In photography and cinematography, a multiple exposure is the superimposition of two or moreexposures to create a single image, and double exposure has a corresponding meaning in respect of two images. The exposure values may or may not be identical to each other.
and i like to try to copy all the time
and here’s one of the ways you can do one yourself .
Shoot the sillhouette. Make it against a white sky or a white studio backdrop. When shooting outdoors, a low camera angle can help get a clean white background with no intruding clutter. Byrne recommends shooting about an hour before sunset on sunny days. You can line up the dimmer afternoon light behind your subject and, with proper exposure, produce no flare.
Find the background texture. Color helps, and so do line and complementary shapes. As with the silhouette, find a texture that can be captured on white, with a minimum of surrounding clutter.
Prepare your camera. When you’ve found the texture to place within the silhouetted figure, you’re ready to make the composite. Dig through your camera’s settings to find the multi-exposure mode. Select it and switch your camera to live view. Find and select the base silhouette on the memory card. It will be displayed on the LCD screen.
Line up the images. With the silhouette displayed on your camera’s LCD screen, aim your lens at the textured subject. The texture (i.e., leaves, trees, flowers, bark, or rocks) will appear within the black silhouette. Finesse the texture’s effect by adjusting the camera angle, zoom, and exposure settings. When the textured overlay complements and fits well within the silhouette, fire away. Your camera will automatically merge the two.
