Philosophical significance of photography

What is the philosophical significance of photography? In order to retain the memory more clearly. But SLR photography is different from traditional photography, especially focusing. Master the basic skills of SLR photography, let us seize a better moment. Let's follow me to understand the philosophical significance of photography.

The philosophical significance of photography 1 First of all, the promotion strategy of entry-level players, three 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. Thirdly, the imaging quality can be further improved by appropriately shrinking the aperture, which is small and has few lens edges. Combined with several measures, the degradation of imaging quality will not be too obvious.

Philosophical significance of photography II. There are two types of tourism photography:

1, one is to take photos as a souvenir "a trip here", mainly to take records;

2. One is to take photography as the other eye of tourism discovery, focusing on creation. If you belong to the former, it is enough to have a perfect "fool" camera or a mass camera with a fixed lens.

Second, but if you are an amateur photographer, the following equipment may be necessary:

One or two SLR cameras with good performance allow you to shoot with two kinds of films at the same time. Two lenses with different focal lengths (including 28mm wide angle and 200mm medium telephoto). Others such as flashlights, hoods, filters, balloon brushes, spare batteries and small notebooks are also essential. Bring as much film as possible, because the film sold in tourist attractions is not only expensive, but also the quality is difficult to guarantee. Many photographers like to carry a stupid and heavy tripod. In fact, there are not many opportunities to actually use tripods during travel.

Third, there are two reasons:

1. During the tourist season, the scenic spots are crowded and the schedule is very tight. Without enough time and space, the advantages of tripod can't be brought into play.

2. In many cases, it is not suitable to use a tripod, such as on a hillside, on water or on the move. At this time, the tripod can only become a burden and a burden.

In contrast, a monopod is much lighter and more practical, but most people don't have a monopod. According to my experience, I just need to bring a mini tripod, spend a few dollars to buy the cheapest crutch after going to the scenic spot, and fix the tripod on the handle of the crutch, and it becomes a simple monopod. When you want to use crutches, press them on the ground, rocks or other objects, and you can shoot smoothly. In addition, all equipment should be operated according to procedures before departure to ensure that they can work normally.

Fourth, shoot according to the theme and theme.

Everything on the journey is a brand-new world for you, which can make you have the impulse to shoot, such as natural scenery, places of interest, folk customs and so on. Before shooting, you should classify them into themes, and then choose the best angle according to your previous understanding and feelings at that time. Shooting should be focused and themed, which can not only reflect the style of people and things, but also express their subjective feelings.

For what you think is important, take more photos of different films from different angles or according to different camera combinations. This seems to be a waste of film, but it greatly improves the probability of success, avoids a "miss" and leaves a lasting regret.
