What are Canon SLR photography skills?

SLR cameras have become an important part of many people's amateur cultural life, which has also led to a photography boom in society. I sorted out the skills of Canon SLR photography and shared them with you!

Canon SLR photography skills: advanced strategies for entry-level players, two strokes to get macro photography.

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: a common problem for beginners

Regardless of priority

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. 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.
