Exposure mode: There are six common shooting modes for cameras.
1, A+ automatic mode: In this mode, the aperture, shutter and sensitivity are all set automatically by the camera, and you can shoot by pressing the shutter, which is suitable for novice Xiaobai.
2, P program automatic mode: In this mode, the aperture and shutter are also camera settings, as well as other parameters, ISO, focus area, etc. You can set it yourself, which is suitable for beginners.
3.Av aperture priority mode: In this mode, parameters such as aperture and ISO can be set by yourself, and the shutter is automatically matched by the camera.
4. TV shutter priority mode: In this mode, parameters such as shutter and ISO can be set by yourself, and the aperture is automatically matched by the camera.
5.M full manual mode: In this mode, any parameter can be set manually by yourself, and the degree of freedom of M file is relatively high, but it requires certain photographic experience, so it is not recommended for beginners.
6. Door B: The shutter release mode is completely controlled by the photographer. The length of shutter time is completely determined by the length of time the photographer presses the shutter, so it is also called "manual shutter".
Set shutter
The larger the shutter value, the slower the shutter speed, the longer the light input time and the brighter the picture, which is suitable for recording tracks.
The smaller the shutter value, the faster the shutter speed, the shorter the light entering time and the darker the picture, which is suitable for capturing and recording moments.
Set aperture
The larger the aperture value, the smaller the aperture, the less light entering, the darker the picture, and the less obvious the background blur. Suitable for taking scenery and photos.
The smaller the aperture value, the larger the aperture, the more light, the brighter the picture and the more obvious the background blur, which is suitable for shooting portraits.
Set sensitivity
The lower the sensitivity value, the less sensitive to light, the darker the picture, the less noise and the better the picture quality. The sensitivity of 100~200 can be used under daily normal lighting conditions.
The higher the sensitivity value, the more sensitive to light, the brighter the picture, the more noise and the worse the picture quality. Don't be afraid to improve the sensitivity in poor light.
Exposure indicator scale
Generally speaking, if the exposure indicator ruler is exposed normally at the position of 0.
A negative value indicates underexposure, and a positive value indicates overexposure, which means that the brightness of the photo is normal, bright or dark.
Flash exposure compensation
When using flash to fill the light, you can increase or decrease the amount of light to change the shooting brightness.
Automatic brightness optimization
You can automatically adjust the brightness and contrast of the picture. When the contrast of the shot picture is too large, the darker part of the picture will be adjusted to natural brightness after opening.
It can be adjusted to weak/standard/strong/off according to the needs of the current picture.
Photo style
According to the desired picture effect, adjust the color, clarity, contrast and other parameters of the picture, so that the picture can be straight out to achieve the desired picture effect.
Sharpness:
Sharpness means sharpness, high sharpness, clear photos, vivid details, low sharpness, soft photos and blurred details.
Contrast:
Is contrast, usually light and dark contrast. The contrast is small, and the light and dark details of the picture are soft, but the whole is gloomy and the tone is dull.
The contrast is large, the contrast between light and dark details of the picture is obvious, the overall level is clear, and the tone is bright, but some details of light and dark parts will be lost.
Saturation:
Saturation is vividness, high saturation, brighter colors, low saturation, smaller color contrast, and photos tend to be medium gray.
Tone:
After increasing hue, the back is yellow, and after decreasing hue, the picture is red.
white balance
White balance mode: auto, sunlight, shadow, cloudy day, tungsten lamp, incandescent lamp, K value, etc.
Can restore the color of the object itself in different light, can also achieve special tone effect, and can also be used to adjust the temperature of the picture.
White balance offset
The position of the white point in the coordinates is offset, and different tones can be adjusted.
A- reddish;
B- blue;
G- greenish;
M-magenta.
Automatic focus selection
There are two kinds of autofocus point selection: manual selection and automatic selection.
Manual selection is single point focusing. By pressing the up, down, left and right keys to select the position of the focus, the focus is more accurate.
Driving mode
You can choose single shot, continuous shooting, timed shot, silent shot, etc. Single shot is suitable for still life, while continuous shooting is suitable for moving objects.
Silent shooting is suitable for meetings and other scenes, and regular shooting is suitable for taking family photos or selfies.
Photo format
There are two commonly used photo formats: JPEG format and RAW format.
JPEG: A format of system compression, which takes up less space and is easy to browse, and is suitable for direct photography.
RAW: uncompressed format that takes up a lot of space and is convenient for post-processing. The specific parameters of the photo remain intact and are suitable for post-processing.
Focus mode
There are two focusing modes: manual focusing and autofocus.
There are three autofocus modes: single autofocus, artificial intelligence servo autofocus and artificial intelligence autofocus.
Single autofocus: When the shutter is half pressed, the camera only focuses once, which is suitable for shooting still life.
Artificial intelligence servo autofocus: the shutter is not loose and the camera keeps focusing. Suitable for shooting moving objects.
Artificial intelligence autofocus: the combination of the first two is suitable for shooting static and moving objects.
measure
Two commonly used measurement modes: evaluation measurement and field measurement.
Evaluation metering: The camera will consider the overall brightness of the picture, which is the most commonly used metering mode when the overall brightness of the picture is relatively uniform.
Spot metering: When metering a specific point, the camera will selectively highlight a certain part, which is suitable for pictures with large brightness contrast, such as backlight shooting.
