the text "bulls"). Scroll down to the lens correction panel. There are two options at the top of the panel: profile (it automatically corrects the problem) and manual (we correct the problem ourselves). Let's start with an automated approach, so click the profile and select the Enable profile correction check box. After you complete the operation, the image is corrected (see the image correction effect in the illustration). To create such a small miracle is because it reads the EXI

yuan + 15100 yuan. Advantages: high sharpness, red circle quality workmanship, the recent focus distance shortened. Disadvantage: Lens combination of heavy weight, high price. Well, the above information is a small series of photography enthusiasts brought to the detailed Canon 50D camera with the lens recommended to share all the content, you see the photography enthusiasts here, small series believe that you now that is very clear lens match it, I hope that the small series of the above to

Have you ever had a large, purple-edged picture of your lens? In fact, you only need to use the PS of Adobe Camera Raw in the lens correction function, a few steps to improve these problems, so that "dog head not dog." Common wide-angle zoom lens to take photos, the edge of the screen should be straight lines because of distortion and bending, white frame with purple edge, and because of the careless filming, the picture has a little skew. These are all very common problems. Standa

. Third, shooting techniques (i) About lenses Turn-back lenses are generally manual lenses, 500-terminal telephoto focus is particularly accurate, it is recommended to use the camera's real-time screen manual focusing. (ii) multiple exposures to cameras Take the Canon 5D3 I used for example, first turn on the camera's multiple exposure, multiple

To the photography enthusiasts to detailed analysis to share the Canon 6D camera lens can replace the problem. Analytical sharing: Canon 6D replaceable lenses. Okay, the above information is small make up to you photography enthusiasts brought to the detailed Canon 6D camera lens can replace the problem of all the content to share, you see the photography enthusiasts here, small series believe that you now that is very clear this cam

The focal point of the lens is the highlight, which includes the high light of the edge, the high light and reflective region of the light part. Edge highlights are done directly with layer styles, and other highlights need to be done manually.

camera T1 and incorporated into a smaller and cheaper fuselage, Fuji X-T10 allows you to throw away your smartphone and card machine without hesitation. X-T10 retains retro-style buttons and turntable designs, as well as a handy switch that makes it easy to get started with Fuji users. Best entry level without anti-camera: Panasonic GF7 Panasonic has made it an art to develop small, high-performance, non-GF7 cameras, and this is no exception. Its flexible performance, rapid autofocus system,

After measuring the MTF value curve of each lens, the Hassu lab developed a calculation method for the average value of the MTF. First, the preset focal length is used to calculate the MTF value of the lens F4, multiply by the focusing coefficient of 0.4 and 0.6 respectively to obtain the MTF value of a first-line frequency, and then multiply the average value of the 10-line/millimeter value by the focusing coefficient of 0.57, the average value of the 20-wire pair/millimeter is multiplied by th

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

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

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

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. 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)
