What does tilt shift mean?

Question 1: What is the tilt-shift effect? Tilt-shift photography, also known as tilt-shift lens photography, generally refers to works created using a tilt-shift lens. The effect of the photos taken is like a miniature model, which is very special. The purpose of a tilt-shift lens was originally to correct the perspective problems that occur when taking pictures with an ordinary wide-angle lens.

Question 2: What is tilt-shift photography? A tilt-shift photography lens is a photography lens that can adjust the perspective relationship of the captured image or focus on the entire area. Tilt-shift photography requires a special tilt-shift lens, which is used to adjust distortion when photographing buildings. It is not usually used. The most important feature of the tilt-shift photographic lens is that it can translate, tilt or rotate the main optical axis of the entire photographic lens while maintaining the position of the camera body and film plane, so as to adjust the perspective or perspective of the photographed image. The purpose of focusing on the entire region. The reference clear image field of a tilt-shift photographic lens is much larger. This is to ensure that a clear image can still be obtained after the optical principal axis of the photographic lens is translated, tilted or rotated. Tilt-shift photography lenses are also called "TS" lenses ("TS" is the abbreviation of "Tilt&Shift" in English, which means "tilt and shift"), "tilt lens", "shift lens", etc. After the single-lens reflex camera adopts a tilt-shift photographic lens, this single-lens reflex camera also has the function of controlling the perspective by adjusting the bellows of a large combined camera, thereby expanding the scope of use of the 35 mm single-lens reflex camera. In the field of professional photography, tilt-shift photography lenses play a huge role. The tilt-shift photography lens has two main functions. One is to correct the perspective deformation of the subject; the other is to achieve full-area focus on the subject so that both near and far subjects in the picture can form a clear image. .

Question 3: When you take a photo with “Tilt-Shift Photography” on your mobile phone, it looks like this. What does “tilt-shift” mean in tilt-shift photography? Tilt-shift refers to a special shooting technique, usually done through a tilt-shift lens. This lens has a movable joint that allows the lens to move left and right. The captured image will have a special effect of blurring the upper and lower edges and clear horizontal bands in the middle. , when used to take pictures of miniature models, it can increase their realism and three-dimensionality.

Question 4: What is the meaning of tilt-shift photography in Xiaomi portrait? In the era of popularization of smartphones, mobile phones with 8 million pixel configuration are not outstanding. Some friends may often complain, why is the 8 million pixel camera taken with 8 million pixels? Such an effect? Why can the 500W pixels of other people’s phones have such beautiful effects? It’s not that products at the same stage are not representative or comparable at all. The photos taken by the same camera with different technical parameters are completely different.

Personally, I think that taking pictures with a mobile phone requires some skills. It is not an automatic shutter, just press the shutter button at will. Taking photos is actually a delicate job. Many times when you post a photo on Moments, you may get a lot of likes from your friends. In fact, it may have taken you a while to take such an artistic photo, but It is also possible that the ambient light is very good at the moment, and a beautiful moment appears just by taking a photo. Even so, it is inseparable from your careful observation.

Let me ask, is there not a heart of careful observation and a pair of eyes that discover beauty behind that good photo? Taking photos is a kind of fun, so you will find that your photos are actually good!

The following are the photos I took with Redmi. When shooting, I mostly set the parameters manually. Open the camera - switch to expert mode - photo size (8 million) - photo quality (surprise) - focus mode (automatic) "Macro can be set for macro shooting" - Default settings for other parameters - Return - Bring up the grid (convenient for composition, the general focus is at 2/3 of the grid, the golden section commonly used for taking pictures) - Exposure compensation (strong light goes to the left) Lower, increase to the right when the light is darker) - ISO (generally between 100-400, low sensitivity and less noise, use less than 800, 1600 has serious noise, affecting the quality of the film, use with caution) - White balance (generally automatic, Or set manually according to ambient light) - Scene selection (automatic)

Question 5: The tilt-shift lens effect mode in the camera is What's the meaning? How to operate? Thanks! The tilt-shift lens is a special lens among Canon EF lenses that can achieve tilt and offset functions. The so-called TS-E in the lens name is a combination of the initials of Tilt (tilt), Shift (eccentricity) and Electro-magnetic Diaphragm (electromagnetic drive aperture). Use the tilt and offset functions to rotate the lens to various angles and positions to move the focus plane or compensate for the shape of the subject.

