How to take pictures of buildings with a fisheye lens
When using a fisheye lens to shoot a building, you can use its distortion feature to create an effect to compose the scene. Because of its wide focal length, it is often possible to combine the elements behind it, emphasizing the lines in the composition to create an expressive architectural photo. It could shoot landmark buildings from a new angle. The fisheye effect would distort the scene, presenting a very exaggerated bending effect, thus creating a different visual experience. In addition, when shooting buildings, you must know how to use light. In the morning, you can shoot with the light to illuminate the details of the building. The side light helps to express the three-dimensional sense of the building. If the line of the building is more beautiful, you can reduce the exposure and shoot at a backlighting angle. Silhouette techniques can be used to strengthen the line structure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the lens of the camera lens?
Based on context alone The lens of the camera lens was made up of many different types of lenses. This included a concave lens, which had a thick middle and thin edge structure. It had a converging effect on light, which helped to focus the light on the imaging plane, making the image clear. There were also concave lenses, which were thin in the middle and thick at the edges. They had a diffusing effect on light and were often used to correct aberrations. In addition, there were also aspheric lenses. These lenses were not the traditional spherical shape. They could better correct aberrations, improve image quality, and reduce image distortion and blurring. They were widely used in modern camera lenses. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
camera lens
A lens was an optical component composed of two concentric spherical surfaces surrounding a transparent medium (such as glass). It was an important component of a camera lens. It was composed of different focal lengths, lenses, and segments. Its main function was to form images, gather light, and obtain a parallel light source. It could bend and refracted light. Different focal lengths of the lens and the use of optical methods could change the perspective effect of the picture. A good lens could make the images and images clearer and more delicate. The lens of a camera could be divided into two categories: a concave lens (thicker in the middle than the edge) and a concave lens (thinner in the middle than the edge). In surveillance cameras, there are many different specifications of lenses, such as lenses with different angles (such as 9 degrees, 15 degrees, 30 degrees, etc.), different diameter, different lamp beads (such as 3030 lamp beads, 3535 lamp beads, etc.), and there are differences in materials, processing technology, and imaging effects. Some were made of optical-grade PC material and manufactured through high-precision aspheric optical processing technology. They had the characteristics of uniform light spots and no dark corners, which could effectively improve the image quality and make the camera better in different scenes to meet more needs. In addition, there was also the emerging technology of superlens technology, which used traditional semiconductor processing technology to build nanostructures on a flat surface to create lenses. This lens was very thin, only a few hundred millimeters thick, about twice the thickness of a human hair. It could also integrate the functions of multiple curved lenses into one device, helping to solve the problem of space constraints. It might bring new development directions for camera lens technology. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera lens changed to a projection lens
Some data showed that the telephoto projection could be used to change the camera lens into a projection lens, and a size image could be projected at a distance of 1.5 meters. He could also use a flashlight as the film's back light and a Nikon lens as the projection lens to make a simple projector and project the reverse film on the wall. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera lens is expensive
In the field of photography, expensive lenses had their value. Generally speaking, more expensive lenses had higher performance in terms of optical quality, workmanship, and performance. For example, in the field of medium and long focal length lenses, Canon's RF70 - 200mm f/2.8L IS USM was priced at 16999 yuan, and the Sony70 - 200mm F2.8GM OSS II was priced at 18999 yuan. These lenses were expensive, but they could provide better imaging results, excellent focusing performance, and good durability on their respective cameras. However, with the changes in the photography market, the relationship between price and value did not completely follow the traditional principle of "you get what you pay". In the micro-monocle era, although some high-end lenses had improvements such as quieter focusing, better design, and improved electronic functions, compared to similar lenses in the DSLR era, users felt less about the improvement in optical quality, but the price generally rose. Some of the affordable entry-level lenses, such as the 50mm f1.8 lens, were no longer as affordable as before. Branded lenses of this size were even hyped up to three times the release price. 24 - 105mm f4 or similar lenses were nearly twice as expensive in the micro-single era as in the single-lens reflex era. Although the optical quality had improved, there was no particularly huge breakthrough. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The lens and camera interface
