Introduction. The paper considers the possibility of using regression equations to compare data obtained by direct measurement of a person in the field and measurements made from anthropological photographs. Materials and methods. Three samples were analyzed – the population of central Chile (175 men and 55 women), the indigenous population of Altai (38 men and 67 women) and the Russians of Altai (52 men and 42 women). The collection of material took place in two stages: working directly with the subject and working with photographs. Measurements of the parameters of the head and face of the subjects in the field in both cases were carried out according to the classical method of V.V. Bunak, adopted in the Russian anthropometric school. Photographing in portrait and in profile was carried out taking into account the recommendations for the production of anthropological photographs. Further, the dimensions in pixels were calculated from the photographs, and converted into mm using one indicator, which was measured both in the field and from a photograph (the distance between the canines for the Chilean sample, and the width of the nose for the Altai ones). Results and discussion. The sizes obtained in the field were compared with their counterparts obtained from photographs. For these dimensions, regression equations were obtained, allowing to most accurately translate the dimensions obtained from photographs into real dimensions. It was found that in the event that the thickness of soft tissues above the bone base is insignificant or the size does not depend on the bone base, the difference in measurements on the subject and in the photograph is within the boundaries of acceptable discrepancies between researchers. In this case, the performance of the equations will depend on the scale of the element used for recalculation – the larger it is, the smaller the error. Regression equations were obtained on three samples, allowing one to compare the linear dimensions obtained in the analysis of photographic images with the dimensions obtained in the field. However, it should be emphasized that only the mean values obtained using the regression equations should be used, since in this way individual variability is leveled.
