How to Know Your Camera
The camera once bought and in your hands, the next thing to do is to become thoroughly acquainted with it. With your camera you are entitled to a little book of instructions. Take your camera and the book, sit down alone, and give them your entire attention. Read the book carefully and, at the same time, carry out the instructions while the camera is unloaded, that is, without the film. If the size of the diaphragm can be changed, change it and look into the lens to see the effect; also try adjusting the shutter and watch the lens for the effect of instantaneous and time exposures. Try the focussing scale, locate some image in the finder, and practise holding the camera pressed closely against your body, pointing neither up nor down, tipping neither to one side nor the other, but aimed directly at the object you are supposed to be photographing. Then try turning the key which brings the film exposures into position.
