different manufacturers. When it is difficult to choose, we recommend that you refer to the following three standards:
1. Shape and feel. A machine that you don't like is uncomfortable.
2. pixels. Currently, the mainstream is 10 million pixels of SLR, So Canon's D (New 40d ), nikon's d200/D80/d40x, Sony's a100, and Pentax's k10d are all main models.
3. Price. It's easy to know how much it costs. Most machines with tens of millions of pixels are in the range of 5-7 k, and only the d200 of
the camera's "eyes", generally by a number of lenses, light signal through the period, the lenses will layer layer filter miscellaneous light (infra-red), so, the more lens film, imaging the more real.
From the raw material, the lens can be divided into plastic lenses (Plastic) and glass lenses (Glass), glass lens tra
How to obtain the highest quality of HD Images
I. Exposure problems:
Exposure is the basic problem of video recording. Whether you use traditional films to take photos, make movies, use films to make movies, use digital recorders to make movies, or take digital photos, you must face the issue of exposure. In the past two decades of film work, I have shot about two or 3 million feet of film, which is about eight or 0.9 million meters. I am not sure I can control the exposure. Nowadays, HD cameras
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

compression of the file itself. Like the compression of other data files, it is the optimization of the file data storage mode, using a certain algorithm to represent duplicate data information, the file can be completely restored without affecting the file content. For digital images, the image details will not be lost. Lossy compression changes the image itself, while retaining a large amount of brightness information while saving the image, and merging the color and purity information with t

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.

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)

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

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

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.

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

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
