What is a second exposure? Brief introduction of secondary exposure.

1, double exposure refers to multiple exposures on the same negative, which is a skill that many people must play when touching the camera. That kind of mysterious and ineffable visual effect often makes people indulge in it. Nowadays, middle and high-end automatic cameras have multiple exposure functions, and you can set multiple exposures by using the function settings.

2. As early as the film SLR era, many photographers and photographers superimposed two or more light negatives through double exposure to achieve the purpose of increasing the illusory effect of the picture. After entering the digital age, it is easier to achieve double exposure.

3. Now you can import the pictures into the computer, and then use the image processing software to superimpose the pictures, so as to achieve the effect of double exposure. Moreover, when overlapping, the pictures can be enlarged or reduced locally, which greatly increases the convenience of double exposure.
