Three elements of exposure (aperture, shutter and sensitivity ISO)
The larger the aperture value, the darker the photo and the less obvious the background blur. The smaller the aperture value, the brighter the photo and the more obvious the background blur.
The larger the shutter value, the brighter and slower the photo is, and the easier it is to blur the subject. The smaller the shutter value, the darker the photo, the faster the speed, and the easier it is for the subject to be clear.
The greater the sensitivity value, the brighter the photo! The more obvious the noise in the photo, the smaller the sensitivity value, the darker the photo, and the less the noise in the photo.
Three elements of depth of field (shooting distance, focal length and aperture)
distance
The closer the shooting distance, the shallower the depth of field and the more obvious the background blur. The farther the shooting distance, the deeper the depth of field, and the less obvious the background blur.
focal distance
The longer the focal length, the larger the subject, the shallower the depth of field, the shorter the focal length, the smaller the subject, the deeper the depth of field and the clearer the background.
hole
We can adjust the depth of field by adjusting the aperture size. The larger the aperture, the shallower the depth of field and the more blurred the background.
Large aperture is suitable for shooting: portrait or still life.
Small aperture is suitable for shooting: landscape shooting
measure
Evaluation photometry: intelligently analyze the brightness value of the whole picture, and take the average value as the reference of picture exposure. Evaluation photometry can accurately measure the normal exposure of the shooting picture.
Partial metering: 10%~ 15% pictures use metering. When the subject is small and there is obvious brightness gap with the environment, partial metering can ensure the normal exposure of the subject.
Spot metering: 3%~5% of the picture can be accurately metered, which can ensure accurate exposure when shooting small objects and normal exposure when shooting backlight subjects.
Center focus average photometry: average photometry is carried out on the central area of the picture 1/3, which is suitable for the situation that the subject is concentrated in the center, and also takes into account the edge brightness measurement, and is suitable for large groups of photos.
Focus mode (auto focus: AF-S, AF-C, AF-A, manual focus)
Single autofocus (AF-S): This focusing mode is more suitable for shooting still objects. When the lens is aimed at the subject and the shutter is half pressed, the camera will focus once.
AF-C: AF focuses by pressing the shutter half. The camera will lock the target object or lock the focus area, which is suitable for shooting moving targets, such as runners, moving vehicles, animals, babies and so on.
Intelligent autofocus (AF-A): This mode combines continuous focusing and single focusing. Half-pressing the shutter can lock the subject at the intersection for single focusing, and switch to continuous autofocus for tracking shooting when the subject moves.
Manual focusing: A method of focusing by manually turning the focusing ring to adjust the camera lens so as to make the photos taken clear. This method largely depends on the human eye's resolution of the image on the focusing screen, the photographer's proficiency and even the photographer's vision.
