"Your background is so fake!" How did the real photo become five -haired special effects?

"Your background is too fake ..."

"Fake? You talk again!"

Recently, the UP main territory Alemu staged a tug -of -war with netizens. Under the beautiful Xinjiang scenery, the dark Alimu was as if it was pushed up.

Why is it so violating it? ｜@b/Bilibili

Netizens couldn't believe their eyes, and they said "your background is too fake." Ami, who is not convinced, began to prove his innocence.

In order to prove that the background is true, he threw the bucket into the water with a big hand, and asked the audience while throwing it.

Who's almost lost? I don't say ｜@我 木//Bilibili

Before passing the pink blue pink blue creek, he picked up a stone and threw it into the water, and saw the stone stirring the waves, and then proudly said to the audience, "It's not a false background."

It's not that I don't believe you, it's you really look too fake ... |@不 力 力/bilibili

The bees who did not mess with anyone were pinched by Alimu and then released, just for the affirmation of a netizen.

The background is a green curtain? ｜@b/Bilibili

Although the background and people are indeed true, why does it seem to be wrong? It looks like p?

Fake ever -changing

Ali Mu's videos each have their own "false". In order to figure out where there was a problem, we chose a very representative "rapeseed field" and tried to make some changes.

The easiest way to make the video "true" is the screenshot. After cutting off the upper part of the picture, it looks like more than half.

In the original picture, Alimu raised his head, and at the same time, one hand was drawn on the edge of the picture. This action looks very much like a selfie. People who have taken selfies must have felt the pain of "hate their own hands": the face occupies too much in the picture, so that they can't tolerate more pictures.

The perspective of this "selfie" instead of Ami Mu, you will feel that the peaks in the distance can be strange -theoretically, selfies can only accommodate rapeseed fields. How can there be mountain peaks? What?

In fact, watching the video will find that Alimu did not take another hand to take a selfie, which may be taken by others to help. When you see both hands in the picture, you feel that the composition of this picture is more reasonable.

It seems that the unreasonable perspective is easy to confuse the human brain, such as why the famous "pigeon is so big". But re -imagine the location and perspective relationship of the shooting. When you look at this picture from "near the big far away", why the pigeons are so big.

Re -reader: Why is the pigeon so big pigeon so big pigeon so big?

However, this did not make Alimu's picture completely "real". Ami Mu's skin color must also take a certain responsibility for the "false" of the video. In these videos, the brightness and color saturation of the background are mostly high, but a dark matte handsome guy suddenly appeared in the bright background. Under the source of light.

Slightly adjust the skin tone of Ami Mu, the real sense of this picture can be added.

In addition, the platform's compressed picture quality makes people look confused, as if the person who is pulled out of other low -quality materials. We add a little sharpness to make people know more clearly and can be a little bit.

We have done our best here, but there is still a problem: Ami Mu's protruding earlobe makes people feel that the photo is not cleaned ... you work hard to make up a ear.

"Fake photos", it's easy to take pictures

Shadow and perspective

If you want to take some "fake photos", the shadow and perspective are two natural props.

The brain will treat a pool of water on the ground as a shadow, allowing people to hang directly in the air.

Or pick a direct sunlight, without shadows will make your photos look fake.

Choose a good angle, you can also have the hanging cat's head. It seems that the cat's head is strangely suspended on the door frame. In fact, the cat hides behind the door frame and exposes his head to meet the owner.

Perfect color

The "fake" of many photos is that it is too perfect. The bright and saturated colors and the full picture that cannot be observed will turn a photo into a painting.

Studies have pointed out that the color of high saturation and high brightness can attract people's attention. Therefore, many mobile phone manufacturers will also choose to make the saturation of the photo a whole, and look at the eyes.

But this saturation is not good. If you see a photo with a beautiful color with high purity, your first reaction will tell you: this is a painting. Excessive saturation will leave the color of the picture away from nature, and the image is drawn out. As the photographer Heather Barnes said: "It is difficult to see solid color in nature, because environmental light will reduce the saturation of color. This is why you must be very careful in the later period, don't make the color too saturated." It shows that it is only local, and we cannot get more details and real information at the shooting scene. This makes it easier for photographers to "make perfect".

Excessive "calculation"

Although we used sharpness to make Alemu's photos more real, in fact, excessive sharpness is also the "culprit" that looks fake.

Although the sharpness will make the overall picture clearer and more impactful, excessive sharpness will also cause white edges to appear on the edge of the objects in the picture, which will make the taste of the object heavier.

In addition, "Calculating Photography" has been launched one after another, of which automatic HDR (High Dynamic Range) function has become indispensable. To put it simply, this function is actually by taking photos under the same scene and different brightness of the same scene, and synthesis through algorithms, so that the overall view of the photo is improved. However, many people find that when the background light is too strong, HDR will forcibly improve the light of the backlight face. This will cause the whole person to be gray, like P going up.

If the sharpness and no shadow, it looks even more proper.
