What do you mean by shifting axes?

Question 1: What is the axial shift effect? Shift-axis photography, that is, shift-axis mirror photography, generally refers to the works created by shift-axis lens, and the photos taken are particularly like miniature models. The function of shift lens was originally used to correct the perspective problem caused by ordinary wide-angle lens.

Question 2: What is axial photography? Shift-axis camera lens is a kind of camera lens that can adjust the perspective of the captured image or focus the whole area. Moving axis photography needs a special moving axis lens to adjust the distortion when shooting buildings, but it is usually not used. The main feature of axis-shifting camera lens is that the main optical axis of the whole camera lens can be translated, tilted or rotated on the premise that the plane position of the camera body and the film remains unchanged, so as to adjust the viewing angle of the shot image or focus the whole area. The reference clear image field of the camera lens with shifting axis is much larger, which is to ensure that the camera lens can still get a clear image after its optical axis is translated, tilted or rotated. Axis-shifting photographic lens is also called "TS" lens ("TS" is English "Tilt &；; The abbreviation of "shift", namely "oblique shift"), "oblique beat", "shift beat" and so on. After the single-lens reflex camera adopts the shifting camera lens, this single-lens reflex camera also has the function of controlling the perspective by adjusting the leather cavity of the large-scale combined camera, thus expanding the application range of the 35mm single-lens reflex camera. In the field of professional photography, the lens of shifting axis camera plays a considerable role. The lens of shift axis camera has two main functions: one is to correct the perspective deformation of the subject; The second is to focus on the whole area of the subject, so that the far and near subjects in the picture form a clear image.

Question 3: The "shifting axis photography" on the mobile phone is like this. What does shifting axis photography mean? Shifting axis refers to a special shooting technique, which is usually done by shifting axis lens. This lens has a movable joint, which can make the lens move left and right. The shot image will have a special effect of blurring up and down and clear middle horizontal band, which can increase its realism and three-dimensional sense when used to shoot miniature models.

Question 4: What is the meaning of shifting axis photography in Xiaomi's likeness? In the era of the popularity of smart phones, 800W pixel mobile phones are not excellent. Some friends may often complain, why is the 800W shot so effective? Why can the 500W pixel of someone else's mobile phone have such an aesthetic effect? It is not that the products at the same stage are not representative at all, let alone comparable. The photos taken by the same camera with different technical parameters are also very different.

Personally, I think we should pay attention to some skills when taking photos with mobile phones, not automatic gears. Just press the shutter casually. Taking pictures is actually a meticulous job. Many times, seeing a photo in a circle of friends may get praise from many friends. In fact, it may take you a long time to take such artistic photos, but it is also possible that the ambient light is very good at the moment. Just take a photo and a beautiful moment will appear. Even so, it is inseparable from your careful observation. I wonder, isn't there a careful observation heart and a pair of beautiful eyes behind that good photo? Taking photos is a pleasure, so you will find that the photos you take are actually good!

The following are photos taken by Redmi and me. I usually set the parameters manually when shooting. Turn on the camera-Switch to expert mode-Photo size (8 million)-Photo quality (surprise)-Focus mode (automatic) "Macro can be set"-Default settings of other parameters-Return-Call up the grid (convenient for composition, generally focusing on 2/3 of the grid, the golden section commonly used for taking photos)-The light is dim and increases to the right) -ISO (generally at/kloc)

Question 5: What does the shift lens effect mode in the camera mean? How to operate? Thank you. Axis-shifting lens is a special lens in Canon EF lens that can realize tilt angle and offset function. The so-called TS-E in the lens name is the initial combination of tilt, displacement and electromagnetic aperture. Use the tilt angle and offset function to rotate the lens to various angles and positions, which can move the focal plane or compensate the shape of the object. It is very common for large-format film cameras to take shift-axis photography by changing the position relationship between the optical axis of the lens and the imaging plane, and the shift-axis lens that can be realized on a 35mm-format camera can be said to be a special lens for professional photographers. However, due to the recent expansion of the real-time display shooting function, it is easier to operate the shift lens. As long as you keep in mind its basic principle, you can use it flexibly by constantly trying to operate it, and you can also experience unexpected effects that other lenses can't bring. I hope it works for you.

Question 6: What is the popularity of shifting axis photography? Miniature model bar

What axis-shifting photography wants to express is to make the real scene into a miniature model and make it an illusion, like the feeling of an artificial city.

Hope to adopt. Thank you.

Question 7: What is a shift camera? Shift axis is a lens, which corrects the deformation of tall buildings in the central projection by moving the optical axis of the lens.

Question 8: What is the specific function of the axis-shifting lens? Architecture, landscape, advertising ... are all suitable for photos to correct the perspective relationship.

Question 9: What are the shift lens and paraxial lens in SLR lens? Their respective advantages are generally that buildings stand on the ground. In order to capture the whole picture, the camera should be tilted slightly upward. Because the common part of the building is close to the upper part and far from the upper part, the connection effect of "big bottom and small top" will be adopted The lens itself is not deformed, and the reason for this phenomenon is the perspective relationship. The axis-shifting lens can be adjusted to make the vertical line vertical and parallel.

The structure of axis-shifting lens is different from that of ordinary lens, and the middle can be bent and staggered.

So as to realize the simulation of Shaughnessy's law of large format camera (I know some words may not be understood, but you can search Baidu. If you talk about it all here, you can write a book, if you are interested in the principle.

Let's talk about the effect first

In addition to adjusting the perspective of the building (this is only a primary function, and most people who know about shifting lenses will stop there), moving the lens can also control the depth of field. In principle, according to Chaath's theorem, it can make the grass under your feet clear all the way to the farthest tower head, which is really clear and within the focus range.

You can also let the person in front of you, the left half is clearly focused, and the right half is empty outside the depth of field.

Now some single camera and small DC have this simulation function, and some are called toy mode or model mode.

That's just a simulation.

In fact, the axis-shifting lens used in 135 camera is affected by the bayonet, flange, image field and other factors, and the axis-shifting effect is much worse than that of large-format camera.

Paraxial, to be precise, there is no such name as paraxial lens.

Only paraxial cameras.

Paraxial camera is a kind of camera, which is different from the popular SLR, and is called parallel name with SLR, double reflex and newly invented single electricity.

The characteristic of paraxial camera is that the light path of framing is different from that of shooting lens, and it is next to the lens.

So it's called a paraxial camera.

Unlike the double reflex, this camera has no reflector, and the viewfinder is not called a lens, but is composed of some optical lenses. The early Seagull 205 and the Leica M series mentioned upstairs are representatives of this kind of camera.

Paraxial camera is characterized by small shutter vibration.

But there is parallax when shooting, especially at close range.

Question 10: What is the significance of moving axis lens? Moving axis lens is a very important special purpose lens, which plays an irreplaceable role in still life shooting, landscape shooting, architecture shooting and portrait shooting.
