How to use Canon SLR eos7d

In our daily study, work or life, we often see photos. The following is my collection of usage methods of Canon SLR eos7d for your reference, hoping to help friends in need.

Use of Canon 7D SLR camera

First, the vertical width of the banner defines different autofocus points.

When taking close-up portraits, we usually use a single focus, and it is best to focus on the eyes of the model. If you focus on the center point, in most cases, you need to focus first and then look at the composition, which is not only troublesome to operate, but also may be out of focus when you look at the composition again because of the movement of the camera. When shooting, it is possible to choose the autofocus point according to the situation in order to have enough time for posing, but it is unrealistic for snapshots. For many people who like conventional composition, it is better to keep an eye on the golden section. It is a good method to define the autofocus point in the most common position of the eyes according to the banner and vertical amplitude of the camera by using the function of "autofocus point and direction linkage" provided by 7D. According to my experience and the direction of hand-held camera, it is very practical to define autofocus point for portrait shooting, which can not only be convenient to operate, but also improve the success rate of snapshot. The definition of "correlation between autofocus point and direction" is not fully explained in the 7D manual. I summarized the definition process and shared it with you.

1. Set the camera focus mode to single focus, and select Av or Tv as shooting mode.

2. Press the menu key and select C.Fn.III from the second item on the right in the menu.

3. Press the setting key and use the dial to select the item 12 "autofocus point associated with direction".

4. Press the setting key and use the dial to select "1". Choose a different autofocus point ". Press the menu key several times to end the setting.

5. Turn the camera handle up, use the Q key to find the function of selecting the autofocus point, and select the focus point that you think is most often aimed at the eye position from 19 autofocus points.

6. Similarly, define the autofocus point in the downward direction of the handle.

7. Select the autofocus point in the horizontal direction.

The definition process is complete.

At this time, when you shoot, the camera will automatically focus at the focus you set according to the vertical width of the banner.

Using the custom function of 7D, let your machine have your personality, and move towards the realm of "sword and chivalry in one" in martial arts.

Second, the skill of choosing autofocus point

7D has 19 focus points, which brings great convenience to shooting and composition. But when I choose the autofocus point according to my own needs at the shooting scene, it often takes some time to get it. Because the default formula for 7D is to press the "autofocus point selection" button first, and then the focus point in the viewfinder turns red, then you can use the dial or the "multi-function control" button to select the autofocus point. In fact, the function of selecting focus can be simplified by customizing the function of control keys. You can directly select focus by pressing "multifunction control key", and you can directly return to the center focus or register the focus by pressing "multifunction control key" vertically.

The specific setting method is as follows:

1. Press the menu key and select "C.Fn.IV Operation/Other" in the second item from the left.

2. Select 1, and then press the Set key.

3. Select the last "multifunction control key" and use the dial to change "Off" in the default setting to "Directly select the autofocus point".

4. Press the Info button to select "Switch to the central autofocus point" or "Switch to the registered autofocus point". The so-called registered autofocus point is the autofocus point that I mentioned in the second article in this series, which is registered at different focus points in the horizontal and vertical directions. I am used to going straight back to the central autofocus point.

5. Press the setting key to confirm, and then press the menu several times to return, and the setting is complete.

I really don't understand why Canon doesn't set the simple operation mode as the default, and why users have to go around so many times to achieve simple operation.

Third, use the viewfinder electronic level.

I often see that the horizons of many films posted by novices are tilted. Although it can be adjusted later, sometimes it will affect the composition. 7D provides a very convenient electronic level. When shooting, you can display the horizontal status of the camera on the LCD by pressing the INFO button twice. This is very convenient when shooting with a tripod, but it is a bit inconvenient to shoot with a viewfinder. The user-defined button function of 7D can define the M-Fn function as the electronic level of the viewfinder. After the definition is completed, as long as you press the M-Fn key in the shooting state, you can see the horizontal state of the camera in the viewfinder (judged by the jumping red dot on the autofocus point). Personally, I think it is still very convenient.

The specific setting method is as follows:

1. Press the menu key and select "C.Fn.IV Operation/Other" in the second item from the left.

2. Select 1, and then press the Set key.

3. Select "M-Fn" on the right side of the first row, and use the dial to change "FEL" in the default setting (the flash exposure lock is changed to "viewfinder electronic level").

4. Press the SET key to confirm, and then press the menu several times to return.

In addition, the setting key is off by default, and the setting key can also be defined as the speed control screen, which is consistent with the operation of cameras such as 5D2, depending on personal habits.

Fourth, autofocus with your thumb.

