Normally we obtain such types of images when the object is between the light and camera, the light falls on the object and the resulting photograph is obtained in such a way that only shadow of the photo is obtained.
Here is one of the example
The Image was captured during the time of sunset at the point of Krishna Koyna Sangam , Karad a couple of months ago.
As sun was exactly behind the person, the camera was able to capture only the shadow of person and objects all around.
- You may need to change the settings as per the light in the environment.
- Tripod required/ camera should be stable
