This article explains the difference between barrel distortion and pincushion distortion in anamorphic lenses — how each one bends straight lines, what causes them, and how they affect the image. Barrel distortion, where lines bow outward, is what gives certain anamorphic lenses their distinctive look, pulling attention toward the center of the frame. That quality is what makes some lenses feel cinematic in a way that’s hard to replicate digitally. The article also covers related optical characteristics like focus breathing, field curvature, and anamorphic mumps, and explains which distortions can be corrected in post and which can’t. Worth reading if you want to understand why some lenses have more character than others, and what you’re actually seeing when a shot feels unmistakably anamorphic.
This piece is something that caught my attention, so I thought I’d capture it as a tidbit. The Claude synopsis above may have an errant AI hallucination or two. Please support the original author(s) and visit their site for the whole story and accurate information:
