Al- though it has too often lieen employed to give an air of thoroughness to work of no ecological value, it is as important for recording the structure of vegetation as the automatic instrument is for the study of the habitat. No ecologist is equipped for systematic field investigation until he is pro- vided with a good camera and has become skilful in its use. For this reason, it is felt that a few hints concerning photographic methods and their appli- cation in ecology may not be out of place. No written advice can take the place of experience, but certain elementary suggestions and cautions will greatly shorten the apprenticeship of one who does not have the good for- tune to be taught by a professional photographer. To the student of ecology, the camera is not a toy. It must be understood and operated with as much thoroughness as any other instrument, and when this is done, the results will be equally certain and Fig. 56. 4x5 long focus "Korona" camera (series V)* 236. The camera and its accessories. Although two cameras are desir- able whenever it is possible to obtain them, a single one will meet all the requirements of field work. This should be 4 x 5 inches in size, since it is much more convenient and will do all the work that a larger camera can. In the comparatively few cases in which larger views are needed, the 4x5 negatives can be readily enlarged. The smaller instrument is less expensive in operation because of the cheapness of the plates, and it gives a negative of the proper size for lantern slides and for reproduction. A 6yi x 8)^ camera is valuable in special cases, such as making a series of photographs for maps. In the writer's own experience, the 6j^ x 8j4 camera, although used exclvisively at first, has been almost completely supplanted by the 4x5. The best field camera is of the f
