What opens between the lens and the film in order to create the photograph?

Digital cameras in use today create pictures made up of millions of pixels.

Rather than having a mirror within the camera that reflects the image, point and shoot cameras have viewfinder that goes directly through the camera, giving the photographer a slightly different angle on the scene that what the shutter will open to capture.

What type of zoom crops the image and enlarges this cropped image to fill the frame of the camera?

Which popular file format loses some of the information from the image?

Which type of lenses shrinks the image in front of it rather than magnifying it?

Aperture is the length of time that light is let into the camera in order to expose the film.

Pinhole cameras use a conflex lens.

An iris diaphragm is a set of overlapping metal plates that can expand out to allow more light or fold in on each other to reduce the amount of light.

Generally, each pixel in an image creates 25 bytes of data.

Aperture is controlled by what in the camera?

The magnification of a lens is also known as which of the following?

Digital cameras use an electronic image sensor to digitally record an image.