The lens and camera interface was a component used to connect the lens and the camera. Suzhou Ouka optical instrument factory specialized in the production and development of a camera interface, this interface can be connected to different brands and models of lenses, so that the camera can be used normally. There are many types of industrial camera cable ports: - **USB port **: It is a commonly used port for digital cameras. It can directly output digital image signals. USB was the full name of Universal serial bus. The interface was 4-pin, including 2 power cables and 2 signal cables. There were different versions of USB. The early USB2.0 interface was convenient and widely used, but the transmission rate was slow (480Mbit/s), the communication distance was short (5m), and the band width was mostly used for image transmission (80%). The transmission required the CPU to participate in management and consumed a lot of resources, and the interface was unstable. USB3.0 added two sets of data lines on the basis of USB2.0, which were backward compatible. The transmission speed was increased to 4.8Gbit/s, and the communication distance was extended to 10m. However, the transmission distance was still relatively short. USB interface cameras were easy to use and had a wide range of ports. They were widely used in microscopes, scientific research experiments, portable equipment, and other industries. At present, USB Type Micro-B ports were the mainstream on industrial interface cameras. In the future, USB Type C ports might be popularized. - ** IMEE1394 (Firewire Interface)**: It is a high-speed serial bus. It supports hot swapping, real-time data transmission, and uses a bus structure. It is widely used in the industrial field. It has good protocol and coding methods, and the transmission speed is stable. The 1394a's maximum transmission speed was 400mps, and the 1394b's maximum transmission speed was 800mps (3.2mps was relatively rare). Its interface was divided into 4-core and 6-core. The 4-core contained two pairs of data cables, and the 6-core had a set of power cables in addition to the data cable. This interface did not require a controller and could be used for peer-to-peer transmission. The 1394a's maximum transmission distance was 4.5 meters, and the 1394b's transmission distance was usually 10 meters (100 meters, 100 Mbit/s, when the data rate was reduced). However, the interface's penetration rate was low and it had been slowly eliminated by the market. - **Camerlink interface **: A digital image signal communication interface protocol introduced by the Aia Association. It is a serial communication protocol that uses the LVVS interface standard. It was developed from the Channel Link technology, adding the transmission control signal and defined the relevant transmission standards. The protocol used the MDR - 26-pin connection or the SAR- 26-pin connection, which had high speed (up to 6400Mbps), strong anti-interference ability, and low power consumption. However, it required a separate CameraLink interface, which was not portable, expensive, and rarely used in practical applications. - ** Gige Giga-bit ether interface **: created and promoted by Aia. It is a camera interface standard developed based on the Giga-bit ether communication protocol. It is suitable for industrial imaging applications. It can transmit uncompressed video signals over the network and can use low-cost cables to transmit images over long distances. In addition, in the field of machine vision, other data transmission ports were also developed: - **CoaXPress (CXP) interface **: launched in 2008, supports high-speed imaging applications, uses 75 Omega coax cable, supports data transmission speed of up to 6.25Gbit/s per channel, and can increase the transmission rate of multiple channels. Each cable can provide up to 13W of power. It requires the "device" and "host" to support the GenICam camera programming interface. However, the cost of installing multi-channel cable components and frame clips on a single-channel coax cable increases rapidly. - **CameraLink interface **: In 2000, it was launched by Aia Association and gradually upgraded.（2.04Gbit/s）、Medium (5.44Gbit/s) and Deca/Extended (6.8Gbit/s). Base uses an ADC- 26 pin, medium/full requires a second cable to double the capacity, Deca/Extended can transmit up to 6.8Gbit/s data, and like the CXP interface, it requires an image acquisition card that is compatible with the CameralLink power supply (PoQL) standard for power supply. It lacks error correction or resend functions. The cable setup was expensive and troublesome. - **GigE Vision standard interface **: It is managed by the Aia Association and allows the use of existing low-cost ether cables, connections, switches, and other components. Copper cables can transmit image data up to 100 meters away, and more data can be transmitted through the switch and optical fiber adapters. It has the potential to create different network topologies. Each camera can be placed on the network independently through an IP address. It can be viewed, controlled, and monitored from any PC on the network. However, the maximum 115mb/s has limitations for certain applications. However, NBUSE-T technology could increase the band width within its framework. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
