Master two key points of secondary exposure shooting

Lead: Multiple exposure is the product of the film era. Through multiple exposures on the same negative, strange photos were obtained. 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 shoot a wonderful multi-exposure work.

Recommended camera for second exposure shooting: Canon EOS 5D Mark III.

The multiple exposure function of EOS 5D Mark III makes it easy for us to shoot multiple exposure works. This design is very user-friendly and can be set according to the requirements to achieve satisfactory results.

Point 1: Control the exposure to make the effect more obvious.

When shooting, I will expose and compose according to the expected picture feeling, such as the multiple exposure picture on the left walking on the road. When I shot a model with a sense of depth walking on this road, the shadow I shot was reflected on the road, so I immediately thought of combining these two pictures to realize an unreal and strange picture through multiple exposures.

Because these two pictures are operable, I can get the most satisfactory result after many experiments. First of all, I took the back of the model as the main body and the horizon in the lower third to get the first picture. Then I stood in the middle of the road with my own shadow as the main body and the horizon in the upper third, and took a second picture with my camera upside down, so that the horizons of the two pictures could be better connected. In order to make the two subjects in the picture relatively clear, average? Shooting mode.

Frequently asked questions about multiple exposure shooting.

Does it take a long time to find a suitable scene that can be superimposed when taking multiple exposures?

A: Because we can't find a suitable superimposed scene nearby after taking the first photo, we can't get good results without a suitable scene, so we will be more cautious when choosing superimposed scenes; This kind of film has an advantage, because the film can be exposed for the second time after a long time, and the digital camera must shoot in a short time, so I suggest trying different re-exposure effects when shooting for the first time, and don't be afraid of not shooting well. If you shoot a few more times, you will find a picture suitable for multiple exposures faster.

How long did you wait to find two pictures suitable for re-exposure?

A: The longest time 15 minutes. Unlike film, digital cameras can shoot at a long interval, but they need to find the next shot quickly. If you can't find it in a short time, the camera needs to be on all the time, which will consume a lot of power, which is also a disadvantage.

The above picture was taken at 15 minutes.

Point 2: Make a reasonable composition and create a beautiful picture.

The technology of multiple exposure is a way to realize ideas and a kind of creativity. Therefore, in today's advanced technology, it is technically possible for us to easily shoot works with multiple exposures, but it is very important to arrange the pictures creatively and consciously in consciousness, which is very important for obtaining a successful work. As shown on the right, in the picture arrangement of this multi-exposure image, I combine the small sunflowers with the city scenery in the sunset, because the sky in the city scene is relatively empty, and the sunflowers just fill this gap and overlap with the light of the sunset, making the sunflowers more vibrant.

Camera advantage

In the multiple exposure function of Canon EOS 5D Mark III, a variety of controls are designed, which can control the synthesis method mode, exposure times, saved image range and so on. For example, save the range of the source image, which allows us to keep the composite image as well as the material image, making shooting more flexible and convenient.

Reject clutter effect

At the beginning of multiple exposure technology, if there is no idea and plan, the content of shooting will easily become chaotic and affect the visual experience, so if you want to reject the chaotic picture, you must have a plan.

If you don't want chaos, you must have priorities. The expression of multiple exposures mainly expresses the subjective feelings of the photographer. Any picture needs priority to illustrate the problem. Therefore, when expressing your personal thoughts, remember to be clear, and don't let the picture be confused and lack of primary and secondary contrast; We should make the scene as simple as possible. Although multiple exposures are addition, the feeling of the picture still follows the subtraction law of photography. For example, the dead branches in the wrong picture, coupled with the road fence, make the whole picture look chaotic, with no distinction between primary and secondary; In the correct picture, I take the girl with open arms in the grass as the main body and the neat trunk as the foil. The picture has distinct layers, which can not only highlight the main body but also exert the charm of multiple exposures and create a strange picture.

It is still important to pay attention to post-adjustment

Before adjustment

After adjustment

Generally, I will adjust the contrast and color in the later stage of multiple exposure effect to strengthen the content that needs to be highlighted and increase the picture effect. The picture below shows the combination of people and flowers. At this time, when adjusting the contrast, be careful not to let the saturation of the dark part be too high and lose the hierarchy, while the bright part will turn gray because of superposition, so don't adjust it to overexposure.
