The knowledge of paint pigments' optical characteristics enables the selection of an appropriate imaging methodology for non-invasice artwork investigation. i. e. optimising the visibility of preparatory layers using conventional photographic cameras modified for data acquisition in the near infrared wavelength range. This contribution deals with the limits of this simple method in the analysis of selected common pigments used in prepared canvas mock-ups with typical structure including ground layer and underdrawings of various compositions.
