Introduction of macro shooting skills

1, macro mode. At present, all digital cameras on the market have macro shooting function, which is relatively easy to use. However, when using macro mode, it must be noted that when the distance between the camera and the object is less than 20cm, it is best to use LCD to view the scene instead of optical viewfinder, because there is little difference between the optical viewfinder and the range captured by the lens when shooting the distant view, but when using macro mode, the gap is large. In addition, macro photography will make the shutter speed very slow, and using autofocus function is even slower than manual operation. In order to generate perfect macro images, some digital cameras are equipped with self-timer, which can effectively prevent camera shake.

2. Choice of focus. Different focus choices can produce different image effects. When moving the focus, the subject should be in the middle of the picture. In general, you should choose the most attractive part of the picture, that is, the part you want to show most, and keep the shutter half pressed. After focusing (wait a moment for the camera to focus), press the shutter calmly to avoid weakening the photo. Generally speaking, in the macro mode of digital camera, the closer the lens is to the object, the bigger the object will be. If you don't pay attention to the finishing touch, the picture will look very dull. For example, when shooting a subject like a small insect, the choice of focus should fall on the insect's eyes. Eyes are the aura of life, the clearer you shoot, the better. Especially tiny creatures like bees, caterpillars, ants and insects, we should pay more attention to the expression of our eyes.

3. Focus and depth of field. Depth of field is often the key to the success of macro photography Because the lens is very close to the scene during macro shooting, the depth of field is generally shallow and the background is almost invisible. But sometimes in order to emphasize the picture effect, it is necessary to strengthen the depth of field appropriately, so special attention should be paid to the adjustment of focal length and depth of field. Depth of field generally depends on three factors: aperture size. Under the condition of constant focal length, the larger the aperture, the shallower the depth of field, and the smaller the aperture, the deeper the depth of field. In order to show the details of flowers, birds, fish and insects, and to increase the clarity of the subject in the vertical direction, it is generally suitable to use a larger aperture value to deepen the depth of field. The distance between the lens and the scene. The farther the distance, the deeper the depth of field, and the closer the distance, the shallower the depth of field. When shooting, it is best to put all the objects to be shot in the same plane perpendicular to the lens axis, otherwise some objects may not be sharp enough. If possible, you can configure a wide-angle lens, which will not only increase the depth of field, but also bring you closer to the scene. The greater the focal length, the shallower the depth of field, the smaller the focal length and the deeper the depth of field. Different combinations of aperture and focal length can produce different depth of field. Learn to use the combination of aperture and focal length reasonably, which can not only blur the background, but also ensure the clarity of the subject. If you take macro shots with remote zoom, the photos you take will not be ideal.

4. Exposure and background. The exposure procedure of macro photography is slightly different from that of ordinary photography, because the objects shot at macro are generally small, occupying only a small part of space, and the exposure procedure is likely to be fooled by the background, so it is best to add the background manually when shooting, which can make the theme stand out.

5. Add background. Generally, neutral gray paper can be selected as the background. On the one hand, using gray can make the exposure more accurate, on the other hand, using gray can make the background look bright. This color can go with ordinary colors. You can also use white or black background, but pay special attention to it, because they can easily lead to inaccurate exposure, resulting in overexposure or underexposure. At this time, it is necessary to use exposure compensation to adjust. If the background is too dark, increase the exposure; if it is too bright, decrease the exposure.
