A collage is a creative composition that combines various materials-such as paper, photographs, fabric, or other objects-attached to a backing surface alongside original artwork. In photography and mixed-media art, collages allow artists to blend textures, images, and artistic elements to produce visually dynamic and expressive pieces. This technique is widely used for artistic experimentation, storytelling, and visual communication, offering photographers and artists a versatile way to explore composition, layering, and creative expression.
