The author set up a photographic trial in order to determine the practicality of using photography with parallel- and cross-polarized light alongside routine clinical photography, and the usefulness of the resultant images in comparison with conventional photographs. It was found that the technique added no more than 5 min to patient contact time, and that the attendant cost was minimal. Parallel-polarization has proved relatively valueless, but cross-polarization significantly enhanced the definition of pigmented lesions, and has considerable potential as a technique for documenting specific conditions, and as a teaching aid.
作者进行了一项摄影试验，以确定在常规临床摄影的同时使用平行偏振光和交叉偏振光摄影的实用性，以及所得图像与传统照片相比的有用性。结果发现，该技术使患者接触时间增加不超过5分钟，且附带成本极低。事实证明，平行偏振相对没有价值，但交叉偏振显著增强了色素沉着病变的清晰度，作为记录特定病情的技术和教学辅助手段具有相当大的潜力。
