Why is the scene taken by the camera different from what the eye sees?

Theoretically, a picture taken with a digital camera is the same as what the eye sees. However, because the digital camera is optically converted to electromagnetism, it is inevitable that some parts will be lost in the conversion process, and the digital camera has built-in processing software. You can correct the color of **, but this thing depends on your preference.

To put it bluntly, that is, the digital camera helped you with a pre-ps. It's just that it's purely theoretical.

In addition, the difference between the two is also related to the operation when you shoot, such as the shooting mode. The degree of exposure, etc., and the most important thing is the display, but the LCD on the camera is good. It's also a computer monitor.

The ability to reproduce colors cannot be compared with the human eye. This is the same as the fact that the color is inaccurate when printing in color.

I think the first thing is that the human eye is a wide angle, the camera lens is not necessarily a wide angle, and the color of the things that are photographed cannot be exactly the same, after all, there is a present, and it has little to do with pixels, or the film will not be divided into color negative and reversed, the restoration of color is different!

On the camera, the flash settings turn on the red-eye prevention function before shooting**, and you won't have the above problems.

Haha, this is called not knowing the true face of Lushan, only because you are in this mountain.

When taking pictures, the camera and people's eyes see differently.

Because there is a distance between the eyes, what is seen is three-dimensional, and the image seen is the image after "emotional rendering" in the brain. What the camera captures is only an objective reflection, and the brain can only do it after tomorrow if it is to be processed. For example, if you normally stand in one place and look at things around you and look at a wide field of view, you can only take a small part of a photo with your mobile phone, so there is a difference between the camera and the actual appearance of the person.

So far, there is no disregard for the background, only focusing on the target of interest, and the camera can do that. Most of us feel this characteristic of a camera. I've always advised my friends who buy cameras to buy a telephoto lens.

Why, because a telephoto lens can highlight this feature of the camera even more. Friends with 24-70mm lenses hardly have a chance to feel this. With this feature, the camera is destined to always be stronger than the human eye in this field.

Why not emphasize its characteristics?

The charm of a telephoto lens is the greatest pleasure of getting started with photography. It helps us to "subtract", subtract unnecessary parts of the screen, highlight the subject. The fundamental attraction of this type of shooting is that it is different from what you can see.

Everyone who sees ** has to shout loudly: Like!

"There is more to record than the naked eye can see. ""The ability to express continuous infinite subtle levels of imaging. "A camera that goes beyond the detailed description of the naked eye can give the photographer this characteristic.

Relying only on rich details and natural soft horizontal variations can attract the viewer's attention, if you are good at using this kind of detail expressiveness.

In conclusion, most of the advantages of the visual system are that our brains are able to intelligently interpret what the eyes see, whereas the camera only records the original image. Despite this, digital cameras are developing very quickly, and some have developed visual abilities that surpass those of the human eye.

There is only a big difference, because the camera of the camera is flat, so the person who shines out will be a little wider, and the eye is three-dimensional, so the person who sees it will be a little more curved, so the camera and the person seen by the human eye are very different.

The difference is particularly big, because the people in it feel very dull, and their eyes are not focused, but people's eyes see more things and are more colorful.

There will be cases where you can't see clearly, you can freeze the moment for a moment, you can focus on it, you can p the picture, what the human eye sees is ever-changing, and different analyses will be carried out according to different angles.

I believe that many photographers have experienced the scenery they hear with their eyes, and the scenery captured by the camera is the same as what the human eye thinks. How could this happen? Appropriate cognitive abilities.

It is the basis of shooting writing.

General Cognitive Abilities:

Everyone is a different individual, and regardless of the difference in the level of vision of each person's eyes, the whole process of seeing a small ball and producing an image in the human brain is not very accurate, and it will suffer from personal growth experience and psychological disorders.

But the camera is emotionless, it is a mechanical device, so the scenery seen by the human eye is different from the scenery taken by the camera.

Visual Selectivity:

In contrast to the camera, the structure of the human eye is much more complex. The human vision system software is a relatively complex and peculiar system software, which is far beyond the camera to compare. In the process of watching with the human eye, the eyes can quickly switch focus, integrate the resolution of the human brain, and continue to fully automatically strengthen the thinking of excellent things.

The human eye has visual selectivity. Even the most advanced cameras can't match this kind of visual selection, and the camera can only be based on the field of viewing, the spacing of the focal points, and the contrast.

and so on. This is also the reason why the scenery seen by the eyes is not so disorganized, and the scenery taken with the camera is chaotic and disorganized, and there are things that affect the visual results.

Visual Memory Adaptability:

When the audience walks into a low-light room, the human eyes can quickly switch between dark light and gray, and the pupils will constantly adjust to blend in the chromaticity.

The transformation of the left brain.

The whole process is brought together to produce a detailed image. The camera is only a special tool for shooting, it must be manipulated by the photographer, and the emotion granted by photography is the main expression of the photographer's application of modeling design.

Visual Memory Effect:

Human vision has a memory effect - the human brain will compose these fragmented parts of vision into detailed visual impressions. For example, a milky white color under a fluorescent tube will actually turn emerald green, but visual experience will tell you to still think of it as milky white. The visual memory effect is also reflected in the photos taken by the camera, how to see the things that the human eye ignores, simplify the complicated, and highlight the key points in the interface, is a difficult problem that the photographer must think about.

The way a person looks is different from what a camera sees, and shooting is not just a matter of holding down the fast door, but the photographer must give full play to his or her own initiative.

