Under adverse optical conditions (turbidity of the media) a well-trained observer/artist, using slit-lamp stereomicroscopy, is able to display in a drawing considerably more correct information about a fundus than what a fundus camera records. To a lesser degree this holds under favorable conditions too. General advocation of photography for being more objective is questioned; even if true, meme objectivity, i.e. no false information, would not make up for loss of important details. This paper intends to prove these points experimentally on an object (a nummulite shell) unfamiliar to the artist charged to do the drawing. The latter and photographs taken under varying conditions were compared inter se and with a high resolution scanning electron micrograph.
在不利的光学条件下（介质浑浊），训练有素的观察者/艺术家使用裂隙灯立体显微镜，能够在绘图中展现出比眼底相机记录的关于眼底的信息更准确得多的内容。在有利条件下，这种情况也在一定程度上成立。对于摄影因更客观而受到的普遍推崇受到质疑；即使这是真的，即没有虚假信息，但缺乏重要细节这一点也无法弥补。本文旨在在一个对于负责绘图的艺术家来说不熟悉的物体（一个钱币状贝壳）上通过实验证明这些观点。将绘图与在不同条件下拍摄的照片相互比较，并与高分辨率扫描电子显微镜照片进行比较。
