Adobe Photoshop generates a pseudo-random noise dither pattern on startup, with each pixel location in a 2D raster array assigned a gray value (R=G=B) and an alpha value of 1 ("on"). As the opacity of the top layer is reduced, the alpha value of some of the gray pixels is switched from 1 to 0 ("off"), with the result that image pixels ...

For painting with the dry brush a small amount of oil is used. The color is diluted with a few drops of linseed oil or solvents. From this mixture very little color is added to the brush. In the next step the brush with the color on it is spread out very well on a color palette and the oil is secreted. The brush must be dry at the end of this step.
