As the price of memory fell it became feasible to apply the concept of layering to raster images.
LALF's terminology for layers is "cells", after the concept of drawing animation frames over-top of a stencil.
Layers were introduced in Western markets by Fauve Matisse (later Macromedia xRes),[2][better source needed] and then available in Adobe Photoshop 3.0, in 1994, which lead to wide-spread adoption.
In graphics software, layers are the different levels at which one can place an object or image file.
Each layer may bear individual settings, such as opacity, blending modes, dynamic filters, and potentially hundreds of other properties.
The top layer (the bird) is moved to the left.
The top layer is moved to the right.
The top layer (the bird) is partially transparent, so the background clearly can be seen through its wing.
In this picture the top layer has a
drop shadow
, a red color overlay of 40%, a
gradient
overlay from red to yellow of 20% opacity, and a slight bevel effect.
This picture consists of a blue background and on top of that a layer of conifers cut using a layer-mask in the shape of a seagull.
The blue sky used as background layer.
The greenery used as top layer.
The layer mask that was applied to the top layer. The white shape is a mask over the black.
A gradient is applied as an adjustment layer to the entire image except for the oval in the middle, which was cut out from the adjustment layer.
