HUNTING WITH A 
CAMERA 
(Continued from page 435) 
It also demands some skill in the use 
of the anaesthetic, as if the insect is 
not far enough “under” it will be, or 
will soon become, too active, while if 
too much ether is administered the in¬ 
sect will be killed and will be too limp. 
In photographing the posed insect, 
the camera of the “hand - and - stand 
type” is used at nearly full extension, a 
small stop is used to give depth of field, 
and a panchromatic plate with a filter 
is employed. The choice of a filter is a 
matter which demands considerable at¬ 
tention. In the majority of cases a 
filter giving full correction, such as the 
Ilford Gamma, or the Wratten K 3 , is 
the most desirable, but in some cases a 
little under correction, secured by the 
use of a lighter filter, or some special 
degree of contrast, which is secured by 
the use of the Wratten G or 23a filters, 
is preferable. If, for instance, a part 
of the pattern'or an insect consists of 
a certain shade of blue and a particular 
shade of red, full correction will render 
both colors as the same shade or gray 
and the pattern will be entirely lacking 
in the negative. In this case under cor¬ 
rection will render the blue lighter than 
the red, or the orange-red 23a filter will 
render the red lighter than the blue. 
It is only by a careful inspection of the 
insect through the different filters that 
the filter giving the most effective 
rendering can be selected. 
In insect photography, as in‘all other 
branches of nature photography, special 
attention should be given to showing in 
the picture as much of the habitat and 
the activities of the insect as possible. 
A series of photographs, showing the 
various stages in the life-history of a 
certain species—for instance the egg- 
cluster, the caterpillar in each instar 
(i. e. the stage between each moult), 
the spinning of the cocoon, the finished 
cocoon, the emergence of the adult, and 
the adults—male and female where the 
sexes differ in appearance—are particu¬ 
larly valuable. 
The methods of photographing spiders 
are similar to those for insects, but the 
photography of spider’s webs presents 
quite a different problem. The extreme 
delicacy of the silken strands of the 
webs renders it practically impossible 
to secure a good picture of the web in 
its natural environment and with its 
natural background. Something may 
be done by working very early in the 
morning after a foggy night, as the 
moisture on the strands renders them 
distinctly visible, but it .also makes 
them appear far thicker and heavier 
than they really are. Successful pic¬ 
tures may sometimes be made by hang¬ 
ing a piece of black velvet behind a web 
which is so placed that an effective 
lighting can be secured. It is, however, 
difficult to find an absolutely perfect 
web, as insects or wind make rents in a 
web very soon after its completion, and 
to obtain the best possible pictures of 
spider’s webs it is necessary to induce 
the spider to build one to order. To do 
this the branch with the web and its 
builder is cut off, transported to a 
greenhouse or a well-lighted room, and 
the cut end stuck in a flower-pot full of 
earth. The spider will usually repair 
the web, or spin a new one, within 
twenty-four hours, and the flower-pot 
may then be placed in the most favor¬ 
able position with regard to lighting, a 
piece of black velvet stretched behind 
the web, and a perfect picture secured. 
Aquatic invertebrates constitute a 
large assemblage of marine and fresh¬ 
water animals belonging to many dif¬ 
ferent groups—molluscs, (snails, clams, 
oysters, mussels, etc.), crustaceans 
(crabs, lobsters, shrimps, crayfish, bar¬ 
nacles, etc.), annelids (leeches, marine 
worms), echinoderms (starfish, sea- 
urchins, sea-cucumbers), coelenterates 
(jelly-fish, sea-anemones, hydroids), as 
well as aquatic insects. 
There are two methods of photograph¬ 
ing aquatic invertebrates—in their habi¬ 
tat, and in an aquarium. The former 
method is useful in that it shows the 
actual environment, but there are com¬ 
paratively few species which can be 
successfully photographed in this man¬ 
ner because the only point of view ob¬ 
tainable is from above and most ani¬ 
mals show to the best advantage when 
viewed laterally. 
In photographing aquatic animals in 
their habitat it is necessary to use an 
opaque screen to cut off the reflections 
from the surface of the water, as other¬ 
wise nothing but a while glare of sur¬ 
face reflection will show in the nega¬ 
tive, even though the images of the 
animals under the water may appear 
fairly distinct on the focussing-screen. 
Such a screen may be made of sheet 
zinc on a light wooden, or stiff wire, 
frame, or of thin wood weighted with 
lead at one edge, and should be at least 
three feet wide by four feet long. In 
use one end of the screen is placed on 
the bottom behind the objects to be 
photographed and the front edge of the 
screen supported by short poles at the 
corners, ' T so as* to bring the front edge 
of the screen just over the camera. In 
this work due allowance must be made 
in the exposure for the diminution in 
the light due to the screen, and it is 
necessary to see that there are no wind 
ripples on the water at the time of ex¬ 
posure and that there is no dirt floating 
on the surface of the water. 
The general directions given in the 
section on fish photography apply to 
the photographing of aquatic inverte¬ 
brates in an aquarium.
