A photograph is created when light is allowed to fall on a light-sensitive medium.
The pattern of light creates an image that is recorded by the photographic device.
How light or dark a photograph is depends on how much light was allowed to fall on the light-sensitive medium
a light-tight box that contains a light-sensitive material or device and a way of letting in a desired amount of light at particular times to create an image on the light-sensitive material
A traditional still-film camera has three different components: the mechanical element, the camera body, and the parts associated with it. The chemical element is the film.
The optical element, the _____, is a curved piece of glass through which light rays are refracted to either converge or diverge, forming an image.
The glass of the lens slows the light down from its speed in air. Since the light waves enter the glass at different times, the lens will bend the light in one direction.
will bend the light toward the center of the lens because one or both sides of the glass curve out. It also takes the various rays of light and bends them toward the same point to form an image
converging or convex lens
The magnification of a lens, or ____ _____, is the distance between the lens and the subject.
_______ lenses are those that magnify an image or make an object seem closer than it really is. In contrast, a wide-angle lens shrinks the object in front of it with a shorter focal length.
A camera uses either a light-sensitive device (film) or a digital sensor to capture an image.
Color film normally has three light-sensitive layers that react to the colors blue, green, and red.
A _____ opens and closes between the film and the lens, giving the photographer control of letting light in. The eye lid is similar to the shutter, it opens and closes to let it in or shut out light.
The _____ _____ is the length of time that light is let into the camera in order to expose the film.
_______ is the lens opening that allows us to control the amount of light that reaches the film or digital sensor.
Aperture is controlled by the _____ _______ a set of overlapping metal plates that expand out to allow more light or fold in on each other to reduce the amount of light.
he size of the grain is indicated by the film's _______.
Digital cameras have _______ settings, the equivalent of film speed.
When you point the camera at your subject, light bounces off the subject and enters the camera. The light passes through the lens and onto a mirror, located between the lens and the shutter.
This mirror reflects the light upward to a _______, which is a five-sided mirror.
One of the earliest cameras made was a _____ _____.
Pinhole cameras are light-tight boxes that have a small hole. Light passes through this hole and creates an inverted image on the opposite side of the box. Pinhole cameras do not use a lens and have a very small aperture.
_____ ____ ____ cameras are those that use an optical viewfinder instead of a semiautomatic mirror
Point and shoot
An ___, or _____ ____ ____, camera has a semiautomatic movement of the mirror, which produces an exact image in the viewfinder.
SLR, or single lens reflex, camera
SLR cameras exist in both digital and traditional film forms. Since the 1970s, most professionals use SLR cameras. A dSLR is a digital version of the traditional SLR camera.
______ cameras use an electronic image sensor to digitally record an image.
A _____ is the smallest unit of the picture that can be controlled.

The Tagged Image File Format
_____ zoom works like a telephoto lens
_______ zoom crops the image and enlarges the cropped image to fill the frame of the camera which can result in a loss of quality.
The ______ ______ is an adjustment that can be made to the color so that whites will appear white in the photograph instead of yellow or blue.
