Photography skills that must be learned at macro.

Macro photography can let us see a different world. The picture in macro photography is beautiful. How to take a good macro photo? The following are my photography skills for macro finishing, I hope to help you!

The first trick: use a range finder.

In fact, friends who use rangefinder know that after connecting the 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. Third, reduce the aperture appropriately. The aperture is small and the lens edge is used less, which can further improve the imaging quality.

Combined with several measures, the degradation of imaging quality will not be too obvious.
