Soft focus is a photography and cinematography technique that creates a dreamy, blurred effect in images. This effect is achieved by using special lenses or filters that slightly diffuse the light entering the camera, softening the details and reducing sharpness. The result is a more flattering and ethereal appearance, often used in portrait photography to enhance the subject's features. In addition to photography, soft focus is also utilized in film to evoke a romantic or nostalgic mood. This technique can help to create a sense of intimacy, making it popular in genres like romantic films and music videos.
