A line or curve that connects points in an image or chart that have the same level of brightness or light intensity.
The isophote on the graph showed areas of equal light intensity, helping to analyze the lighting conditions.
Isophote is formed from "iso-" (meaning equal) and "phōtē" (from Greek "phōs", meaning light). The term refers to lines or areas that have equal light intensity, thus combining the meanings of equal and light.
Think of 'equal' ('iso-') light intensity when you hear 'isophote' — it describes areas that share the same level of light.
