Water absorbs much of the light, so that only bright days should be used. The angle of the sun at noon is a little too much overhead to strike fully on the side of the fish, although this can be remedied and the speed much increased by the use of a reflecting mirror in addition to the direct sun. This sometimes makes a beautiful effect on a sil- very fish. Our photographs of Ptcrophyllum scalare, Osphromenus trichopterus and the Banded Sunfish were done in this way. When a black background is wanted, procure the darkest medium obtainable and construct a ledge above it, so that the sun cannot strike directly on it. The water should be as free from particles as possible, particularly when using a dark background. It is desirable to cover the camera with black velvet to prevent reflections in the aquarium. Some operators use flashlights, but to the writer nothing seems as good as direct sun. In photographing down through the top of an aquarium it is nec- essary to suspend a glass at the surface, so that the bottom of it is wet and the top dry. This obviates blurring caused by refraction due to ripples. Where clear waters prevail there is no doubt that fine photographs of the natural bottoms of the shallower bodies of water can be made through a glass-bottom aquarium, slightly submerged in the Fig. 227. Photographing Arrangement The distance between aquarium and background should be sufficient to prevent a shadow falling on background. The aquarium is raised so that the board below will be out of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectl
