Light effects refer to the various ways light interacts with objects and environments, creating visual phenomena. These effects can include reflections, refractions, and shadows, which occur when light bounces off surfaces, bends through materials, or is blocked by objects. Understanding these interactions helps in fields like photography, art, and design. Different light sources, such as the Sun, LEDs, or candles, produce unique effects based on their intensity, color, and angle. For example, sunlight can create vibrant colors during a sunset, while artificial lights can cast dramatic shadows in a room. These variations influence how we perceive our surroundings.