Focusing photometry with index finger half pressing shutter was once a necessary technique for photographers who used SLR autofocus. After 7 days, this technology is basically no longer needed. 7D provides a separate AF-ON button. When taking pictures, you can press AF-ON with your thumb to start autofocus and photometry. We can use the button customization function of 7D to set the "metering and autofocus start" function of the original "half-press shutter" to "start metering", so that when taking pictures, you can press the AF-ON button with your thumb to start autofocus and release the button.

Compared with half shutter autofocus, thumb autofocus has the following advantages:

1. When re-composing after focusing, it is not necessary to keep the index finger in the state of half-pressing the shutter. When AF-ON focuses, you can easily re-compose by pressing your thumb. Just press the shutter directly after the composition.

2. When using a full-time manual lens, you can directly switch to manual focusing at any time without pulling the AF-MF button on the lens, because the camera will not perform autofocus operation when pressing the shutter. If the AF mode of the lens is not set to MF mode, it will easily cause the camera to start autofocus when the shutter is pressed, which will lead to defocus.

3. When shooting scenery or night scenes with a tripod, as long as the focal length is adjusted, you don't have to worry about the out-of-focus problem caused by the camera starting "autofocus" every time the shutter is pressed.

4. When using artificial intelligence servo autofocus shooting, if the camera wants to autofocus an object that the photographer does not expect, you can release the AF-ON button to stop autofocus.

After using it for a while, I found that it was quite easy to use except that I forgot to focus occasionally because I was not used to it.

The specific setting method is as follows:

1. Press the menu key and select "C.Fn.IV Operation/Other" in the second item from the left.

2. Select 1, and then press the Set key.

3. Select the first item "Half Press Shutter" and use the dial to change the default setting of "Photometry and autofocus Start" to "Start Photometry".

4. Press the setting key to confirm, and then press the menu to return.

Setup is complete.

7D has a very powerful customization function. To achieve the goal of "man and sword in one", you need to define 7D according to your own habits, so that the camera has its own personality!

V. Automatic exposure locking

Beginners often confuse photometry with focusing. Although both metering and focusing are done with the shutter half pressed, their tasks are different. The task of photometry is accurate exposure. The so-called accurate exposure means that photos can restore the light situation on the scene or realize the photographer's exposure idea. The task of focusing is to ensure that the photo is clear, or to make the photographer want to be clear. My experience is that in most cases, evaluation photometry can ensure the accurate exposure of photos, but when shooting in Gao Fancha or backlight, spot photometry or central focus photometry can better realize the photographer's intention. Whether spot metering or center focusing metering is used, if the metering point does not coincide with the focus, exposure locking is needed.

Take 7D as an example to explain how to measure and focus correctly (the measuring point does not coincide with the focusing point);

1. First, aim the lens at the metering point and press the shutter half way to finish metering.

2. Press the exposure lock button (*) to release the shutter.

3. Quickly aim the lens at the focus point and press the shutter half to focus.

4. After focusing, press and hold the shutter for composition and framing.

5. Press the shutter to end shooting.

Which is better, Nikon or Canon SLR?

If you simply compare Canon and Nikon, the answer is: just as good. But there are still some differences between them. These differences may help you decide which brand to choose.

What's the difference between Nikon and Canon SLR?

1. Generally speaking, Nikon's low-end lens is more realistic (especially the new lens). For example, more exquisite workmanship and more complete accessories.

Generally speaking, Canon's top lenses are cheaper. For example, Big Three Yuan (3 top zoom lenses).

Generally speaking, Nikon's flash system is more interesting.

Canon camera can switch almost all lenses, including those 60 years ago, and of course Nikon lens.

Most photographers who shoot sports themes use Canon cameras.

6. Canon 5D Mark II has powerful video functions, and many professional video studios shoot with 5D Mark II.

7. Nikon D2/D3 model is a purchasing machine of NASA, serving on the International Space Station.

8. Canon's DPP software can be downloaded for free, and Nikon's NX 2 software should be purchased separately.

Finally, we should understand that the relationship between Canon and Nikon is not completely life-and-death. Their products often show the characteristics of dislocation competition. If you want a simpler answer, it is: buy the most expensive camera within the budget, whether it is Canon or Nikon.

Development: Canon SLR photography skills

Canon SLR photography skills one:

The first trick: use a range finder.

In fact, friends who use rangefinder know that after connecting rangefinder, the camera can zoom in on distant objects. Similarly, when taking macro shots, the focal length of the camera will not change in the near future when using the rangefinder, so the shot object can be larger than the original one. However, there is a limitation and two disadvantages in using this trick.

Restrictions:

That is to say, it can only be used on cameras with weak macro ability or the telephoto end of cameras. Because the macro ability of DC is too strong, the macro is often in the wide-angle section, and the distance often reaches 1 ~ 2 cm. You may not be able to focus after connecting the rangefinder. For SLR cameras, there is no need to care about this problem because the focusing distance is relatively large.

