Beginners learn photography basics quickly

The most basic thing to learn photography is to master the basic knowledge of photography. So today I will sort out the basic knowledge of photography for you. Ladies and gentlemen, what do you have? Remember carefully!

Three elements of exposure

hole

The larger the aperture value, the less light entering, the smaller the aperture and the smaller the blur.

The smaller the aperture value, the more incoming light, the larger the aperture and the greater the blur.

shutter

The larger the shutter value, the more light enters.

The smaller the shutter value, the less light enters.

The bigger the shutter, the faster the speed.

The smaller the shutter, the slower the speed.

Sensitivity ISO

The larger the ISO value, the more light enters, the brighter the photo and the worse the image quality.

The smaller the ISO value, the less light entering and the darker the photo. The better the picture quality.

Focus mode

Single autofocus (AF-S)

Generally, after half pressing the shutter, there will be a "drip ~" sound in the camera, indicating that the focus is successful. This mode is suitable for shooting some still lives, portraits and landscapes. It is recommended that novices use this mode.

Continuous autofocus (AF-C)

This mode is suitable for shooting moving objects. During shooting, the shutter stays in focus and can follow the subject to stay in focus until the shooting is over. Suitable for catching birds, athletes, etc.

Intelligent autofocus (AF-A)

The most commonly used focusing method, the camera automatically selects the focusing method according to the shooting environment, which may be single focusing or continuous focusing.

Pure manual focusing (MF)

According to the shooting environment, manually adjust the focal length, and there will be absolutely no mistakes. When autofocus fails, we need to take manual focusing. Generally suitable for shooting subjects that are too small or too close, such as macro.

measure

Evaluation photometry

The most common metering mode can be used in any situation. The camera will automatically adjust the exposure of the shooting scene, but it is not suitable for use in strong light, such as 12 noon. Simple operation, suitable for novices.

Partial measurement

It means that the camera will measure light in the central part, which is very suitable for scenes where the photographer occupies a small proportion in the picture, so that the measurement will be more accurate than the evaluation measurement, and the frequency of use is not high, so it is not recommended.

Central key photometry

A commonly used metering mode, in which half of the subjects occupy a larger picture, and the metering range is larger than that of part of the metering, which is suitable for shooting landscapes, people or people in the center of the picture.

Spot photometry

The measurement range of point measurement is more accurate than that of partial measurement. It measures 3% of the screen area, for example, even if the object is not in the center. Can fully show the subject of shooting, suitable for taking some close-up and close-up photos.

Teach you focal length.

The focal length of the lens will be marked on the camera lens. For example, 50 mm has only one number, indicating that it is a fixed-focus lens with a focal length of 50 mm. And 18-200mm has two numbers, indicating that the focal length of the lens is within the range of 18 to 200, which means that it belongs to a zoom lens and the lens can rotate.

What is a telephoto/fixed focus/wide angle lens?

The smaller the focal length, the wider the wide angle and the wider the picture taken by the lens. The larger the focal length, the longer the focal length, such as 200 mm When you turn the lens and enlarge the object, the picture will get closer and the content will be less. The telephoto/wide-angle lens is suitable for taking landscape photos. The fixed-focus lens is suitable for taking portraits at close range.

What is depth of field?

The smaller the focal length, the greater the depth of field and the clearer the background. It is used for scenery.

The greater the focal length, the smaller the depth of field and the more blurred the background. Used of portraits.

Exposure value reference

AV aperture priority mode:

Shooting scenery: F8-F 1 1 (with medium aperture and small aperture)

Portrait shooting: Maximum aperture below F2.8

Shooting still life: the maximum aperture is lower than F2 (the background is blurred and highlights the subject).

Macro shooting: F8-F 1 1

Shooting Star Man/Slow Gate: F 1 1-F20

Television shutter priority mode

Normal portrait posing: 1/80 seconds or more (recommended 100 or more)

Dynamic snapshot: running 1/500 seconds/birds/waterfalls:11000 seconds ~ 1/2000 seconds; Slow door/taillight drawing/lighting drawing: 1/30~ 1/4.

M-gear pure manual mode

Shooting galaxy: 30 seconds IS03200-6400 F2.8

white balance

White balance (K) controls the color of the picture and affects the color temperature of the photo.

How to adjust the value of white balance

If the value of k >: 5000K, the color of the scene is reddish and belongs to warm tone.

Has a warm and stable atmosphere effect; Suitable for shooting indoor effect portraits.

When the k value is 4000-5000K, it belongs to the effect of normal middle tone and the real environmental effect of white tone; Suitable for shooting places with good light, portrait/style is ok. If the value of k is
