How to make your own pictures

I work in this line, so I know everything you say, but typing such an article will kill people.

Say it briefly ~

Photoshop and CorelDRAW are both drawing software. One is bitmap making software, which is more conducive to design, and the other is vector drawing making software, which is more conducive to printing, splicing and word processing.

If you set up an image (or graphics) studio, you need a lot of software and instruments. First of all, you need to know whether you are doing a 3D graphic studio or a graphic studio. If you are taller, you may even use a non-linear knitting machine. First of all, a burner and more than three computers in a local area network are necessary, and the power box prevents power failure. If you just want to be an illustrator, you can have a laptop. Secondly, in addition to the software mentioned above, such as typesetting software, some software for making business cards, such as Montay and Illustrator, are also commonly used.

As for the layer, it should be related to space science. Metaphor exists between every object. Different colors will convey different emotions. Just like people, grades and block sizes are also the main ways to express emotions. In Photoshop, the layer is more like a special effect tool, which can achieve more dazzling effects. Layer is more like the role of a gardener. With the emergence of layers, the spiritual world can communicate.

As for the path in CorelDRAW, it should be easier to adjust. Compared with the rigid operation in Photoshop, it is a headache in PS. Many tedious operations are not as simple as those in CorelDRAW, and the paths between many softwares are interoperable. For example, PS has the function of importing paths in import. Now I use these path files directly on the Internet and seldom draw them myself.

Channel, this is a term that was born in printing. Some old typesetting softwares are still used in printing plants today, because they are born for channels and are also "people" who know channels best. Channel is the birthplace of color. Of course, we can also create more spot color channels. Ordinary printing CMYK should be the most popular channel mode. When we are making pictures, we can also use channels to make some monochrome adjustments. Or RGB, the channel of light and color principle, which is more suitable for the network. LAB is more suitable for things like scanners, because it won't fade. As for the spot color channel, it is generally used with high-grade printed matter and special ink, such as RMB printing that we have long seen.

Let's talk about color system first. Actually, it doesn't have to be so complicated. Simply put, it is the number of different colors in the same color system. The color systems used by monochromator are dark gray, light gray and black and white. In this way, complex picture effects can be displayed simply. For another example, the display uses RGB primary colors to reflect light with different intensities in a triangle on the screen to display the picture. We can also manually adjust the radiation intensity of a certain light to make the screen achieve a more ideal visual effect.

As for the resolution of an image, in terminology, it is a parameter used to measure the amount of data in a bitmap image. Usually expressed in ppi (pixels per inch). The more data it contains, the longer the graphic file and the richer the details. In daily life, the resolution on the network is generally 72 or 96 pixels, and it is generally 300 pixels when printing. As for how to measure him with various instruments, as I said above, it depends on what you want to do. Changing the resolution in PS is very simple. When creating a new file, there is a resolution setting, or there is an information bar showing the file name above the file box that has been opened, and then right-click to select the image size to adjust.

There are many formats for saving photos, but the most common ones are JPG, TIFF and BMP. As for the saved software, there are many kinds of software for looking at pictures, such as the simplest "drawing" or the ACDEE that comes with the system, or the complex PS can save pictures.

The most commonly used image format in the network is GIF or JPG. When saving, you can choose RGB colors and save them in these two formats.

As for channels, I have already said something above. In addition to adjusting the number of each color in PS, we can also use the channels in PS to do various effects, such as selecting a single color and making lettering through new channels. However, with the improvement of PS function, the channel has gradually withdrawn from our sight.

Graphic format, this time will naturally have their own experience.

I picked up such detailed information directly from the internet. Have a look.

File format is a format for saving files in different ways. Photoshop supports dozens of file formats, so it can well support various applications. In Photoshop, the common formats are PSD, BMP, PDF, JPEG, GIF, TGA, TIFF, etc.

1.PSD format

PSD format is the inherent format of Photoshop. PSD format can open and save images faster than other formats, and well save layers, channels, paths, masks and compression schemes without data loss. However, few applications support this format.

2.BMP format

BMP(Windows Bitmap) format is the inherent format of Microsoft Pain developed by Microsoft, which is supported by most software. BMP format adopts a lossless compression method called RLE, which will not have any impact on image quality.

3.PDF format

PDF (Portable Document Format) is a file format created by Adobe Systems, which allows electronic documents to be viewed on the screen. PDF files can also be embedded in HTML documents of websites.

4.JPEG format

JPEG (short for Joint Photographic Experts Group) is the most commonly used image format. It is the most effective and basic lossy compression format, which is supported by most graphics processing software. JPEG images are also widely used to make web pages. If the image quality is not high, but you need to store a lot of pictures, then using JPEG is undoubtedly a good way. However, it is best not to use JPEG format for image output printing, because it improves the compression quality by damaging the image quality.

5.GIF format

GIF format is the most commonly used format for outputting images to web pages. GIF adopts LZW compression, and the color is limited to 256 colors. GIF format is represented by 87a and 89a codes. GIF87a strictly supports opaque pixels. GIF89a can control the transparency of those areas, thus greatly reducing the size of GIF. If you want to use GIF format, you must switch to indexed color mode so that the number of colors is 256 or less.

6.TGA format

TGA(Targa) format is the most widely used image file format on computer, which supports 32 bits.

7.TIFF format

TIFF(Tag Image File Format) was developed by Aldus in the early days of Mac to standardize scanned images. It is the most widely used image printing format on Mac and PC platforms. TIFF uses LZW lossless compression, which greatly reduces the size of the image. In addition, the most exciting function of TIFF format is to save channels, which is very beneficial for you to process images.

Filter:

Filter is one of the most common and peculiar tools in PhotoShop. Filters change pixel data in different ways to achieve the special processing effect of abstract and artistic processing of images.

There are three kinds of Photoshop filters: internal filters, internal filters (self-contained filters) and external filters (third-party filters).

Our most commonly used external filters are KTP and rock sugar. KTP was first famous for its lightning and a series of realistic special effects, and rock sugar is also good at it, just like its name, water drops and glass.

As for the built-in, there are many, stylized, plaid, turtle-cracked, and many more. If you use them more, you will find many things that belong to you. As for from 7. Many new filters, liquefaction, etc. These are all introduced after 0, which can't be explained in the book, and it takes a long time to understand.

The latter two parts are a little missing, and many terms are picked from the internet. I'm too tired to write any more. I hope it will help you on the road of design.
