Examples: Field Curvature and Color Fringing (SUV)

This image is a simple one, yet serves to illustrate both field curvature as well as color aberrations and sharpness across the field. Image made on the Canon 5D Mark III.

Field curvature analysis

The entire frame is shown further below under the color fringing analysis.
