Zusammenfassung:	Method for determining, in a natural posture, at least one geometric/physiognomic parameter associated with the mounting of an ophthalmic lens in a spectacle frame intended to be worn by a wearer. The method includes: (a) capturing at least one substantially frontal image of the wearer's head; (b) determining a measured value of an angle of inclination during the capturing step, which depends on the inclination of the wearer's head about a main axis perpendicular to a sagittal plane of the wearer's head; (c) determining a reference value of the angle of inclination corresponding to a natural posture of the wearer's head; and (d) determining the required geometric/physiognomic parameter on the basis of the substantially frontal image captured and as a function of the difference between the measured value of the angle of inclination determined in step (b) and the reference value of the angle of inclination determined in step (c).
