[Method] Firstly, the photographic mode of a common digital camera was set as ＂macro＂ （or ＂soft snap＂ ） and ＂flash off＂. Secondly, the small flower or fruit was magnified with a magnifying glass, and then the magnified flower or fruit was automatically focused with the digital camera lens. After automatic focusing, the shutter button was pressed and the photograph finished. [Result] With this method, the clear inflo- rescence or floral photographs of Eragrostis pilosa （ Gramineae ） , Bidens biternata （Compositae） and Tribulus terrester （Zygophllaceae） were obtained in field. [ Conclusion] The optical system of a digital camera has been changed by the magnifying glass, which improves the photographic function of a common digital camera to small flowers and fruits, and also easily gets their clear photographs.展开更多
