Ορισμός και Σημασία του "lens flare"

What is a "lens flare"?

A lens flare is a visual effect that occurs when bright light, such as sunlight or artificial light, enters the camera lens and scatters inside it, creating streaks, rings, or spots of light in the image. This effect can happen naturally when the camera is pointed towards a strong light source, or it can be added intentionally in post-production to create a sense of realism, drama, or visual interest. Lens flares are often used in film and photography to enhance the atmosphere, convey intensity, or add a stylistic touch to a scene.
