- 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.
