How to handle macro photography with three tricks

1, using rangefinder: In fact, all friends who use rangefinder know that after connecting the rangefinder, the camera can make things in the distance bigger. 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. Limitation: It can only be used on cameras with weak macro capability 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: 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. Rangefinders are often not light, but a little 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.

2. 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: Low investment, 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 will reduce the imaging quality to some extent, because the close-up lens changes the optical structure of the lens. 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.

3. Inverted lens: This method, as many people have said, is to invert the lens of the SLR-generally use a 50mm pan/tilt and connect it to the front of DC or SLR through a double pan/tilt. This method has the largest magnification and the best imaging quality. However, the double head is relatively difficult to find, inconvenient to operate, poor mobility, and there are still top-heavy problems. Generally speaking, overexposure is rarely used, so it may be the most wonderful shooting method, but it is not the most practical.
