An opaque image used to block the view in one area, but with holes allowing the image to be viewed in other areas. An object is masked when part of the object is hidden because it is pasted inside a path that is smaller than the object.
in computer graphics, an image with only two values (black and white) used in conjunction with another more detailed image to mask out, or clip, parts of the image, so as to indicate areas of transparency, or edges of the image, etc.
A term that denotes an intermediate photographic negative or positive used in color correction. Masking prevents light from reaching certain areas during exposure of an image on printing plates. It enables one to apply an effect to one part of an image and not to the other, or to vary the strength of an effect on an image. It is sometimes termed a knock out. Mask similarly means to block out certain parts of a negative (or any image) with paper, tape, paint, or another material, to cause that area to print white. Masking can also be performed digitally with the use of image editing programs. See also GOLDENROD PAPER IMAGE EDITING MASKING MATERIAL NEGATIVE OPAQUE POSITIVE
A function within image editing software that allows the user to restrict their image edits to only a part of the image. A mask can have a hard or soft edge allowing the user to achieve a variety of obvious or subtle effects.
Using an opaque material to block parts of an image from light exposure, also called knockout
Tracing an object, or portion of a photograph, with an image manipulation program prior to applying a different creative effect to it, like a blur, different coloured ink, or texture. Material used to shield artwork or film from additional retouching or exposure to light.
This tool is used to select a portion of an image. This selection can be altered without affecting the other parts of the image.
(sc) a glass plate covered with an array of patterns used in the photomasking process. Mask patterns may be formed in emulsion, chrome, iron oxide, silicon or a number of other opaque materials.
A selection, object, or ALPHA CHANNEL used to block out part of an image. A mask can be used to crop an image to a certain size or shape, or to protect part of an image while the image is being modified.
Mask is any material used by printers to block out areas on the negative or printing plate that should not print. Alternatively, the process of blockig out such areas.
Consists of selecting an area in an image so that the area alone can be altered by an effect. Conversely, an inverse mask will allow the area outside of the mask to be modified by the application of an effect.
a binary image that defines objects in the scene, the motion of which is to be tracked. The frame which the mask is associated with is called the key frame.
An opaque overlay placed over any part of a photo or separation negative that should not be exposed to light.
An image or clip used to define areas of transparency in another clip. Similar to an alpha channel.
An image whose values indicate particular properties of another image or matching size. A mask might specify bad detector element or relative errors of pixels.
A glass plate that is selectively patterned with chrome or another opaque material. The mask is used to transfer a master image to a silicon wafer or other substrate.
An opaque screen placed in the camera or printer that blocks part of the frame off and changes the shape of the photo-graphed image, leaving part of the frame a solid color. As seen on the screen, most masks are black, although they can be white or colored.
a bitmap used for drawing bitmaps -// it can be a monochrome bitmap or a multi-bit bitmap which transfers to alpha channels -// transparently
a flat, transparent quartz plate containing microscopic photographic images of electronic circuits
a graphical object that is placed on top of another image and given instructions on how it should interact with its partner

a media file with an alpha (transparency) channel, which is used to make areas in another image transparent
a monochrome copy of your bitmap where everything in the picture is black and everything that should be transparent is white
an area of a layer which can be made completely or partly transparent
an area of opaque material on a clear overlay which prevents light from striking and therefore exposing an area on a negative or positive during the photomechanical process
an edit able image that controls the transparency of the layer it's associated with
a separate object that you can apply to a layer to make parts of your image on the layer transparent
a "shadow" image of your scene
a shape that obscures part of an image
a special bitmap consisting of only two colors, black and white
a transparent optic that has part of its aperture blocked with a pattern of opaque material
a vector path which allows part of an object to show while blocking out the rest effectively making part of it transparent
A bitmap pattern in BMP format applied to a texture, having shades of darkness to determine which parts of the actual texture appear transparent in AW and which opaque
A 256 color grey scale bitmap similar to a stencil. It has "open" areas that allow changes to the image and "closed" areas, that do not. white is a completely "open" area, black is completely "closed" and shades of grey allow varying degrees of changes to be made to the image. Mask Tutorials
A photographic film placed over an image in order to modify the light that will pass through the image, thereby changing a characteristic of the reproduction. This task can also be handled electronically on digital prepress systems. There are a variety of masks, including area masks, outline masks and unsharp masks.
