Light scattering in the eye is reviewed, and its influence on vision is discussed in some detail. Isotropic scattering and formation of halos around point sources are described with reference to theory and experiments. Artists usually take intraocularly scattered light into account when painting natural scenes. A method to achieve similar effects in photography by the use of diffraction filters in front of the camera lens is demonstrated. A number of photos that illustrate the effects of such filters are shown.
本文回顾了眼睛中的光散射，并详细讨论了其对视觉的影响。参照理论和实验描述了各向同性散射以及点光源周围光晕的形成。艺术家在绘制自然场景时通常会考虑眼内散射光。展示了一种通过在相机镜头前使用衍射滤光片在摄影中实现类似效果的方法。给出了一些说明此类滤光片效果的照片。
