Everything on Taking Photos

Taking photo with an analog camera requires certain settings. Before photographing one needs to adjust shutter speed, the diaphragm and the ISO. The shutter speed is the interval at which the shutter opens to allow a specific amount of light to pass through and expose the film inside. The aperture diaphragm determines how far a lens is opened, which also regulates amount of light entering the camera and onto the film. The ISO is traditionally used to "tell the camera" the film speed of the selected film. The ISO is determined by the type of film one is using, therefore its set prior to taking photos and cannot be changed throughout the roll.

Other than settings, a photographer must also ensure he’s using the correct equipment. One significant tool is the lens. Camera lenses are made in a wide range of focal lengths. They range from wide angle, standard, and telephoto. Each lens is best suited for certain types of photography. For instance the wide angle may be preferred for architecture because it has the capacity to capture a wide view of a building. The normal lens, because it often has a wide aperture, is often used for street photography and the telephoto lens is useful for sports, and wildlife since it can capture things in motion, though it is also more susceptible to shakes.

When photographing, one adjusts the sharpness of an image by turning the focus ring. One should never attempt to force the focus ring when the camera is set in auto focusing mode. This may damage the camera. The depth of field should also be considered. This is the distance between the nearest and furthest objects in a scene that appear acceptably sharp in an image. A lens can precisely focus at only one distance at a time, and decrease in sharpness other parts of the image. In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. When one presses the button on an SLR camera, the mirror flips up exposing the film to the light coming through the lens.

Later through the use of chemicals – water, fixer and developer – the film can be developed and later the photos can be printed on paper either by scanning them into a computer or through traditionally using an enlarger.
