How does Canon 750D camera take a second exposure image?

1 and Canon 750D are entry-level models of Canon, and there is no multiple exposure function. Only Canon SLR with mid-range and above models can configure this function.

2. It can be completed by post-image processing software, and photoshop software is recommended.

3. If you want to take a second exposure shot, it is recommended to choose Canon EOS 70D. When taking second exposure shooting with Canon EOS 70D, first set the mode dial of the camera to any creative shooting mode; Then press the menu key, find the multiple exposure setting bar, select it and open it; Multiple exposure control options: average. Because it is a double exposure shooting, after entering the setting page, set the exposure times to twice, and then click Set to confirm. Settings. Next, you can set the parameters such as aperture, shutter and ISO according to the basic steps of camera shooting, and then choose the appropriate scene to shoot. Take two different photos in succession, and the camera will automatically combine them into one photo. In this way, the gorgeous double exposure work is completed and the light is well controlled. It is the key to imaging effect.

Extended data:

1, "Photography is the art of using light" is very accurate. Photography, or taking pictures, is nothing more than holding a camera. When you press the shutter button, the shutter (the door between the world outside the lens and the photosensitive element inside the fuselage) will open and close later. In this short time, light will come in from the lens and shine on the rectangular photosensitive element, and tens of millions of photosensitive points on the photosensitive element will record the color of the light shining on it.

2. Suppose a dark and closed room with a small round window on one wall and a photosensitive material (white asphalt, large film or CCD/CMOS) installed on the inner wall opposite to the window. This is a big room camera. The room was dark before the small window was opened. When we open the small window, the light enters through the small hole and hits the film on the opposite wall, resulting in photochemical reaction (or photoelectric reaction, if it is CCD/CMOS), and the photo is born. This process is called exposure. In order to get correctly exposed photos, the exposure must be accurately determined. The so-called exposure is how much light is allowed to enter this closed room. If there is too much light, the photos will shine, and the night will become the day. If the amount of light is too small, the photo will turn black and white will turn black. ?

3. Exposure is a combination of aperture, shutter and sensitivity ISO. Exposure, that is, the computer uses natural light source mode, which is usually divided into manual exposure, AE lock and other modes. The quality of the photo is related to the exposure, that is to say, how much light is needed to make the CCD get a clear image. Exposure is determined by light passing time (shutter speed) and light passing area (aperture size).

4. Camera and equipment with shutter: By opening the shutter, images of people, scenes and objects are exposed to silver salt film by different bright and dark light, resulting in latent images.
