There are two photos in the Samsung photo.

A, double exposure, that is, repeated exposure twice during shooting, so that the images overlap on the same frame of film or the same digital recording file.

Second, double exposure is divided into film double exposure and digital photography double exposure.

Third, the double exposure of film.

1. Turn on the camera multiple exposure switch/key and set it to double exposure appropriately;

2. Make multiple exposures with lens cover and other equipment, and make the first exposure;

3. Under the condition of no exposure, complete the power-on (electric shutter) or mechanical winding (mechanical shutter) of the shutter, adjust and complete the focusing and parameter setting of the second object, and then carry out the second exposure.

Fourth, the double exposure of digital photos.

1. Open double exposure in the menu, and set the related parameters of multiple exposure, with the exposure times set to 2, continuous shooting times and so on.

2. Aim at the first exposure object and make the first correct exposure;

3. Aim at the second exposure object and make the second exposure correctly.

Five, the principle of double exposure and matters needing attention

The concept of secondary exposure is image overlap, and the principle of secondary exposure is "the first exposure image is the clearest, and then it becomes thinner and thinner."

Double exposure under normal light conditions is mainly to grasp the picture arrangement, and to have a favorable picture combination instead of harmful picture overlap. Double exposure under special conditions, such as night scene, requires a tripod to fix the camera and lock the focus. Generally, the elements of point, line and surface are highly coincident, and the combination of light and shadow effects is pursued. When setting exposure parameters, it is best to use the measured value of exposure meter.
