What is painted black on the layer mask will not be visible in the final picture. What is grey will be more or less transparent depending on the shade of grey. As the layer mask can be both edited and moved around independently of both the background layer and the layer it applies to, it gives the user the ability to test a lot of different ...
Color positive picture (A) and negative (B), monochrome positive picture (C) and negative (D) In photography, a negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest.

The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene.
Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background painting. In film and stage, mattes can be physically huge sections of painted canvas, portraying large scenic expanses of landscapes.
The anti-halation layer is rendered transparent or washed out during processing of the film, for example, the K-14 process for Kodachrome still film and the Eastman Color Negative (ECN2) process for color motion picture film both have steps which remove this layer.
A dark frame, or an average of several dark frames, can then be subtracted from subsequent images to correct for fixed-pattern noise. [1] It is important that dark frames are taken at the same ISO sensitivity and exposure time as the original photo, because the brightness of fixed pixel noise is dependent on both. [1]
Eyeglass frames are commonly made with cellulose acetate. Industrial uses: cigarette filters and other filters, ink reservoirs for fiber tip pens. High absorbency products: diapers and medical aid products. The original Lego bricks were manufactured from cellulose acetate from 1949 to 1963.
A TIFF file also can include a vector-based clipping path (outlines, croppings, image frames). The ability to store image data in a lossless format makes a TIFF file a useful image archive, because, unlike standard JPEG files, a TIFF file using lossless compression (or none) may be edited and re-saved without losing image quality.
