How to handle macro photography with three tricks

1. Use the range finder: In fact, all friends who use the range finder know that after connecting the range finder, the camera can enlarge the distant objects. Similarly, when taking macro shots, the focus distance of the camera will not change recently when using the range finder, so the photographed objects can be larger than the original ones. However, the use of this trick has one limitation and two shortcomings. Limitation: it can only be used on cameras with weak macro ability, or on 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. After connecting the range finder, you may not be able to focus. For SLR cameras, because the focusing distance is relatively large, there is no need to care about this problem. Disadvantages: After the use of the range finder, 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 results of photometry in the camera. But in fact, the real aperture value should be the displayed aperture value multiplied by the multiple of the range finder: for example, after a lens is connected with a 2× range finder, 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 photometric 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 by slight shaking when you hold it, so it is best to use a tripod to ensure the clarity of the picture. The range finder is often not light, but a little heavy. Therefore, when it is connected to the camera, it is easy to be top-heavy, even if it is placed on a tripod, it can't be absolutely stable. When you press the shutter, the vibration will also cause the failure of shooting. It is best to take a selfie or shoot with a cable release. Minimize the vibration.

2. use a close-up lens: a close-up lens is actually a convex lens. 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 a single piece or in multiple pieces, which is very flexible. Advantages: The investment is not big, generally 2 ~ 3 yuan, so you can buy a set of three tablets. Flexible and flexible, the lens does not occupy as much volume as the range finder after all. Any combination of several pieces, high flexibility. When using a close-up lens, the aperture will not be reduced as when using a range finder, so it can be used more boldly than a range finder. The last lens of some wide-angle additional lenses can be detached and used as a close-up lens, so those who have wide-angle lenses and are sure to buy wide-angle lenses should pay attention. Oh, does your purchase come with 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 are solutions. First of all, if you want to install a filter, you must buy an adapter ring. Generally, the adapter ring has two choices: larger caliber and smaller caliber. At this time, we still use a larger caliber. If it is a DC or SLR with a filter thread in front of the lens, it is best to buy a larger adapter ring and use a larger close-up lens. A filter with a large aperture allows DC to use the central part of the filter to image, avoiding the parts with poor imaging quality at the corners, and obtaining better imaging. Secondly, when using a close-up lens, it is best to use the telephoto end of the camera, which also makes full use of the imaging in the middle part. Third, appropriately shrink the aperture, the aperture is small, and the edge of the lens is less, which can further improve the imaging quality. Combined with several measures, the degradation of imaging quality will not be too obvious

3. Invert the lens: This method has been mentioned by many people, that is, connect the lens of the SLR-usually using a 5mm header-to the front of the DC or SLR through the double-head. This method has the largest magnification and the best imaging quality. However, the double-head is relatively difficult to find, inconvenient to operate, poor in mobility, and also has the problem of top-heaviness. Generally speaking, excessive magnification is rarely used, so perhaps this is the most wonderful shooting method, but it is not the most practical.
