rangefinder cameras
Rangefinder cameras like most 35mmcompacts and APS models don't allow you to look directly through the camera lens to compose your picture. Instead a rangefinder window through the camera body helps you do the job. Better cameras have coupled rangefinders that adjust when you zoom in and out of a scene to avoid parallax error.
Rasterize
To convert vector graphic artwork into bit mapped artwork
red eye
In dim light the pupil in your eye opens wider in order to let you see clearly like a wide aperture in a camera lens. Red eye; when the people in your pictures seem to have glowing red eyes; is the result of your flash bouncing back off the eye's red retina. You can solve this by using a red eye reduction setting which fires a tiny pre-flash to decrease the size of your subject's pupil before it takes the picture.
resolution
In digital imaging the term resolution is used to describe several overlapping things. In general high-resolution images are made from millions of pixels and produce good prints. Low-resolution images on the other hand have fewer pixels and are only useful for computer monitor displays.
RIP
Raster Image Processing: to rasterize a file for output. When a page layout document such as a Quark file is RIP'ed all of the page elements (typography photography Illustrations and Graphics) are assembled and rasterized into a Bit Mapped image to be output. It is in the RIP that the halftone screens are applied to the artwork.
