highlights. Using surround exposure to take multiple photos under different exposure values, later in the image processing software, they are combined to enhance tone and quality. 　　 3. Light When shooting food, the natural light from the window is the simplest and the best. You can put food dishes in the vicinity of the window, so that the food enveloped in the indirect sunlight. If the light coming through the window is direct, try masking it in front of the window with a thin

lower sensitivity. Four, the lens path has the pollution, causes the light not to arrive smoothly. The reason is that the working environment is poor, there is pollution, long time, dirt attached to the light-emitting tube, photosensitive tube, lens and reflector surface, blocking the path of light access to light path. The treatment method is to use cotton ball dip anhydrous ethanol scrub, scrub parts including light-emitting tube, lenses and mirro

to an optical sensing device (micro-imager) for imaging through a set of optical lenses. In this way, when the optical mouse moves, the mobile trajectory will be recorded as a group of high-speed shooting coherent images, the interior of the optical mouse a dedicated image analysis Chip (DSP, that is, digital microprocessor) analysis and processing. By analyzing the location of the feature points on these images, the chip is used to judge the directi

precision and anti-fouling dual revolutionary breakthrough! The illumination of optical system is higher; The traditional optical mouse's light spot shape is relatively sparse, and the maximum illumination is only 1000Lux, while the ghost hidden wave intensity reaches 54400Lux, is 54 times times of the traditional optical engine, from the technical data analysis can be "phantom hidden Ghost Engine" Technology is more technologically superior than the past. To ensure that the mouse tracking mo

Q: I used to take a lot of pictures of high buildings, but these pictures are obviously deformed. The top of the buildings in these photos are converging inward, how can I avoid such a phenomenon in future filming? A: The most straightforward solution is to spend money on a moving axis lens (also known as a perspective correction lens), but these lenses are very expensive. When using a wide-angle focus lens or a wide-angle end of a zoom lens

Beijing time How to apply for live 1, open the Beijing time app, the live number above will have an added option, click, you can launch live 2, input anchor title, you can also switch lenses, all ready to start live, in the process, you can also see how many people are watching your live Beijing time app opens live stream 1, open the Beijing time app, the live number above will have an added option, click, you can launch live!

First, stereo shooting. This method uses the scene photography of multiple lenses, the image of the red and blue visual deviation appears on the screen, must wear the red and blue glasses when viewing. or through multiple lens synthesis technology to make it on the 3D stereo TV on the naked eye to watch stereo video. Advantages: The stereo effect is strong, the visual effect is real. Disadvantage: The production cost is very high, and in the shoo

procedures are reasonable.The program creation process, "Dream Man" is 26 episodes, each episode 22 minutes. The number of lenses is nearly 10,000. summed up in the number, is in the "Dreamer" in the course of the program, I correspond to 10,000 lenses do the work of these:1, the text of the literary script rough shooting2, the lens of the mirror personnel to inspect the scene, proposed specific amendments

This section adds an asterisk, borrow black feather words: "The content of this section is somewhat difficult, if do not understand, can temporarily do not look, wait for later encounter similar problem, come to consult again" 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 circl

correcting the tilt of a building with PS Q: I used to take a lot of pictures of tall buildings, but these pictures are obviously deformed. The top of the buildings in these photos are converging inward, how can I avoid such a phenomenon in future filming? When shooting a building with a wide angle, we notice that the building will be more or less deformed, and this article does not discuss how these variants are produced, but focuses on how to correct these deformations. The following figure

Shift-Axis photography (tilt-shift photography), refers to the use of shift-axis lenses created works, the photos taken is like a miniature model, as if we played the toy world as a child. Moving the axis lens, is used to modify the normal wide-angle lens when taking pictures of the perspective distortion problem; For example, the shooting of buildings, the general lens will let the high-rise tilt to the center of the'm puzzle, and the use of the shif

, fresh photos are often used in rectangular or square composition way. So our SLR or the general default of a single camera 3:2 or 4:3 of the photos will need to do two of the composition--you think a picture of the most essential part of the cut out, and then the color processing processing. The square is trimmed in a fresh style of two times the characteristics of the composition because most of the resolution of our photos is very high, take 6000x4000 as an example,

To enrich the image, photographers put a variety of special films in front of the camera's lens, so that the photographs included the special effects of the lenses added. is called "Color filter". The idea of special lenses extends to the computer image processing technology, then produces "the filter (Filer)" In the PS, also called "The Filter", is one kind of special image effect processing technology. G

tube, lens and reflector surface, blocking the path of light access to light path. The treatment method is to use cotton ball dip anhydrous ethanol scrub, scrub parts including light-emitting tube, lenses and mirrors, photosensitive tube surface, to pay attention to anhydrous ethanol must be pure, otherwise the more clean the more dirty, can also be cleaned with anhydrous ethanol, alignment lenses and refl

course, this is only used after the system, so that the image more sharp, the main body more prominent and then, we also need a lot of skills in shooting, to take the most sharp and clear photos, simply listed as follows: 1 Use tripod, remote shutter and even the mirror to advance, minimize any vibration, if you want to hand the camera, try to increase the shutter speed. 2 with small-aperture, general landscape photography people will be set to F/8–F/11, to help the overall picture clear, or
