The skunk.
Don't get too near when you try to photograph him.
Shutter Speed
To photograph objects in rapid motion such as flying birds, the speed of your shutter must be at least one three-hundredths of a second and you must have a fast lens; but with a shutter speed of one one-hundredth I have taken very good pictures of things moving at a moderate rate. A walking or slowly running animal, for instance, can be taken with a shutter speed of one one-hundredth. You should find out the speed of the shutter when you buy your camera, then you will not throw away films on things beyond its possibilities. "You press the button and we'll do the rest" doesn't work where moving objects are concerned.
Those who go a-gunning with the camera, stalk their game as carefully as any hunter with a gun, and for really good results the following method is the safest to adopt. Time and patience are required, but one does not mind giving these, the interest is so absorbing and the successful picture so well worth while.
Set Your Camera Like a Trap
The porcupine stood in the shade but the background was light.
Find the spot frequented by the animal or bird you are after, wait for it to go away of its own accord while confident and unfrightened, then set up your camera like a trap where the lens will point to the place the bird or animal will probably occupy upon its return.
