Carl Zeiss Camera Lens Division 7 We can then recognize three important properties of MTF here which we should remember when reading MTF curves: 1. Small differences in higher MTF values are particularly significant at high object contrast levels. resolution figures for the contrast of 2. On the other hand, weak tonal
We have encountered the various graphical depictions of the MTF: as a function of the spatial frequency, of the image height or of the focusing. We showed you four different basic types of transfer functions in the chapter on Edge definition and image contrast (part I, p. 13-15).
