In the world of motion graphics and visual effects, lighting is everything. While Adobe After Effects comes with a native "Glow" effect, many professionals quickly outgrow its limitations. The banding artifacts, the lack of control, and the unrealistic "washed-out" look often force creators to seek third-party solutions.
However, for students learning motion graphics or hobbyists posting to Instagram, the free alternatives (like FXAA) are fantastic.
Stay glowing, and keep creating.
