, and adjust the shutter speed according to the exposure time.

1 three elements of exposure and exposure control

Photography exposure control, aperture, shutter speed and sensitivity directly affect the exposure of photos: the larger the aperture, the brighter the picture will be; The smaller the aperture, the darker the picture brightness. The slower the shutter speed, the more the picture is exposed; The faster the shutter speed, the less exposure the picture will be.

The higher the sensitivity, the brighter the picture; The lower the sensitivity, the darker the picture. Therefore, the brightness of the photo is determined by the aperture, shutter speed and sensitivity: when the photo is dark, just open the aperture, slow down the shutter speed or improve the sensitivity; When the photo is very bright, just narrow the aperture, or increase the shutter speed, or decrease the sensitivity.

2 histogram and exposure judgment

First of all, the most direct method is to look at the photo with naked eyes after shooting, and estimate whether the exposure of the photo subject is accurate, so as to judge whether the photo is bright or dark. Finally, by adjusting the three elements of exposure, the exposure of photos can be adjusted to the correct degree. This is an effective method commonly used by most people and can be fine-tuned later.

2 histogram and exposure judgment

Judging by the naked eye may not be accurate. To judge whether the exposure of a photo is accurate, we must rely on the exposure histogram: when the pixels of the histogram are concentrated on the left, it means that the exposure is insufficient, and it is necessary to increase the exposure: open the aperture, slow down the shutter speed, or improve the sensitivity.

When the pixels of the histogram are concentrated on the right side, it means overexposure, and it is necessary to reduce the exposure: reduce the aperture, increase the shutter speed, or reduce the sensitivity. Generally speaking, this is an accurate exposure when the pixels of the histogram are concentrated in the middle and distributed in the left and right areas.
