A method has been developed to detect underdrawings in paintings more completely than is possible with ir photography. A modified Barnes ir camera has been used equipped with a lead sulfide detector. The results can be explained in terms of an increase in hiding thickness of paint layers with the wavelength. Practical aspects of reflectography of paintings are briefly described and an example is given.
已开发出一种比红外摄影更能全面检测绘画底稿的方法。使用了一台配备硫化铅探测器的改进型巴恩斯红外相机。结果可以用随着波长增加颜料层遮盖厚度来解释。简要描述了绘画反射成像的实际情况并给出了一个例子。
