All kinds of exposure effects of photos can only be achieved by ps, which can not be achieved by camera alone.

A variety of exposure effects of photos can be achieved through ps, and shooting with a camera can also be achieved. Multi-exposure is a technical method in photography, which uses two or more independent exposures and overlaps them to form a photo. You can use special settings to create double-exposure photos directly from a digital camera, or use Photoshop to achieve the same effect. The produced images usually have a fantastic feeling, and can also be used to shoot extraordinary creative effects. Common exposure effects can be divided into three types: overlap, ghost and afterimage. Multiple exposure shooting in the camera needs to be set in the menu. Different models of SLR will be different, but they are all similar. Enter the menu main menu, select the multiple exposure option in shooting menu 3, and press OK to enter. To create a double exposure photo, you need to take the first photo and then the second photo to create an overlay image. The first picture will be the main theme, and the second picture will be a support or supplement. The first image is a portrait of a person or an animal with light or the sun behind it. The second image can be a landscape, people, flowers or a textured background.
