The ability to take pictures of mobile phones is getting stronger and stronger, and with the inherent portability, even in the professional fields of photography and news, the status of SLR cameras is gradually eroded.

We often relive the beautiful moments recorded by the camera on the mobile phone, but once these photos go to the computer or the big screen TV, it seems that they have not been so "beautiful" on the mobile phone.

Why is the photo taken by the mobile phone very good on the mobile phone, but it is not good to watch it on the computer? Below we will come to answer this question for you.

Screen Resolution

The look and feel on mobile phones and computers is different. The first reason is to let the resolution back computer monitor arm Suppliers.

At present, the mainstream resolution of mobile phones is basically maintained at the level above FHD, even going to 2K or 4K, and the HD level resolution is rarely seen on the thousand yuan machine. The mainstream screen size is maintained at around 6 inches, which means that the displayed pixel density reaches 264PPI, even to the level above 300PPI.

So on the mobile phone, we see ultra-high-definition photo thumbnails, the picture sharpness is higher, the same area has clearer details, and the look is better.

This table lists the current common mobile phone resolutions, FHD and 2K levels are mainstream, and there is such a terrible existence of 4K level.

In contrast to the computer screen, even in the thousands of mobile phones have been used on the FHD screen, there are still many entry-level notebooks still use the ancestral 1366x768 resolution, and even the mainstream desktop display, it is only 1080P level. In Internet cafes, professional studios, you may see the emergence of 4K displays. So, what is their resolution?

From the above table, it is obvious that even the 23.6-inch "small display" with the 4K level has only 195 PPI, which is basically half of the current mainstream smartphone. At present, most mainstream 4K displays are 27 inches or higher, so the pixel density will drop, not to mention those products that only have 1080P level.

Demonstration, non-real screen effect

What are the consequences of a drop in pixel density? For example, in the iPhone 8 Plus and the 21-inch 1080P display, the same size of the picture is displayed. The former shows a pixel density about four times that of the latter, providing a sharpness and detail that is completely out of one level.

Therefore, the photos on our mobile phones look very "poisonous" and very sharp. On the display, they are "paste" to suspect their eyes.

Screen color, material

The second back pot man, the screen color can not run. Due to the different product positioning, the screen material selection of mobile phones and computers is very different.

Zoom in on the phone screen

Mobile phones are devices we can't do every day, meaning we use them in a variety of poses. Walking with a mobile phone, lying down playing with a mobile phone, doing push-ups and side-by-side drama... The viewing angle of the mobile phone screen must meet our needs for color. From all directions, a mobile phone that does not change its color can be called qualified.

Passing the top, the mobile phone screen is also more accurate in pursuit of the screen, not only the sRGB color gamut, DCI-P3 color gamut and other broader color gamut standards have become the standard for flagship mobile phones, whether it is color or color accuracy, Both have reached the current mainstream of display technology.

High color gamut and high precision, mainly due to the development of mobile phone panels, even for thousands of mobile phones, IPS screens are also the products of passing lines, better OLED screens, basically become the mainstream of high-end mobile phone screens, color and contrast performance Needless to say, it looks cool.

The computer is very different. We can't hold the monitor on the bed with the computer. It is more at the computer desk and is viewed at a fixed angle. Therefore, the material of the computer screen does not need to be too good, as long as it looks from the front. No discoloration, no color deviation, basically meet the needs of many people.

iPhone 8 Plus vs Macbook Air screen

And because of the larger size, the computer display is more difficult to achieve a wide color gamut, and the cost is high. The display equipped with DCI-P3 color gamut support is half the price of the ordinary display, so the mainstream notebook and display are in the color display to lose a lot of mobile phones. The photos taken by the mobile phone are placed on top and are naturally gray and heavy.

At present, many computer display screens still use TN material, and even the entry-level 4K display is also used. Although the gray-scale response speed is fast, the biggest disadvantage of the TN screen is that the viewing angle is not good, and the hair color is relatively general, so it is good-looking. Mobile phone photos, unless you use the late software to pull up the saturation, it doesn't look like it.

Mate 10 vs. Macbook Air screen

Comparing the gap between the TN screen and the OLED screen, the black color of the computer is slightly gray, and the red and green colors are not bright enough, while the mobile phone OLED is very eye-catching and can instantly capture the color of the eyeball. However, in many TN screens, the color of the Macbook Air is quite good, that is, the resolution and viewing angle are not satisfactory.

The same photo on a computer and mobile phone is like adding a gray filter? It's not that you can't take pictures on your mobile phone. You should change the monitor.

Later adjustment

After talking about two more realistic back pots, let's talk about some metaphysical things. Why do mobile phone photos feel better than on a computer, mainly due to vendor optimization.

After all, compared with professional cameras, the difference in sensor size is a short-term photo capture performance, which requires us to make some optimizations in the software, and take advantage of the small screen of the mobile phone, so that the viewer's brain thinks: " Hey, this photo is not bad.

Therefore, the mobile phone camera performance is not solely based on the actual ability of the camera. Some thousand-yuan mobile phones want to take pictures and look good. If they are adjusted under their own hardware limitations, they will have quite good results

With software optimization, the hundred yuan machine can also have a mid-level camera level

What to do if the sharpness is insufficient, sharpen it directly, and make the details look sharp. How to do the color is not saturated, come to an AI color filter, let the photos you take on your mobile phone instantly get the praise of “Poison! Dewei! Master! Learn!”. But when you look at the computer monitor, you will find that the transition sharpens the distorted picture, the too saturated color, and the details that are painted into pieces of oil painting.

Conclusion

Why are the photos on the mobile phone very good? It is terrible to look at the computer, and there are both reasons for the computer and the reason for the mobile phone.
