How to take multiple exposures in wedding photography?

Multiple exposure is to expose the same negative multiple times and get a strange picture. 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 content that is difficult to express in a photo.

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. It is necessary to avoid the bad effect of re-exposure because the theme of the photo is too messy.

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, we can take two shots by changing the focal length, 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.
