Layers (digital image editing)

src: i.ytimg.com

Layers are used in digital image editing to separate image elements. Layers can be compared to transparencies where the image or image effect is applied and placed above or below the image. Today they are an integral feature of the image editor.

The first layer was commercially available on Fauve Matisse (later Macromedia xRes), and then available in Adobe Photoshop 3.0, in 1994, but today various other programs, such as Photo-Paint, Paint Shop Pro, GIMP, Paint.NET, StylePix , and even batch processing tools also include this feature. In a vector image editor that supports animation, layers are used to allow for further manipulation along the general timeline for animation; in the SVG image, the equivalent of the layer is "group".

Layer type

There are different types of layers, and not all are in all programs. They represent parts of the image, either as pixels or as modified instructions. They are stacked on top of each other, and depending on the order, determine the appearance of the final image.

In graphics software, layers are terms used to describe different levels where you can place objects or image files. In this program, you can accumulate, merge, or define layers when creating digital images. Layers can be partially blurred to allow the image portion in the layer to be hidden or displayed in a clear way in other images, or you can use layers to merge two or more images into one digital image. For editing purposes, working with layers allows you to go back and make changes within layers as you work.

Layer (base)

The default layer type is called "Layers" in most programs. It only contains images that can be superimposed on other images. Images can cover the same area as the resulting image, only a part of it, or, in some cases, a larger section of the final image.

Layer A can have certain transparency/opacity and a number of other properties. In high end programs like Adobe Photoshop, the base layer may have more than a hundred different possible settings. Although some of them overlap and deliver similar results, they give skilled users a lot of flexibility. Free programs like GIMP may not have many settings but well used they can often provide satisfactory results.

Two Layers can blend using one of several modes that produce different combinations of light and color.

Layer mask

The mask layer is connected to the layer and hides part of the layer from the image. What is painted black on the layer mask will not be visible in the final image. What the gray will be more or less transparent depends on the gray shadow. Because the layer mask can be edited and moved separately from the applicable background and layer layers, it gives the user the ability to test many different overlay combinations.

Adjustment layer

Adjustment layers usually apply common effects such as brightness or saturation to other layers. However, since the effect is stored in a separate layer, it is easy to try and switch between alternatives, without changing the original layer. In addition, adjustment layers can be easily edited, such as layer mask, so the effect can be applied only to the part of the image.
