What describes the characteristic of diffused light when it illuminates a subject?

1. From a single source

2. From multiple directions

3. From a reflected surface

4. From overhead only

The correct answer is: From multiple directions

The characteristic of diffused light is best described as coming from multiple directions. This is because diffused light scatters, softening the shadows and reducing contrast on the subject. When light is diffused, it generally does not come from a single point. Instead, the light rays are spread out over a larger area, which creates a gentle illumination effect. Diffused light is typically produced through methods such as utilizing softboxes, sheer curtains, or other materials that allow for light to pass through but spread it out. This property is what makes diffused light very flattering for photographing subjects, as it helps to minimize harsh shadows and creates a more even light across the subject's features. In contrast, light from a single source would create more defined shadows and highlights, while light reflecting off surfaces may introduce color casts and uneven lighting. Overhead light can also produce distinct shadows, but it doesn't inherently carry the characteristic of diffusion without any further softening techniques applied. Thus, the essence of diffused light clearly aligns with illumination from multiple directions.
