Many successfulphotographs of insectshave been taken byprofessional entomolo-gists in insectaries thatpractically are simplyglass houses, withstrong light comingfrom all directions. Insuch situations theexposures are veryshort, and it is com-paratively easy to getpictures of insects inall stages. The lighteffects, however, areusually flat, and thedetails of structure arefrequently lacking. Igreatly prefer a verydifferent sort of a studio, and have taken most of mypictures in a basement room lighted only from one sideby comparatively small windows, so curtained that thelight is easily controlled. This, of course, involves longerexposures, which in turn give greater detail and muchmore satisfactory results. One great advantage of the 109. Fig. 103. — Larva of the Polyphemus Moth. Nature Biographies. side windows is that the Hght effects are rounded ratherthan flat, so that the form of the insect or plant is moredistinctly brought out. There is also a decided advantage in utilizing a base-ment room, or, at least, one near the ground, especially in a building in whichthere are other occu-pants. The slight-est movement of thespecimens before thecamera spoils thepicture, and I havefound that even onthe second floor ofa solid brick build-ing the slammino- ofa door often causedsuch a jar as to setthe leaves of a plantin motion. Underthe most favourableconditions there arealways enoughchances of failure,so that one does notcare to run thisadditional length of exposure will depend, of course, directlyupon the light at the time.
