How can I take shadow pictures in my room?

To take shadow pictures in your room, you can use a strong light source, such as a lamp or flashlight, to create shadows on a blank wall or surface. Position objects or your hands between the light source and the wall to create interesting shadow shapes. Adjust the distance and angle of the light to control the size and sharpness of the shadows. Experiment with different objects and lighting setups to create unique and artistic shadow pictures.
