FISH PHOTOGRAPHY AT HOME - tor 
plate.) The light should be moved slightly to one side, 
so that it still falls on the shrimp, but not into the 
lens. A negative taken with the light in this position 
would give the result as shown in the second illustra- 
tion on the same plate. Next, without moving the 
light, a sheet of ground glass should be placed between 
the light and the animal. The crustacean is now illu- 
minated by a combined transmitted and reflected light, 
and the resulting photograph suggests transparency. 
As an illustration of how parts of this same crustacean 
can be photographed without its being moved, a higher 
power was now put on the camera, and a photograph 
taken of the part marked x, the result of which is 
shown in the top illustration on the next plate. The 
microscope can now be slipped into position and the 
part marked x x magnified up, as shown in the lower 
illustration on the same plate. 
I have mentioned various tanks and apparatus, 
but in addition to these, not infrequently I have 
built a special tank in order to obtain a single 
photograph. But if asked what apparatus I would 
recommend to anyone starting fish photography, I 
would say, construct a tank on the principles of the 
pond. 
On my next photographic holiday, I intend to take 
with me a wooden tank four feet square and two feet 
deep, with two opposite sides of plate glass. When it 
is desired to photograph a fish by a front light, I shall 
be able to use this box-like tank, as already described.
