The … WebJun 19, 2006 · MTF measures image spatial frequency. It is similar to the graphic equalizer on your stereo in that it represents the response of your stereo to different frequencies. In the visual realm, MTF tells you how much high-, mid- and low-frequency you can record. MTF numbers always start high, then drop, as imaged objects become more fine.