It is very common for large-format film cameras to perform tilt-shift photography by changing the positional relationship between the optical axis of the lens and the imaging surface. However, the tilt-shift lens that is implemented on 35mm format cameras can be said to be a lens specially designed for professional photographers. However, due to the recent expansion of Live View shooting capabilities, tilt-shift lenses are easier to operate. As long as you keep its basic principles in mind and keep trying the operations, you can use it flexibly and experience unexpected effects that other lenses cannot bring. Hope it is useful to you

Question 6: What is tilt-shift photography in a layman’s terms? Miniature model

What tilt-shift photography wants to express is to make the real scene look like a miniature model, and make the real scene look like an artificial city, as if it were an artificial city

Thank you for your adoption

Question 7: What is a tilt-shift camera? A tilt-shift lens is a lens that corrects the deformation of tall buildings on the central projection by moving the optical axis of the lens.

Question 8: What is the specific function of a tilt-shift lens? Architecture, landscape, advertising... Suitable for photos that need to correct the perspective relationship

Question 9: What are tilt-shift lenses and rangefinder lenses in SLR lenses? What are their respective advantages? Generally, when shooting buildings, you stand on the ground. To get the full picture, the camera needs to be tilted slightly upward. Since the parts of the buildings are closer to each other and farther away from each other, it will produce a convergence effect of "large at the bottom and small at the top". The lens itself is not deformed. The reason for this phenomenon is due to the perspective relationship. The tilt-shift lens can adjust the top and bottom to make the vertical lines vertical and parallel.

The structure of the tilt-shift lens is different from that of ordinary lenses. It can be bent and staggered in the middle.

In order to achieve the Sandburg's law of simulating large-format cameras (I know some words may not be understood, but you can check it on Baidu. If you explain it all here, you can write a book. If you are interested in the principle words).

Let’s talk about the effect.

In addition to adjusting the perspective of the building (this is only a rudimentary function, and most people who know about tilt-shift lenses stop here), moving the lens can also control the depth of field. In principle, according to the Shah's theorem, it can make the grass under your feet all the way to the farthest tower head clear, truly clear, and all within the focus range.

You can also make the left half of the person in front of you clear in focus and the right half blurred outside the depth of field.

Nowadays, some single-camera cameras and small DCs have this similar function, and some are called toy mode or model mode.

That's just a simulation.

In fact, the tilt-shift lens used on 135 cameras is affected by factors such as the bayonet mount, flange, and image field. The tilt-shift effect is much worse than that of large-format lenses.

Rangefinder, to be precise, there is no such thing as a "rangefinder lens".

Some are just rangefinder cameras.

Rangefinder camera is a type of camera, which is different from the popular SLR. It is called in parallel with SLR, twin reflex and the newly invented single camera.

The characteristic of rangefinder cameras is that the light path for viewing is different from that of the shooting lens, and is on the side of the lens.

So it is called rangefinder camera.

Unlike a double-lens reflex camera, this camera does not have a reflector, and the viewfinder cannot be called a lens, but it is composed of some optical lenses to form a viewfinder. The early Seagull 205 and the Leica M series mentioned above are representatives of this type of camera.

The characteristic of rangefinder cameras is that the shutter vibration is very small.

However, there is parallax in framing, especially at close range.

Question 10: What is the significance of the tilt-shift lens? The tilt-shift lens is a very important special-purpose lens, which plays an irreplaceable role in still life photography, landscape photography, architectural photography, and portrait photography.
