506. Naval Displays

Naval Displays. Photographing naval displays at night is almost impossible if there is any considerable amount of movement. Heavy seas, rapidly moving craft or high winds completely prevent any chance of making an exposure. For this class of work what is required is that the vessels be anchored and fully illuminated during the exposure. Using a stop F. 11 and a very fast plate, an exposure of at least 10 minutes should be given.

507. Street Photography

Street Photography. This is perhaps the most fascinating form of night photography; a street corner with a little church steeple, or, perhaps, a statue sharply silhouetted against the sky, are good subjects. The exposure will vary from half an hour for a close view with few lights to 15 minutes for an open view, such as a large square, using stop F. 11 and employing a rapid plate.

508. In wet weather the streets and other outdoor places look their best. Lights, exceptionally clear and bright, stand out of the darkness and cast reflections over the pavements (See Illustration 46, "The Plaza"). Under such conditions the exposure may be reduced to 1 minute,- less than would otherwise be given if the streets were dry. Some churches, when well lighted at night, present very pretty pictures, especially if the stained glass windows are well illuminated. This class of night subject is the only one for which the use of rapid orthochromatic plates is recommended. With a stop of F. 11, an exposure of 30 to 40 minutes should be given. In all other classes of night photography the ordinary rapid plate will suffice, as it will be found that instead of orthochromatic plates being quicker at night they are, if anything, slower. Then, again, they have to undergo such prolonged development that there is every risk of either chemical fog or light fog taking place.

509. Railway Stations At Night

Railway Stations At Night. A large railway terminus offers ample scope for photographic work, but great care has to be taken to avoid moving lights. Owing to the close proximity of arc lamps, double-coated plates, or backed plates, are an advantage. Exposures may be very quick. With a rapid plate and an aperture of F. 8, a fully exposed negative should be obtained in 2 minutes.

510. Ship And Harbor Scenes

Ship And Harbor Scenes. Shipping always lends itself to pictorial treatment, and on a fine clear night very good pictures may be obtained. Exposures are approximately the same as for street work, i. e., with a rapid plate well backed, a lens stopped to F. 11, 5 to 10 minutes' exposure will be required.
