How to take wonderful multiple exposure photos?

Lead: Do you often marvel at some fantastic multiple exposure photos? Do you also want to try to take such beautiful multi-exposure photos? Do you want to know the shooting skills behind this multiple exposure photo? Then let's get close to multiple exposures and learn about the skills of multiple exposures.

Multiple exposure is a shooting technique and a product of the film era. Through multiple exposures on the same negative, a strange picture was obtained. In order to set off the atmosphere, this technique is often chosen, and two or more exposures with different focal lengths are used to express the contents that are difficult to express in a photo. Multiple exposure technology is generally used to take two or more photos. The principle of multiple exposure technology is to shoot multiple images on one film, so that an object can appear in the picture many times, and it can shoot magical effects out of nothing. This is its unique charm and attracts many people to use this technology. In traditional film SLR cameras, multiple exposure is a very important function and a unique photography technology. In the digital age, many cameras have also designed multiple exposure functions, which provide good conditions for everyone to easily shoot multiple exposure works. Let's take a look at how to make a wonderful multi-exposure work.

First of all, pay attention to the two exposures before and after, pay attention to the echo and cooperation of composition, highlight the theme, that is, decide your protagonist and supporting role. To put it simply, clean pictures should be selected for the first shot, and more complicated pictures should be exposed for the second time as embellishment. Because the theme of the photo is too messy, avoid re-exposure. The effect is not good.

The technique of multiple exposures is simply multiple exposures, that is, multiple exposures in the same place and the same scene. In the process of taking pictures, the camera and the object are kept still, and multiple exposures to the object at different times or under different lighting conditions can highlight the layering of the object. The same scene and different scenes have various exposure methods, such as real focus and real focus, virtual focus and real focus, and the size and size of the image. Through these exposure methods, different scene contrast and scene repetition effects can be produced. This is one of the most basic multiple exposure techniques, which is more suitable for shooting night scenes.

Another way is to change the focal length of multiple exposures, which refers to the multiple exposures of all real-focus lenses and the combination of virtual and real-focus lenses when shooting the same scene or different scenes. For the shooting of flowers or still life, the method of changing the focal length can be used to shoot twice, once with real focus and once with virtual focus. In the process of real focus shooting, you can expose more, and in virtual focus shooting, you can expose less. Every shot is a multi-exposure image of real focus and virtual focus, and there are often multiple exposures where the subject with the same focal length is displaced, multiple exposures where the subject with variable focal length is in situ, and multiple exposures where the subject changes in the middle of shooting.

Thick and thin multiple exposures are similar to virtual and real multiple exposures. When shooting, all subjects can be exposed to real focus for many times, and subjects can also be exposed to virtual focus and real focus for many times. However, in multiple exposures, exposure compensation should be adopted to make the images with multiple exposures have different brightness. The multiple exposure of changing the focal length of the lens for many times refers to the multiple exposure of changing the focal length or shooting distance of the lens when shooting the subject, and then taking the next shot. When zooming, you can change the position of the subject or move the camera, or keep the position of the camera and the subject unchanged.

There is also a method of multiple exposures, which is the shielding method. The so-called occlusion method is to capture the subject once by blocking half of the lens, and then capture the subject in different positions once by blocking the other half of the lens, so that the subject can be exposed to the negative at the same time.

There is also a multiple exposure technology, that is, the multiple exposure of superposition method. In some areas of the picture, positions are reserved in advance, and multiple exposures are carried out in the reserved areas, which can also form a very expressive effect. During shooting, the position of the camera can be fixed or moved. Here, we use a fixed camera position to take multiple photos of a person in multiple positions and then synthesize them together.

Finally, the digital darkroom uses image processing software for post-production of multiple exposures. With the help of computer, this paper uses the image processing software in digital darkroom to superimpose one or more images taken in the early stage on one picture, thus forming the effect of multiple exposures. The post-production and synthesis of multi-exposure images by using image processing software can be adjusted and modified at will, but it is time-consuming and laborious, so it is not as convenient as shooting multi-exposure images directly with a camera.

The most striking highlight of Canon 1-DX camera is the new multi-exposure shooting function. The previous SLR cameras only overlapped multiple images, and these new cameras made the cameraman more comfortable to operate. This means that in the Olympic Games, the cameraman completed incredible high-speed multiple exposure shooting at the speed of 14 frames per second, capturing the wonderful moments of the athletes.

EOS 5D Mark III multiple exposure function has four modes, and the number of multiple exposures can be 2-9 times. There are four image overlapping modes: superposition, average, bright and dark. Among them,? Addition? Mode is like a film camera. In this process, multiple images are simply superimposed without exposure control, so the synthesized photos are brighter than those before synthesis, which means that the exposure will increase. ? General? This mode controls the brightness of photos while synthesizing, automatically compensates the negative exposure according to the number of photos taken by multiple exposures, that is, reduces the exposure, and finally adjusts the synthesized photos to the appropriate exposure. Sure, choice? Addition? Or? General? In these two modes, the synthetic effect of soft focus can be obtained by changing the focus position. Besides? Bright? And then what? Darkness? These two modes are to synthesize only bright or dark parts after comparing the basic image with the image synthesized on it. These two modes are suitable for use when you want to emphasize the outline of the subject.

From these four modes, it can be seen that the synthetic image either increases the exposure, or adds image elements on the basis of appropriate exposure, or makes a fuss about highlights or dark parts, all of which increase the information content of the picture. This includes the details of dark and bright parts, the increase of color, the increase of contrast and the increase of elements in the picture. , increased the amount of information for the photos after multiple exposures, and the pictures became bigger and bigger.
