Understanding Lens Flare: Why Modern Glass Creates Those Dreamy Light Artifacts
Understanding Lens Flare: Why Modern Glass Creates Those Dreamy Light Artifacts I’ve spent countless hours chasing that perfect lens flare in my photographs—sometimes intentionally, sometimes cursing it in the field. But I recently dove deep into the optical physics behind this phenomenon, and it completely changed how I approach flare in my post-processing workflow. The Uncoated Glass Problem Here’s what fascinated me: when light hits an uncoated glass-to-air surface, roughly 4% of that light bounces straight back.
