　　Medium and small eye shadow brushes are used to superimpose other dark colors on the background color. The skill of using them is to bring colors from bottom to top. It is recommended to prepare two medium eye shadow brushes, one with light color and the other with dark color.

　　Detail smudge brush

　　This eye shadow brush looks the same as the base brush, but it is actually the smallest size. The bristles may be only about 3mm, which is used to superimpose the heavy colors at the end of the eyes, or to draw some dark colors into eyeliner.

　　Contour brush

　　This brush is bigger than the base brush. It can be used after painting the whole eye shadow, without any powder. It just sweeps the edge of eye makeup to make the color more natural without obvious edge feeling, and it can also be used to sweep the nose shadow.

　　Eye shadow color

　　If it is not necessary for special occasions, it is best not to use too many colors in an eye makeup.

　　The background color means that the color of a large area of eye socket must be matte, not necessarily light, but it is best to be matte without flashing, which will make the whole eye feel less swollen.

　　The color superimposed on the background color is called the theme color. You can choose a brighter color, and the smudge range is less than the background color. How to say this range? You need to practice more. If you are a girl with double eyelids, you should control it around two or three millimeters. The color that is aggravated in the triangle area at the end of the eye is called the finishing touch color ~ when sweeping the end of the eye, bring a little to the lower eyelid part of the end of the eye to make the eyes deeper.

　　Finally, brighten the color, with sequins or flashing colors, embellish the eyes, eyes and lower eyelids, which can make the eyes more stereoscopic and deep ~

The tablet PC market has formed a three-legged situation: IOS system, Android system, and Windows system. There are also tablet on the market equipped with Google’s latest Chrome OS, but because there are fewer products, they are not included in the comparison for the time being. A detailed evaluation will be made after the Chrome OS product lineup is formed in the later stage. However, the systems are different. They are all tablet, but there are great differences. Next, I will share with you the differences in software and hardware between the tablet computers of these three systems.pass custom android tablet It can be seen from the present situation that the market prospect is relatively broad, which is conducive to our reference and investment. https://txsongseng.com

　　The motherboard structure of Android and IOS tablet PC is similar to that of mobile phones. Some tablet modelswill integrate baseband modules on the motherboard to enable the tablet computer to support mobile communication services (cellular networks), such as 3G and 4G Internet access. The motherboard structure of Windows tablet computers is more like a portable laptop computer. Some manufacturers will also launch versions that support cellular networks. However, even ordinary versions of Windows tablet computers can be connected to 4G network cards through a universal USB interface.

　　They are all tablets, but they have different uses. Of course, with the continuous expansion of WiFi hotspot coverage, it is also very convenient to share hotspots with smartphones for tablet computers to access the Internet. Therefore, whether there is 4G Internet access does not make much difference to ordinary tablet users. Mainly used for business purposes. The demand is relatively high.

　　The data volume of Android and IOS systems is small, so the speed and capacity requirements of flash memory are much lower than those of Windows systems. Today, the RAM capacity of mainstream Android and IOS tablets is 4Gb, which is enough to cope with it calmly, while the mainstream 8Gb memory of Windows tablets may not meet all software requirements.

　　The different usage requirements make the screen size distribution of the three major tablet systems different.

　　They are all tablets, but they have different uses. A detailed comparison of tablets of the three major systems.

As for Android and Windows tablets, because there are many brands, the screens of high-end brands basically use IPS, and the display effect is also good. However, for some low-positioned models, the screen is the area with the most serious cost reduction, which can be said to be a mixed bag.

　　Although the tablets of the three systems can be equipped with external keyboards, styluses and other accessories. However, due to differences in hardware and systems, the usage scenarios and accessory requirements are also different. They are all tablets, but they have different uses. A detailed comparison of tablets of the three major systems. Android and IOS tablets are mainly operated by finger touch, but the touch screen of IOS tablets is more accurate, and some users will also configure Apple Pencil for drawing. The most common accessories for Windows tablets are external keyboards, mice and styluses, and their usage scenarios are similar to laptops.

　　Strictly speaking, among the three major system tablets, only Windows system tablets can meet traditional office needs, and it is also more in line with users’ usage habits of office computers. Let alone hardware performance, at least it can work like an ordinary laptop. They are all tablets, but they have different uses. Detailed comparison of tablets of the three major systems. For individual users, if you want to choose a tablet for audio-visual entertainment, you can give priority to choosing from the two major camps of Android and IOS systems, and try to choose a large-size screen version. Because as the screen of the mobile phone becomes larger and larger, the practicality of the small-screen tablet is not so high. And if you want to buy a tablet suitable for office needs, even if it is only used for light office scenes such as processing documents and pictures, it is recommended that you choose a Windows series tablet.