A selective barrier to the passage of radiation. Masks, metal on glass: An optical mask comprising a glass substrate selectively covered by thin, opaque metal layers, a photomask type.
A blank graphic that covers a portion of the screen to allow another image to show through.
A mask divides an image into two regions: A region where the image is colored by the coloring formula and a region which is colored with a solid color. The solid color can be transparent or partially transparent (use of the alpha channel) to allow layers underneath to show through.
Photographically isolating one part of an image for color correction, contrast reduction, tonal adjustment, or detail enhancement.
A material applied to enable selective etching, plating, or the application of solder to a printed circuit board.
Many image-enhancement programs have the ability to create masks--or stencils--that are placed over the original image to protect parts of it and allow other sections to be edited or enhanced. Cutouts or openings in the mask make the unmasked portions of the image accessible for manipulation while the mask protects the rest.
One of the Four Faculties, the image of what we desire, wish to become, revere, or regard as good.
The inactive area of a bitmapped image that will not respond to changes.
(1) A sheet of thin black paper, metal, or celluloid normally used to obtain white margins on a photograph. (2) Any material used over a print or negative to obscure a part of the image. (3) A raster representation of a region.
A tool that protects areas of an image. Masking permits you to apply an effect to one specific part of an image or to vary the strength of an effect within an image.
To block off a background or other area, so that the unmasked area can be printed. Also, to enclose a portion of an image so that it can be manipulated without affecting the unmasked area.
Blocking light from reaching parts of a printing plate.
The blocking out of a portion of the printing plate during the exposure process.
A monochrome graphical image.
Made up of bitmap image data, a mask is used to define a selection of applications, such as layers or channels. "Pre-masked" images (such as Photo-Objects images) have already gone through this process and possess a transparency. Read about using images with masks on our Help page.
Whether covering only the head or the whole body, whether a naturalistic image or a strongly stylized form, masks are originally and universally regarded as representations of the greater powers.
This is a process used to delete unwanted areas of an image while maintaining its shape.
Opaque material or masking tape used to block-off an area of the artwork.
A flat, transparent plate that contains the photographic image of wafer patterns to define one process layer.
(1) Opaque material (usually thin plastic) placed in front of the lens like a filter to block some of the light entering a lens. The mask may have a cut-out shape (a keyhole or heart-shape, for example) or may block half of the image frame to facilitate a double-exposure. (2) Opaque frame used to hold down the edges of photographic paper when making a print. Since the margin area beneath the mask is not printed, the print will have a white border.
A special effect you paste images through so that you can only see part of the images, or so that they blend into the background.
a glass plate with a pattern of transparent and opaque areas used to photolithographically create patterns on wafers. A mask is commonly used to refer to a plate that has a pattern large enough to pattern a whole wafer at one time. See also, reticle.
A defined area used to limit the effect of the image-editing operations to certain regions of an image; masks can be drawn manually with a stylus or a mouse, or they can be created automatically.
To prevent light from reaching part of an image, therefore isolating the remaining part. Also referred to as knock out.
Opaque overlay which masks out the unwanted portion of a photograph.
In offset lithography, an opaque material used to protect selected areas of a printing plate during exposure. "Masking" can also be performed digitally with sophisticated image editing programs.
To cover part of an image so it will not be affected by other operations.
In electronic imaging this refers to the lithography process used to produce an imaging sensor. To make an imaging sensor requires many masks that represent each layer of the architecture.
An opaque material used to protect open or selected areas of a printing plate during exposure.
If you want two images to overlap, one of those two images must be partially stamped. To do this, you use a mask. A mask is a piece of paper. For more info, see "Techniques-Masking"
An opaque material used to cover the edges of the printing paper, and thus produce borders when the paper is exposed to light.
output: The act of covering up a portion of an image either to avoid seeing it or to protect it from some process you intend to perform on the unmasked portion. This term is also used as a noun for the thing itself.
A defined area used to limit the effect of image-editing operations to certain regions of the image. In an electronic imaging system, masks are drawn manually (with a stylus or mouse) or created automatically--keyed to specific density levels or hue, saturation and luminance values in the image. It is similar to photographic lith masking in an enlarger.
