In time exposure photography, an object that is only partially recorded on the film and therefore has a translucent, ghost-like appearance. Ghosting also occurs when using electronic flash at a slow shutter speed, and a second image is captured on the film by ambient light. Some people also refer to "flare" as a ghost image.
A type of flare occurring when the sun or other strong light source is included in the scene and a complex series of reflections among the lens surfaces causes a clearly defined reflection to appear in the image in a position symmetrically opposite the light source. This phenomenon is differentiated from flare by the term "ghosting" due to its ghost-like appearance. Ghost images caused by surface reflections in front of the aperture have the same shape as the aperture a ghost image caused by reflections behind the aperture appears as an out-of-focus area of light fogging. Since ghost images can also be caused by strong light sources outside the picture area, use of a hood or other shading device is recommended for blocking undesired light. Whether or not ghosting will actually occur when the picture is taken can be verified beforehand by looking through the viewfinder and using the camera's depth-of-field check function to close down the lens to the actual aperture to be used during exposure.
a faint, smaller sized version of the applicant's digital photo image
(a.k.a. marquee) an image that appears on the screen when you drag an object from one location to another. The ghost image is usually the same shape and color as the object, but contains no associated text.
A vague image project off one, this condition is not normal and may require some correction.
is a fainter second image of the object you are viewing.
Internal reflections from the lens surfaces often referred to when describing the benefits of an anti-reflective coating. Ghost images are mostly experienced at night, but may also be seen under fluorescent lights and when viewing computer screens. Go to Top
the grayed-out shell of a diskette icon or menu option that is either not available (as for example the "paste" option when no chunk of text has been specified, or of a diskette that has been ejected with the Eject option instead of dragging to trash). Ghost images can be a problem when the MacOS is waiting for a previously ejected diskette, and a student in your class is prompted to insert a diskette from a previous class. To interrupt the cycle, press -. (command-period) and hit OK, and the ghost will be exorcised.

In time exposure photography, an object that is only partially recorded on the film and therefore has a translucent, ghost-like appearance. Some people also refer to " flare " as a ghost image. Bright spots of light, often taking the shape of the aperture, which appear in the camera viewfinder or in the final photograph when a lens is pointed at a bright light like the sun; controllable through the use of multilayer coating of the lens elements.
