THE BIRD PHOTOGRAPHER'S OUTFIT 13 
These enlargements may be made with an en- 
larging camera or with the aid of a Nehring enlarg- 
ing lens, which is placed between the front and back 
lenses of the view lens, when, with the ordinary 
long-focus camera, a magnification of about four 
diameters may be obtained, the image being thrown 
on to a piece of bromide paper in the plate holder. 
Through enlargement many apparently worth- 
less negatives become of value, and in some in- 
stances pictures can be made from different parts of 
the same negative. From the sportsman-photog- 
rapher’s standpoint there is, however, one objection 
to the use of a magnifying lens. It gives deceptive 
results, and those who are not familiar with its 
powers are apt to accord the photographer undue 
praise for his apparent skill in successfully ap- 
proaching some bird or beast which may have been 
far out of range. A not wholly unrelated kind of 
enlargement is sometimes applied to the contents of 
creels and game bags! 
But the animal photographer is so heavily handi- 
capped that in this case the end assuredly justifies 
the means. As a matter of information, however, it 
seems eminently desirable to accompany all enlarged 
pictures by a statement of the extent of their mag- 
nification, and throughout this book this plan is fol- 
lowed. Consequently, when there is no mention of 
enlargement, it may be accepted as a fact that the 
print from which the reproduction was made was 
obtained from the negative by contact. 
In illustration of these suggestions in regard to 
the proper lenses for bird photography, a series of 
pictures is presented which shows the results to be
