Pohlia lutescens (Limpr.) Lindb. F. in Britain and Ireland

Abstract

Background, reference, and instructional information is provided to enable the best possible photographic recording of mosses and similar plants, using equipment that is generally available from High Street outlets; specialist techniques rely more on improvisation than on specialist equipment. About half of the paper consists of straight forward instructions and hints for photography ranging from habitat shots to extreme macro, and dealing with special categories including luminous mosses, time sequence, and capsules. A step-by-step basic example of procedure is provided for a simple macro setup for field work. The paper presumes a basic photographic understanding, but elaborates on those aspects that are particularly relevant to moss photography. Sections deal with determining image magnification, and recording procedures. A close-up flash calculator dial (original) is provided, with instructions to help with flash exposure for all natural history work. Also an appendix of relevant formulas (some original) is provided, as are graphs (both original) for depth of field and resolution at all apertures and magnifications up to × 10, for all subjects.