Integrate your own work experience methods, apply the actual effect seen by the human eye to the level of photography, and stay in the interface.

The main reason is that there is still a certain difference between what we see with our eyes and what we take out with the camera, and what we see with the human eye should have a certain beautifying effect, because the focusing ability of our human performance is different from that of the camera.

Because the lens of the camera is flat, and the human eyeball is round and convex, it looks different and gives people a different feeling.

Because the human eye sees an object in 3D and the camera sees a 2D object, it will look very different.

Because there is a visual difference, there will be a certain error in the quality and focus of the camera, which is very different from the structure and design of the human eye.

The main reason is that the retina can be imaged with different sensitivities in different areas of the picture, while the camera uses a sensitivity to image. Therefore, when the sunlight is strong, some pictures with relatively large brightness contrast can be seen clearly by the human eye, and the effect of the camera is that the picture is either too violent or dim.

DSLR cameras. The viewfinder shows the same effect as the image of a sleek DSLR camera. Because of the focal length of the lens.

It is different from the human eye, so the view of the destroyed car in the viewfinder of the SLR camera is not the same as the view seen by the human eye.

The perspective of the human eye, with the full frame.

The 50mm focal length is similar. But it's not quite the same.

The angle of view of a full-frame 50mm lens is similar to that of a full-frame 50mm lens. But the human eye can also use the afterglow to see other scenes. This is the part that cannot be imaged by the lens of a DSLR.

Whereas, SLR cameras are interchangeable lens cameras. It can carry lenses with different focal lengths. The imaging characteristics of these lenses with different focal lengths are different.

Therefore, when a lens with different focal lengths is attached, the state of the object seen in the viewfinder is not the same as the scene seen by the human eye. This is quite normal.

In addition, it should be noted that the state of the scenery seen in the viewfinder of the SLR camera is also different from the effect of the final ......Although the viewfinder of a DSLR camera claims to be what you see is what you get, but the depth of field.

The image effect in the viewfinder is indeed different from the effect after the final film......

If the viewfinder of the DSLR camera is different from the view that you see with your eyes, it is because you have adjusted the framing angle of the finger dismantling it in it. In addition, the distance of their photographs is different from our eyes, so the scenery is also different.

Because of the lens convergence and smaller aperture reflectors, it's different.

1.The camera image is a flat surface, and what the human eye sees is a three-dimensional image formed by two eyes;

2.The angle of view of the human eye is about the same as the 50mm focal length lens of the 135 camera, while the lens with a focal length of about 37mm is used most often by the general camera, so the angle of view or field of view is different;

3.The images seen by the human eye are corrected by the brain, for example, there are some perspective relationships, in fact, the image of the eye is the same as the image of the camera, but the brain will correct it according to general experience, such as taking a low-angle photo of several tall buildings side by side

There are three main reasons for this:

1. The tolerance of the human eye is much greater than that of the camera, so the contrast relationship between light and dark when the human eye sees the still life is much larger than that of the camera.

2. The human eye can immediately and accurately distinguish the color no matter what the light conditions are, but the camera cannot, the white balance of the camera can not completely identify the color in the scene in time, and many times the white balance needs to be manually adjusted, so as to be close to the human eye's perception of color.

3. What the human eye sees is a three-dimensional 3D image, which is a two-dimensional image displayed on a flat surface, which is also an obvious difference between the two visions.

Entry-level SLR framing is generally 95% of the frame. The framing is smaller than the one taken. Quasi-professional, professional grade is 100% seen and photographed as the image.

The framing of a DSLR camera is carried out by the reflection of light from the prism between the lens and the shutter. At this time, the CCD is not working, so what you see is different from what you shoot.

When taking a picture, the prism is reversed upwards (which is also where the name of the DSLR camera comes from), the shutter opens, and the CCD works.

Therefore, the advantage of DSLR cameras is that the life of CCDs is longer than that of non-SLR cameras! Because it has extremely short working hours. Only the moment you take a picture works. The CCD of a non-DSLR camera is used for framing most of the time.

The imaging of the human eye and the camera is different. People who regularly use their cameras to take pictures will see what the human eye sees.

There is a difference between the scenery and the camera, mainly because the image that the human eye can see is an average image, while the camera can only save the momentary image in the process of shooting.

In addition, the human eye will have visual persistence when looking at things. That is to say, after the image disappears, we can still see the existence of the image for a short period of time, and this image will remain for about a few seconds before disappearing. Therefore, what he saw was an average image, and the camera had changed more than a dozen, or even dozens, of images during this time, and there were reticulations.

Compared to a normal camera, the structure of the human eye is much more complex. The vision system is actually a wonderful and complex system, which is far beyond the reach of current cameras.

When people are in various landscapes, their eyes can quickly switch focus, and at the same time, they can automatically strengthen the outstanding things in combination with the judgment of the brain. That is to say, when the human eye looks at the landscape, it will be visually selective. The camera, on the other hand, can only make comprehensive trade-offs based on the focus distance, framing range, and saturation when shooting scenes, so the scenery captured by the camera will always look a little cluttered.

The human eye selectively images landscapes according to their personal preferences. In addition to the difference in the level of vision, when seeing the same scene, the imaging process in the brain will also be different, which will be mainly affected by psychological factors and personal experience. The camera, on the other hand, is a mechanical machine and has no emotion, so there will always be some subtle differences between the scenery it captures and the scenery that people see with the naked eye.
