Slit lamp photography: The basics

This introductory paper is designed to explain the basics of slit lamp photography with the use of illustrations and sample images. The two primary methods of illumination are described with reference to positioning and magnification, as well as the use of background illumination. Filters and dye usage are described along with a brief explanation of associated imaging techniques. Further explanation of techniques will be looked at in subsequent articles, this paper aims to give an over view rather than an in-depth discussion of techniques.
