Who knows how to use the digital camera of PowerShot A560?

Spot metering only applies to manual gears starting from P gear, not to automatic gears starting from AUTO gear. First turn to these files, press the function key in the middle of the camera, and the adjustment menu will appear. Then use the up and down keys to adjust to the metering position, then use the left and right keys to adjust to the metering mode with only one point in the middle, and press the function key (func) to confirm. Then press the shutter button half-way to aim at the part of the green frame that needs metering, keep the shutter half-pressed, and then press the+/-key in the upper left corner to lock the exposure. Then, release the shutter and re-compose. finally

2. What are aperture priority and shutter priority? Under what circumstances are they used respectively?

As we know, Canon A series has aperture priority and shutter priority. Under what circumstances are they used respectively?

The larger the aperture, the more light passes through per unit time, and vice versa. Aperture is generally expressed as the letter "F+ value", such as F5.6, F4, etc. It should be noted that the smaller the value, the larger the aperture. For example, F4 is larger than the aperture of F5.6, and the difference between two adjacent apertures is twice, which means F4 is twice as big as that passing through F5.6. Relatively speaking, the definition of shutter is very simple, that is, the time allowed for light to pass through the aperture is expressed by numerical values, such as 1/30 seconds, 1/60 seconds, etc. Similarly, the difference between two adjacent shutters is twice.

The combination of aperture and shutter forms exposure, which is not unique under certain exposure conditions. For example, the current normal exposure combination is F5.6 and 1/30 seconds. If the aperture is increased by one step, that is F4, the shutter value at this time will become 1/60, and this combination can also achieve normal exposure. Although different combinations can achieve the same exposure, the pictures taken have different effects.

The concept of "depth of field" is involved here. The so-called depth of field means that when the lens focuses on the subject, the subject and its scenery before and after have a clear range, which is called depth of field.

A, aperture priority is mostly used when taking portraits and landscapes.

Aperture priority is to manually define the aperture size, and the camera will decide the shutter speed according to this aperture value. Because the aperture directly affects the depth of field, this mode is most widely used in ordinary shooting. When shooting portraits, we usually use large aperture and long focal length to blur the background and get a shallow depth of field, which can highlight the subject. At the same time, a larger aperture can also obtain a faster shutter value, thus improving the stability of hand-held shooting. When taking photos such as scenery, we often use a smaller aperture, so that the range of depth of field is wider, which can make the distant and nearby scenery clear, which is also applicable when shooting at night.

B, shutter priority is mostly used to shoot moving objects, such as sports, moving vehicles, waterfalls, flying objects, fireworks, water droplets, etc.

Contrary to aperture priority, shutter priority is to obtain aperture value through camera metering when the shutter is defined manually. Shutter priority is mostly used to shoot moving objects, especially sports shooting. Many friends find that when shooting moving objects, the subject is often blurred, mostly because the shutter speed is not fast enough. In this case, you can use the shutter priority mode, roughly determine a shutter value, and then shoot. And the motion of the object is generally regular, then the shutter value can also be roughly estimated. For example, the shutter speed for photographing pedestrians is only1125 seconds, while it takes11000 seconds for photographing falling water droplets.

In short, in the case of aperture priority, we can easily control the depth of field by changing the aperture size, while in the case of shutter priority, using different apertures can achieve good shooting results for moving objects. Both should be used flexibly to meet our shooting needs in different situations.

4. How to take a good portrait?

First of all, use telephoto, 3-4 times telephoto is very suitable for taking portraits, and the wide-angle end will make people look a little deformed and ugly. A telephoto of more than 4 times or even longer will make the face too flat and not vivid enough.

Secondly, the aperture takes precedence. Choosing a large aperture can make the shutter faster, reduce jitter and make the background as blurred as possible.

It is best to choose spot metering, front spot metering and exposure locking. Because other metering methods are easily affected by the color of clothes, the face exposure is not normal.

Finally, the composition. Portraits should account for 1/3- 1/2, and faces should be above 1/3 (0.6 18 from bottom to top). The portrait taken in this way will be very vivid, have visual impact and make people look good.

5. Two suggestions for shooting macro.

Taking a good macro requires attention to light and composition, which we will mention in a future post.

The first thing we need to master is how to shoot a clear macro lens without getting burnt. Just pay attention to the following two points.

First, use a tripod. My hands are unstable and I always see a paste after zooming in, so the first one is to use a tripod.

Then, use a selfie machine. We found that even if we use the bracket, when we press the shutter, we still bring jitter. The best way is to start the selfie machine.

6. How to use exposure compensation? Under what circumstances are they used respectively?

Press the+-key and the exposure compensation adjustment bar will appear. Press the left and right keys to adjust the positive and negative compensation sum, one level at a time 1/3.

After adjustment, press the+-key again to confirm.

How to apply exposure compensation?

Generally speaking, in a white environment, the photometry is low and needs to be increased, and vice versa.

A. When the shooting environment is dark and it is necessary to increase the brightness, and the flash can't work, exposure compensation can be carried out to appropriately increase the exposure.

B. When the photographed white object looks gray or not white enough in the photo, the exposure should be increased. Simply put, the whiter the more, which seems to run counter to the basic principles and habits of exposure. Actually, it is not. This is because the camera's photometry often focuses on the central subject, and the white subject will make the camera mistakenly think that the environment is very bright, so it is underexposed, which is also a common problem that most beginners are prone to make.

C, when you shoot in front of a bright background, such as in front of a sunny window, in front of a backlit scenery, etc. , increase exposure or use flash.

D. When there is a beach, snow, sunny day or white background in front of you, increase the exposure and use the flash, otherwise the subject will be very dark.

E. When shooting a snow scene, the background light is strongly reflected by the snow, and the photometric deviation of the camera is particularly large. Increase the exposure at this time, or the snow will turn gray.

F, shooting black objects, when you look at the color change and gray in the photo, you should reduce the exposure to make the black more pure.

G, when shooting in front of a black background, it is also necessary to reduce the exposure to avoid overexposure of the subject.

(Night shooting needs to increase exposure compensation to get enough exposure)

H, shooting at night, to turn off the flash, improve the exposure value, extend the camera exposure time, in order to achieve gorgeous results, which is particularly important for automatic digital cameras without manual adjustment mode. Many people who use digital cameras feel that their night shooting ability is very poor. In fact, one of the important reasons is that they didn't use the camera exposure method correctly.

First, when it is cloudy and foggy, the environment is still bright, but the actual object illumination is obviously insufficient. Without exposure compensation, the photo may be dim. Appropriate exposure compensation, plus 0.3 to 0.7, can make the brightness of the scene more natural.

J. In some artistic photography, such as taking high-profile photos, it is necessary to increase exposure compensation to form photos with great contrast and better express the author's shooting intention. Similarly, in some cases, if it is necessary to deliberately reduce the brightness of photos, the exposure compensation should also be reduced.

Being good at applying and reasonably using exposure compensation can greatly improve the success rate of your photographic works, and take photos with clear pictures, appropriate brightness and comfortable viewing, thus improving the shooting quality.
