10. — Blurred portraits, similar to the example shown, are very common among users of " fixed focus ” box cameras. In such cameras the lens is so placed that objects about 25 feet away appear sharpest in the picture. Twelve feet is about the nearest limit for clear results. Within this distance, the nearer the object is to the camera, the more blurred it becomes. Hence the fuzzy faces.
Prevention. — Buy and use a portrait attachment (or a focussing camera). This attachment is an extra lens, made to fit on the front of the existing lens, and which causes a sharp pic¬ ture to be produced if the object is at a certain stated distance — and at that dis¬ tance only.
1 1 . — Here is another kind of “ fuzzigraph.” In this example, the lens of a folding camera was not drawn out far enough, and the blurred image it passed did not reach to the ends of the film. This fault is most likely to occur with small cameras of the “ draw-out ” type, where the front is grasped and pulled forward, tbe sides being sup¬ ported by metal “ lazy-tongs.”
In some models the front seems to stick before it is fully extended, and an extra
pull is necessary to action of opening.
Prevention. — Always make sure that the front is extended to its full limit before taking photographs.
12. — Those who have developed roll films by see-sawing them through a dish of liquid know how perverse a thing a strip of dry film is. It twists and ties itself into knots with exasper¬ ating stupidity before it can be persuaded to enter its bath. Parts of it get wetted and are developing while other areas are still dry. If you develop in total darkness the fun and your result
