First of all, PS is the processing of bitmap images, AI is processing vector graph graphics. Let's talk about the basic problem of the two, the difference between bitmap and vector diagram and its advantages and disadvantages.
In the field of computer graphics, digital graphics and images are divided into two types, "vector" and "bitmap", according to the different mapping principle and drawing method.
PS is the most excellent professional image editing software, make the diagram is a bitmap. Bitmaps are dots or pixels to record an image, so the image is made up of many small dots. The advantage is that the color display is natural, soft and lifelike. The disadvantage is that the image is distorted during zooming in or out, and the disk space that is occupied increases dramatically as the image accuracy increases or the size increases. The image becomes blurred when the bitmap is enlarged.
And like Ai, or CorelDRAW, freehand, etc. are used to draw vector graphics software, vector diagram, is a mathematical way to record graphics, made by the software. The advantage is that the amount of information stored is small, and the resolution is completely independent, the graphics in the size of the enlargement or reduction process of the quality of the graphics will not be affected in the slightest. The disadvantage is to use mathematical equations to describe the graph, the operation is more complex, and the system makes the graphic color is more monotonous, the figure looks more stiff, not soft and realistic.
In the case of little complexity of the graph, the vector graph has the advantages of short file and stepless scaling.
Next, compare the PS and AI two software, and look at their applications now.
Photoshop is a very good professional image processing software, has been occupying the image processing software leader position, is the graphic design, building decoration design, photography, three-dimensional animation production and web design, such as the necessary software. Its amazing features also arouse the keen interest of amateur image processing enthusiasts.
Illustrator is the world's most famous graphics software, with its powerful features and thoughtful interface has occupied a lot of convenient vector editing software in the majority of the share. Incomplete statistics, 67% of the world's designers use illustrator for artistic design. Illustrator can be used by both the designer and professional illustrator, the artist who produces the multimedia image, or the creator of the online content of the Internet page. But it is not limited to use it for advertising works, newspaper illustrations, poster posters and other emphasis on the performance of vector graphic effect. Its bitmap processing capability is still strong. Especially with Photoshop powerful combination, so that the user's creative environment has become particularly broad.
