Multi-exposure Advanced Course: 12 Post-exposure Overlay Analysis

Posted by Adminluckinartist on

Multiple exposures are a technique in photography that uses two or more independent exposures and then overlaps them to form a single photograph. Because the parameters of each exposure are different, the final photo will produce a unique visual effect. Multiple exposure is a photographic technique, but in order to set off the atmosphere, it is often chosen to use different focal lengths for two or more exposures to express the content that a photograph is difficult to express. The technique of multiple exposure has its own charm. Taking double or multiple images is full of magical artistic effects. There are many concrete combinations of multiple exposures, each of which has infinite creative space. Following are 12 photos of Pang Yi to focus on the analysis of 12 forms of multiple exposure. In the era of traditional cameras, re-exposure is very far away from us. Now the digital age makes it very convenient for this gorgeous photography technology. We can easily get multiple exposure pictures by taking multiple photos in the early stage and adding PS. But do we know why we choose multiple exposure? Although multiple exposures can achieve dazzling results, it does not mean that it can be exposed indiscriminately. It has the author's consideration and anticipation of the subject matter and content, focusing on "blank space".

1. Reexposure of a single character duplicated into multiple people

Fixed position and background unchanged, let the same person take multiple photos in different positions with different postures, and then synthesize by matting. It's the simplest reexposure. There are only two models in the shooting of Dreamback Girls Hall, but many people can be reproduced through re-exposure. The increase of scenes and numbers can make the picture more atmospheric.

2. Re-exposure of Fixed Location of the Same Person

Fixed seats and background remain unchanged, unlike the Girls'Hall, the characters are not copied into many people, but on some specific elements, through multiple overlays, each object in the picture can present the most perfect side. The different postures of the flying white paper and the white cat in "Youth Fantasy" are the effects of re-exposure.

3. Re-exposure of Portraits and Buildings

This way of superimposing characters is as small as possible, the purpose is to integrate with the scenery. This way is especially suitable for buildings with complex structures. The more complex the building structure is, the more obvious the strange effect of the Inception Space will be. The staircase of Shanghai 1933 old factory is stitched together with photographs, which makes the picture have a wonderful sense of fragmentation, leaving white space in the middle and creating a special space in the chaos. Above is a girl standing on the stairs, below is a boy, forming a corresponding, making the seemingly messy picture, with a balance point.

4. Re-exposure of portraits and scenery features

The technique of multiple exposure is a way of expressing ideas. In shooting, we should observe the environment more and arrange the pictures consciously. Because after the first shot, there is often no suitable overlay scene in the vicinity, and no suitable scene can not produce good results, so the choice of overlay scene should be cautious. If this product is exposed twice with the bus stop sign, in the near superposition, the same object can be photographed by using the changes of focal section, angle and aperture size, which can achieve good results.

5. Re-exposure of different focal segments of portraits

The difficulty of multiple exposures is that the overlapping elements should not destroy each other and interfere with each other, but should complement each other and expand each other. The effect of multiple exposures is not the sum of multiple elements, but the product of multiple elements. The superposition of portraits between facial close-ups and full-body photographs can also have a good effect. Usually, the light and shade of the shadows are the best way to superimpose, while the superposition of characters is often in large shadows and black hair is the suitable area for superimposition.

6. Re-exposure of False and Real Nightscapes

The virtual and real exposure of night scene is relatively simple, for the same night scene to take two photos, the real scene to take the night scene, focusing on details; the virtual scene to take out of focus neon lights, focusing on creating a dreamy atmosphere.

Re-exposure of scenery and still life

Playing with multiple exposures is mainly to have a fun heart, not too strict, because the effect of multiple exposures often has a certain distance from the expected, this time can take such an effect, the next time in the same way, not necessarily be able to take it again. Through multiple exposures, arbitrary objects can be superimposed beyond time and space, and many unique, pleasant or far-reaching artistic effects can be achieved. Sometimes the effect can only be known at the moment of superimposition, and the joy of this divine pen is also the pleasure of re-exposing. The picture in the picture is a re-exposure of a crab in a mineral water bottle and the prospect of a sea bath taken at the Qingdao Sea Bath. Overlapping together, there is a wonderful feeling of "a cup of sea".

8. Re-exposure of Capturing Animals in Different Poses

It is difficult to capture the animal's posture when taking pictures of scenery, and superposition of different animal postures by re-exposure can bring strong visual impact, because it is difficult to control and judge the animal's trajectory and direction in a single shot, but re-exposure can solve this problem. In this case, the superposition effect is particularly obvious in the capture of bird posture.

Re-exposure of buildings and animals

Re-exposure of buildings and animals or people can often bring a strong contrast, because buildings are dense forests of reinforced concrete, representing the city and order, and people or animals represent freedom and warmth. When expressing your personal thoughts, remember to have a clear idea. Don't let the pictures be disorderly and lack of primary and secondary contrast. When choosing scenes, we should try to be as simple as possible. Although multiple exposures are made by adding method, the feeling of the picture still follows the rule of subtraction of photography. The re-exposure of Manhattan's tall buildings and flying white pigeons in New York highlights the characteristics of New York very acutely. One picture is better than thousands of words.

10. Re-exposure of the same building from different angles

Building structure is complex, it will be more difficult to overlay. In the process of overlay, we need to find common points of different angles. If we encounter the situation of overlay disorder, we should also make appropriate selection and feathering erasure for each overlay layer according to the situation to remove the interference factors, so as to achieve the picture. There is order in disorder. When the technique of multiple exposures was first started shooting, if there was no idea and plan, the content would easily become chaotic, affecting the visual perception. If you want to reject the chaotic pictures, you need to have a plan. If well planned, extraordinary results will be achieved, especially in the gorgeous interior of the church.

11. Constructing the Prospect of Portraits by Re-exposure

Prospects in portraits are very important, but in actual shooting, we often can not find the right prospects to take the depth of the portrait. At this time, the way of re-exposure can be used to build the prospects. Select some scenery pictures which have been taken by PS and re-expose them on the unpredictable portrait photos in the later stage. After setting up the superposition mode, the superimposed layer is blurred by the lens with the post-filter, which can achieve the effect of false and true. In the foreground illustration section, the flowers next to the model are superimposed and blurred after taking close-ups. Did you find that?

12. Adding glare by re-exposure

Film machines shoot in leaky conditions, sometimes a moderate leak of light will bring a beautiful glare effect, which can also be re-exposed for later simulation. In the picture of the old Beijing city wall, after taking the full view, I took some close-ups of tree shadows overlapped in the lower left corner of the photo. In fact, it is not glare, but the effect of simulated glare with double exposure. In order to fuse the nature, if the effect of multiple exposure is normal, it can also adjust the contrast and color in the later period, which can strengthen the outstanding content and increase the effect of the picture. When adjusting contrast, special attention should be paid not to make the dark part saturated too high and lose the layers, while the bright part will gray because of overlapping, so don't overexpose.
