What Negative Visual Effect Is Caused By Curvature Of Field Cresting?
What Negative Visual Effect Is Caused By Curvature Of Field Cresting? This is typically called “pincushion distortion“. Negative distortion decreases the magnification with the most distant points being the most affected. This is called “barrel distortion”. What is field curvature in a lens? Field Curvature, also known as “curvature of field” or “Petzval field curvature”,
