Ask for help about the quality difference between pixels and photos! ! !

Q: Is it true that the photos taken by mobile phone pixels are very different from my own?

A: There will definitely be a difference. There are all kinds of cameras. As for whether it is "huge", there are many influencing factors. If you mean distortion or something, it may be because the lens distortion is not well controlled. It has nothing to do with pixels, mainly if it is color or something, it is also a lens. If the problem of clarity is related to pixels, attention is there, not inevitable. Another important thing is the size of the photoreceptor.

Q: For example, 320W pixels, what are the auto-focus and 26 times digital zoom functions? The shooting effect is not so good, which is terrible for me ... Why? Is it because the pixel resolution is low?

A: As mentioned above, a camera with a good feel needs these points:

1. Large-size photosensitive elements (digital cameras refer to CCD or CMOS, and film cameras refer to film). )。

If we are referring to electronic photosensitive elements (film is a chemical photosensitive element), another important factor is resolution. Note that the resolution here is not just pixels, but only the ability to process optical signals. It is not a standard title, but you can understand that the stronger the ability to process optical signals, the better.

In addition, from the perspective of image quality, the most decisive factor is the size of the photosensitive element. If you want to make it clear, I'm afraid you have to start with pinhole imaging. You don't necessarily like it, do you To put it simply, just look at the sizes of mobile phones, professional cameras and large and medium format cameras (I don't know if you have seen them). Although it can't be said that the bigger the camera, the bigger the photosensitive element inside. The photosensitive element of a large format camera is as big as a book. Look at your mobile phone again. It's just a big one. Is it too tired for a photographer to carry such a heavy machine all day? Just to look handsome and professional, or to abuse yourself, or to exercise ~ hehe!

Second, high-quality lenses.

On the premise that the size of the photoreceptor remains unchanged, the lens plays a decisive role in the quality of the photo. I don't need to say more about this.

There is no mention of pixels here, because pixels cannot determine the quality of a photo, but pixels can determine the output effect. For example, the standard film for your pixel is 7-inch film. As long as you make a 7-inch film, the pixels will not affect anything, which is the most perfect effect. At this point, any camera makes no difference. You have to make a 12 inch film with 7 pixels. Can you do it? Yes, but there will be some influence. Pixels only make sense at this time. Other times it doesn't make any sense.

Let me give you a simple example. You got a beautiful desktop, and you are satisfied with the picture quality. Your desktop is very big. Let's calculate, according to your desktop is 1280* 1024, then the picture you think is very satisfactory is only 13 10720 pixels, which means only 13 10000. You're angry, fuck. Please look at the two reasons I mentioned above. People may have taken it with a professional camera, with a large format and a great lens. Don't say 13 10000. If people print a picture of 600*800, that is, 480,000, the picture quality will be better than your 5 million. I don't know if I understand.

Q: If a person looks in the mirror (an ordinary mirror is not like a haha mirror ...-), is the person reflected in the mirror a true portrayal of a real person?

Answer: The true nature of human beings is three-dimensional, and the mirror shows this true nature on the plane in the form of reflection. If you compare yourself in the mirror with the selfie, the mirror is definitely more real than the selfie, and any lens of any camera can't achieve this effect. As for the name, please look at the next question.

Q: Why can't you get the effect of how you look in this mirror with any photo?

A: Because, before the alien invasion, under the current development situation of human beings, for human beings, the best and most powerful photosensitive element on the earth is the human brain visual processing system (health), and the best and most powerful lens on the earth is the human eye (health). This cannot be surpassed, and the optical system developed by human beings can only approach this perfection. It's like a computer can't keep up with the human brain.

Q: I also want to know why the photos taken in front of the mirror are so different from those taken directly.

A: As mentioned above, there will be differences, but using a good camera with a good lens and mastering good photography skills will narrow this gap. There must be some good photos in this world.

Here you are: Having said so much, I believe you won't ask this question for no reason. You should be dissatisfied with the things taken by your mobile phone. Nowadays, mobile phones use wide-angle lenses, so don't be too close to the subject when shooting. Try to avoid distortion and take pictures when the lighting conditions are good, which can be improved to some extent. Many mobile phones can also make good movies. Make yourself comfortable. This thing does not need to be too demanding.

I am exhausted. I don't know if you understand. If you don't know anything, ask again.
