The application of photogrammetry to the measurement of skin friction using oil-film interferometry is discussed. Oil-film interferometry and photogrammetry are first described to justify the need for photogrammetry; and then the method is applied to two flows. The results indicate that when model curvature is high or the camera-to-model distance is short; large uncertainties (of the order of 10% ) in skin friction can be introduced if photogrammetry is not applied. For most applications demanding high-accuracy skin-friction measurements; approaches such as those described in this article should be considered;