Disadvantages:

1. After the rangefinder is used, the aperture of the lens will become smaller. Although the aperture value displayed on the camera will not change, it is no problem to take pictures according to the result of photometry in the camera. But in fact, the real aperture value should be the displayed aperture value multiplied by the multiple of the rangefinder: for example, after a lens is connected with a 2-fold rangefinder, when the aperture is F2.8, the actual aperture value is 2.8×2=5.6. At this time, although you can still shoot according to the metering results, because the actual aperture becomes smaller and the focal length becomes longer, at this time, the shutter speed will slow down to the point where it is blurred due to slight shaking when holding, so it is best to use a tripod to ensure the clarity of the picture.

2, rangefinder is often not light, a bit heavy. Therefore, it is easy to be top-heavy when connected to a camera, and even if it is placed on a tripod, it cannot be absolutely stable. When you press the shutter, the vibration will also cause the shooting to fail. It is best to take a selfie or shoot with a wired release. Minimize vibration.

The second trick: use close-ups.

Close-ups are actually convex lenses. There are groups of three, and there are also single pieces. There are several specifications such as+1, +2, +3 and +4. The larger the value, the greater the magnification. It can be used in one piece or in multiple pieces, which is very flexible.

Advantages:

The investment is not big, generally 200 ~ 300 yuan, you can buy a set of three tablets. Flexible and flexible, the lens does not take up so much volume as a rangefinder after all. Several pieces can be combined at will, with high flexibility. When using close-ups, the aperture will not be as narrow as when using rangefinder, so it can be used more boldly than rangefinder. The last lens of some wide-angle additional lenses can be detached for close-up, so people who have wide-angle lenses and are sure to buy them should pay attention. Oh, did you buy such a useful function, hehe.

Disadvantages:

This method uses close-up lens, which changes the optical structure of the lens, so the imaging quality will be degraded to some extent. But there is a solution. First of all, if you want to install a filter, you must buy an adapter ring. Generally, there are two options for the adapter ring: large caliber and small caliber. At this time, we still use a larger caliber. If it is a DC or SLR with a filter line in front of the lens, it is best to buy a larger adapter ring and use a larger close-up lens. The filter with large aperture can make DC use the central part of the filter to image, avoiding the parts with poor imaging quality in corners and getting better imaging. Secondly, when using close-ups, it is best to use the telephoto end of the camera, which also makes full use of the imaging in the middle part.

Canon SLR photography skills 2:

Beginners are prone to make mistakes: there is no distinction between priorities and priorities.

You can often see people taking pictures in the park. The photographer is far away from the subject, and the camera used does not have a zoom lens. We can conclude that this will not be a successful photo shoot. Because the photographer can't figure out what he wants to show, is it people or scenery? In terms of composition arrangement and theme conception, photos can only have one theme, and other contents should be theme-centered, which can serve as a foil and better highlight and express the theme connotation. As far as outdoor scenery photos are concerned, there are generally the following two situations:

(1) People-centered. Most photography falls into this category. We travel to scenic spots or take a walk in the park. Taking pictures, taking pictures is mainly a good memory in the future. We can choose representative buildings, flowers, grasslands, lakes and other backgrounds to set off the protagonist. People should occupy the main position in the picture and become the visual center. If we can further vividly reproduce the inner temperament of the characters through expressions, movements and other contents, it will definitely make it worth collecting forever!

(2) Take the scenery as the center and the characters as the decoration. It is often used to express special scenery. For example, shoot a big Buddha statue, and compare the size of the Buddha statue with a small proportion of people in the picture to show the great achievements of ancient civilization; Another example is the Prince's Bay Public Garden in Hangzhou. During the lawn maintenance in spring, a large area of green grass was enclosed and extended to the dark green hills in the distance. In addition, the bubbles blown by children drifted with the wind, forming a wonderful artificial natural landscape. In composition, green is the main body, and people decorate its vitality to show the beauty of the paradise on earth. Yin-yang face and big black face "Yin-yang face" means that the portrait face is illuminated with 90-degree side light, half black and half white. This shooting method often shows a strong dramatic effect and is not suitable for life photography. Big black face refers to the consequences of underexposure of backlit portraits. If you shoot the back or side of the character, you can achieve the effect of silhouette. When shooting a frontal portrait, it is best to fill the light appropriately, such as using tools such as flash or reflector to fill the light. Beginners often do not pay attention to the role of light in the overall composition, or always habitually use a certain kind of light, so it is difficult to improve. Understand the basic knowledge of light first, then practice it, and dare to break through, so as to surpass yourself. Due to the graphic modeling characteristics of photos, it is easy to inadvertently "graft" distant branches, telephone poles, etc. to the main characters, as if they grew from the head, making the original beautiful photos fly in the ointment. In fact, as long as you pay a little attention to changing the angle when shooting, you can avoid it.
