The blacked-out areas to the sides of a front-projection screen.
a technique by which a portion of the movie's image on the screen is blocked out, thereby temporarily altering the dimensions of the screen's aspect ratio. For example, the movie scenes in Boogie Nights. See also iris shot.
An act of using a mask in an image editing program. See Mask
A technique for controlling contrast in the printed image. A detailed explanation of contrast masking is available on its own Web page.
a technique used to get the effect of stamped images behind each other, in front of another
Masking is the way in which stamped images are combined to make it appear that some images are in the foreground, while others are in the background. The first step in masking is to decide which image(s) will be in the foreground. Stamp each foreground image on a thin piece of paper (Post-It Notes work well). Cut out the image, cutting just inside the borders. This cut out image will become your mask. Next stamp your foreground image(s) onto your cardstock. Place the mask over the foreground image and stamp your background image(s). Any overlap between the two stamps will appear on your mask, rather than on the actual card. Note: If your mask paper is too thick, or not cut just inside the border of the image, you will have a slight gap where the foreground and background images meet.
Differential exposure of the plate image to balance fine copy with critical reverses or process colour imaging; need for masking is determined by plate exposure latitude.
A technique used to bring three dimensional effects to your artwork. An example would be stamping a bed of flowers then stamping a second image of the flowers onto a spare piece of paper. This paper is then cut out very closely to the outside lines of the image. It is often very helpful to use a post it note for the second image ensuring that a portion of the image is stamped over the sticky part of the paper. This then prevents possible errors if your mask moves as you complete your artwork, this can be very helpful if there is more than one mask used at a time. The mask of the flowers is then placed over the existing bed of flowers on your artwork and another stamp such as a tree is stamped into position straight over the cut out/masked flower bed. Once this masked flower bed is removed it brings to life the total image of the tree growing up behind the flower bed.
A technique of covering a stamped image to protect it from subsequent applications of color. A method used to create foregrounds and backgrounds. How to instructions: Stamp foreground image onto surface first. Restamp image on Post It Note(tm) Cut image out Align cut out image (mask) over foreground image. Stamp second image overlapping mask. Remove mask. Second image "appears" to be in background.
The application of material which limits the area of irradiation of an object to the region undergoing radiographic examination to minimse image deterioration due to scatter radiation.
Process of removing part of an image using a region mask.
Restricting the size of a projected image on a screen by the use of black borders around the screen. Also the restriction in size of any projected image or photographic print by the use of undercut aperture plates or masks and borders.
Consists of drawing a path around an area of an image so that that 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.
Masking lets you isolate the foremost part of your video so you can insert an image, movie or other video sequences as the background. This feature works similar to chroma-key.
Draping around a screen to create a specific projected image
Technique that allows manipulation of one area of an image while other areas remain unaffected.
