Dear you, this is LearningYard Academy.

What Xiaobian brings to you today is<talking about PS series (17)|Explanation of layers in ps.

PART.1.

1、图层

通俗来说,图层就像是含有文字或图形等元素的胶片,一张张按顺序叠放在一起,组合起来形成页面的最终效果。图层可以将页面上的元素精确定位。图层中可以加入文本、图片、表格、插件,也可以在里面再嵌套图层。

ps图层的概念(lt谈ps系列17)(2)

Generally speaking, a layer is like a film containing elements such as text or graphics, which are stacked one by one in order to form the final effect of the page. Layers can precisely position elements on the page. You can add text, pictures, tables and plug-ins to the layer, or you can nest layers inside.

图层是存在层级关系的,层次最直接体现的效果就是遮挡,位于图层最下方的图层为背景,一般是背景白板。位于图层调板下方的图层层次是较低的,越往上层次越高,就好像从桌子上渐渐往上堆叠起来的一样,位于较高层次的图像内容会遮挡较低层次的图像内容。合理利用好层级关系,就可以达到某些图片在上方,某些图形在下方的效果。

Layers have a hierarchical relationship. The most direct effect of layers is occlusion. The layer at the bottom of the layer is the background, usually the background whiteboard. The layer level below the layer palette is low. The higher the layer level is, the higher the layer level is, as if it is stacked from the table. The image content at a higher level will obscure the image content at a lower level.Make good use of the hierarchical relationship to achieve the effect that some pictures are at the top and some graphics are at the bottom.

二、图层种类

ps中图层分为四种:位图,智能对象图层,矢量图层,调整图层。

位图就是我们平时显示的最基础的图片。

智能对象图层:智能对象是包含栅格或矢量图像中的图像数据的图层。是对其放大缩小之后,该图层的分辨率也不会发生变化。

矢量图层:矢量图使用直线和曲线来描述图形,这些图形的元素是一些点、线、矩形、多边形、圆和弧线等等,像我们上节课提到的创建矩形随之创建的矩形图层就是典型的矢量图层。

而调整图层可将颜色和色调调整应用于图像,而不会永久更改像素值。

2、 Layer Type

There are four layers in ps: bitmap, intelligent object layer, vector layer and adjustment layer.

Bitmaps are the most basic images we usually display.

Smart Object Layer: A smart object is a layer that contains image data in a grid or vector image. After zooming in and out, the resolution of the layer will not change.

Vector layer: The vector map uses lines and curves to describe the graphics. The elements of these graphics are some points, lines, rectangles, polygons, circles and arcs. For example, the rectangle layer created after creating a rectangle mentioned in the last lesson is a typical vector layer.

Adjusting the layer applies color and tone adjustments to the image without permanently changing pixel values.

这里调整图层最为特殊,调整图层所在的位置在图层栏下方的圆形位置,在这里可以选择需要我们调整的元素,创建图层后就可以对所有图层进行调整。例如如下图所示,创建了亮度/对比度的图层,就可以对所有下层的图层进行亮度和对比度的调整。

Here, the adjustment of the layer is the most special. The position of the adjustment layer is in the circular position below the layer bar. Here, you can select the elements that need to be adjusted. After creating the layer, you can adjust all layers. For example, as shown in the following figure, if you create a brightness/contrast layer, you can adjust the brightness and contrast of all lower layers.
