has a wide perspective and a short range of recent features, It also serves as a useful macro-head function when paired with a high pixel model. 　　Second, fixed-focus high quality 35mm out of the noble Fixed focus lenses used, use zoom do not have too big obstacles, but the habit of using the zoom after the fixed focus is not necessarily used, because in addition to the difference between the focal segment, fixed focus lens quality and large apertu

person will become an amplifier in the future.The organization of the focusing lensA lens, which can be focused using the whole Mirror Group movement, can also be used to design one or several lens movements to achieve the focus; For convenience, most lenses are the latter way.The RZ67 is an example of the overall focus of the moving lens.Mamiya RZ67Historically there was a unique Contax AX, which used the aforementioned point, although the manual fo

two chips support both high-speed USB interfaces, and the product performance and speed will be excellent, it is mainly used for high-end cameras. For example, Moxi electronic night e PC1300ID camera uses the EM2700 chip, in order to meet the excellent video effect, the transmission speed is also well guaranteed. Sonics102P. Sensor We all know that sensors are divided into CCD and CMOS. Why do most cameras use CMOS instead of CCD sensors with better performance? The cost for cameras using CCD

transmission speed of USB interfaces is much higher than that of serial ports and parallel ports, therefore, the current market hotspot is the USB interface digital camera. The following mainly refers to the digital camera with USB interface. How cameras work The working principle of the camera is roughly as follows: the scene is projected to the image sensor surface through an optical image generated by the lens (lens), and then converted to an electrical signal, after A/D (modulus conversion)

"TOC" summary For the current VR technology, the effect of settling the mud chamber is presented.① relies on Unity3d to build 3d environment② rely on panoramic images or panoramic video to achieve panoramic results here is not the first method, mainly say how to use a fish eye camera or panoramic camera to get our VR to use the 360 degree of pictures and videos before we know, we need to shoot skills, And some of the camera techniques used to do some research.get to the point. Take our curiosity

on a wall, where one person is holding a knife, or there is a fruit basket ornament on the wall of a house, and there is an apple in the basket. Never allow a push/pull lens to become a conventional lens, especially when there are many objects in the lens, and these objects must reflect the sense of depth of the scene. The push/pull lens is stiff and looks more contrived. They'd better use it to show the details of an object or the size of the object in contrast to the objects around it. This

This section explains how to predict the type of contact lenses a patient needs to wear.1. Use decision trees to predict the general flow of contact lens types(1) Collection of data: Provided text files (data from the UCI database)(2) Preparing Data: Resolving tab-delimited data rows(3) Analyze data: Quickly check the data to ensure that the data content is parsed correctly, using the Createplot () function to draw the final tree diagram(4) Training a

. Second, create components Step 1 Create a new graphic symbol: The Create New Symbol dialog box opens by executing the new Symbol command (shortcut key Ctrl+f8) under the Insert menu. In the Create New Symbol dialog box, enter the name of the component as glasses, behavior, select the radio button in front of the graphic, and then click OK. Step 2 into the component edit State After creating the component, the edit stage of the animation has been switched from Scene 1 to the edit state of the "

carried around the camera from the Upper Shell. the camera is like the eyes of a mobile phone. In order to ensure a good shooting effect, the camera's front lens must be well sealed to prevent dust or foreign body from entering the line of sight, we use foam to separate the lens from the inside of the chassis, while the outside is stamped with a transparent lens. To ensure good light transmission and wear resistance, the camera lens is made of glass and silk screen at the bottom, the purpose of

term refers to the use of digital image editing software to polish, adjust, and edit images, similar to the dark room in the film era. Digital zoom)A scaling mode. After taking a photo, the camera crops the image or adjusts the image size. The most efficient scaling option is optical scaling. See "Optical scaling ". Double join painting (diptych)Use one of the two pictures in one image. See "Sanlian painting ". Directional Light)Light from a specific direction is called a directional light, suc

I recently saw some discussions about focal lengths in the forum, so I want to talk about the focal lengths. I hope it will be good for you. If any, please note. The focal length of the camera lens is a very important indicator of the lens. The length of the lens focal length determines the size of the object to be imaged on the imaging medium (film or CCD, etc.), which is equivalent to the scale of the object and the image. When shooting a shot of the same distant target, the camera focal len

Fuselage Motor: not supported Nikon D5100 Parameters The camera is a new entry-level digital SLR camera in 2011 that is ideal for first hand use. And this machine uses Nikon D7000 in the CMOS chip, imaging quality is much better than the original D5000. 1, fuselage features: APS-C specifications Digital SLR 2, Operation mode:

Know "wide-angle lens" and "super Wide-angle lens" In general, the 24mm is already a wide-angle lens (Aps-c is 18mm) under the full picture allows you to incorporate a lot of landscape content into the photo, but there is another, more wide-angle lens that can reach 16mm (full width) or 10mm (APS-C), and these lenses are "super wide-angle" ( ultra-wide)! For landscape photographers, the wide-angle lens is useful, but the more useful is the "super wi

Let's use the graphic method to explain the example below. Ideas:1. The Fish Eye Magnifier is composed of several tapering circles;2. So that each circle to mask a larger picture to achieve, inside the small round mask larger than the picture, outside the large circle mask smaller picture;3. There is also a final important step is "focus", because the picture is growing, so the mouse is a point of the small image may be the head, and for the larger picture may be out of the field, then show the

size: 200*200, the instance name "Ball", the registration point in the center; Mag4.jpg 2. Fish Eye magnifying Glass is a number of gradually small circle composition, so that these circles as lenses, overlapping together, while imaging, the number of circles (lenses), the more detailed imaging effect, the figure of 3The code is as follows:var count:number = 3;Number of copies of Circle (

Pictures of the line crooked distorted, or too dark around, this is not entirely a camera or photographic technology problem, but the lens image deformation and the natural physical phenomenon of corner loss, as long as the lens correction in Photoshop Lightroom 4.2, you can immediately automatically identify the lens model, To carry out deformation and dark angle correction, but also support the major brands of the hot shots, now come to try it! Camera lens, is composed of many different shape

The dual-tube telescope is a useful astronomical observation tool. You can use it to watch a game, concert, or birds in the sky. You can also use it to enjoy the galaxy, the crater on the moon, several satellites around Jupiter and countless stars 2 million light years away. Many people mistakenly think that the dual-tube telescope is not used for astronomical observation. In fact, it is a favorite tool of many senior astronomical observers. For beginners, It is the entrance to astronomical obse
