Do you know the basics of getting started with cameras?

The three elements of light and exposure refer to aperture, shutter speed, and sensitivity ISO; aperture is the aperture size of the light entering the camera, shutter speed refers to the length of time the light enters the camera, as well as sensitivity ISO, white balance, exposure compensation, Parameters and adjustment items such as metering and metering mode, focus and focus mode. The following is a detailed introduction:

1. The three elements of exposure and exposure refer to aperture, shutter speed, and ISO; exposure is simply the brightness of our picture. Too bright is overexposure, also known as overexposure, and too dark is underexposure, also known as It is underexposure; there are relevant light meter data for reference;

2. Aperture is the aperture size of the light entering the camera. The larger the aperture (the smaller the value), the larger the light entrance aperture and the more light input, so the greater the exposure, the higher the screen brightness, the shallower the depth of field, and the blurred background. The higher the degree (the more blurred the background), and vice versa;

3. The shutter speed refers to the length of time that the light enters the camera. It refers to the period from when the shutter is opened to closed. dark, and vice versa;

4. Sensitivity ISO, the sensitivity is the sensitivity of the photosensitive element to light. The same light brightness, the higher the sensitivity, the more sensitive the photosensitive element is to light, and the brighter the picture. High sensitivity will produce noise. Generally, it is recommended to use it with caution ;

5. White balance, simply put, is the setting of the K value of the color temperature in the camera. Generally, the K value is calculated as the middle value in 5000 as the benchmark: when the picture is bluish and cold, adjust the K value below 5000; the picture is yellowish and warm. When tuning, adjust the K value to above 5000;

6. Exposure compensation, exposure compensation is the function of adding or reducing light to the brightness of the screen after our metering. This function is set to prevent the metering from failing in some cases. There is a [white plus black minus] In principle, if the picture is dark after shooting, you can adjust the exposure compensation in the positive direction to increase the exposure, and vice versa;

7. Metering and metering mode, metering is a process in which our camera measures the light on the screen; the metering modes mainly include evaluative metering (average metering), center-weighted average metering, and spot metering;

      Evaluative metering (average metering) is that the camera divides the screen into small squares, measures the light of each small square separately, and then counts and averages the final exposure, but it is not practical for scenes with large light ratios; Focused average metering is to perform average metering on the most central area of the camera. This is not the whole picture, but the most practical way of metering, because most of our cameras rely on metering on the most central area of the screen. It is also applicable to the widest range of occasions; spot metering, which is to measure light on a small point, is the most accurate light metering method, which can ensure that the light metering of our subject is the most accurate;

   8. Focusing and focusing mode, focusing is the process of making our subject shoot clear; manual focus, relying on manual adjustment of the zoom ring to adjust the clarity of the subject, generally used when the automatic focus cannot meet the needs, after all, manual adjustment Time-wasting; single autofocus, focus on the subject once, suitable for shooting still life; continuous autofocus, continuous focus on the object after half-pressing the shutter, the object moves, keep pressing the shutter halfway, the focus point will follow the moving object, suitable for Shooting moving objects; fully automatic focus, using the camera to determine the focus point by itself, and automatically switch between single-shot AF or continuous focus, depending on whether the subject is moving;
