Advancements in digital cameras and the advent of smartphones have magnified the importance of clinical photography in facial plastic surgery. Here, we aim to examine the effect of different camera types, focal lengths, and distances from subjects on facial distortion.
Twelve subjects underwent a series of frontal photographs using a smartphone camera and a full-frame digital single-lens reflex camera. Photos were captured at six distances from the subject. Seven focal lengths were used at each distance for the full-frame camera. Measurements of facial landmarks were made for each photo, with those made at 60 inches using the full-frame camera considered the gold standard and used for comparison.
Distortion of facial features using the full-frame camera occurred when photos were captured 8 inches away using short focal lengths. A 12%-19% increase in vertical stretching of the midface occurred when using focal lengths of 24, 35, and 50 mm (p < 0.05 for all). The same features were distorted when a smartphone camera was used at 8 inches (18% increase, p < 0.01) and 12 inches (12% increase, p < 0.03).
Distortion of midfacial features using both smartphones and full-frame cameras occurs with short, 'selfie' distances between the camera and subject.

数码相机的进步和智能手机的出现，凸显了临床摄影在面部整形手术中的重要性。在此，我们旨在研究不同相机类型、焦距以及相机与拍摄对象的距离对面部变形的影响。
12名受试者分别使用智能手机相机和全画幅数码单反相机拍摄了一系列正面照片。在距离受试者6个不同的位置拍摄照片。全画幅相机在每个位置使用7种焦距进行拍摄。对每张照片中的面部标志点进行测量，以全画幅相机在60英寸处拍摄的照片作为金标准并用于比较。
使用全画幅相机时，当在8英寸距离使用短焦距拍摄照片时，面部特征会出现变形。使用24、35和50毫米焦距拍摄时，中面部垂直拉伸增加了12% - 19%（所有p值均<0.05）。当在8英寸（增加18%，p<0.01）和12英寸（增加12%，p<0.03）距离使用智能手机相机时，相同的面部特征也会变形。
相机与拍摄对象之间距离较短（即“自拍”距离）时，使用智能手机和全画幅相机都会导致中面部特征变形。
