CMOS is integrated in the semiconductor material called metal oxide, the working principle is not the essential difference, it is the photoelectric conversion using the photosensitive diode (photodiode), The principle of this conversion is similar to that of solar cells, the stronger the light, the stronger the electricity, and the weaker the light and the weaker the electricity. According to this principle, the image is converted into digital data, and the main difference is that the digital d

should be based on standing upright. The so-called "correction" also has two meanings: one is the positive direction in the trunk limbs and head position, that is, the body is not balanced; the other is the body in the case of skew, maintain a relatively balance, such as the up and down actions during the start of the step. The so-called "relaxation" means that, under the support of the legs, all parts of the whole body are naturally Matsushita, and the data is naturally relaxed. At the beginni

exposure value, so in the night scene photography is also very convenient. If the first time to challenge night photography, we recommend that the first attempt to use the model. 2, can set any ISO sensitivity to prevent hand jitter What you need to be aware of when holding a camera is the hand jitter caused by a slow shutter. While using the lens of the hand jitter compensation mechanism (IS), it is necessary to ensure a high

The magnet on the earphone horn sticks to the Tiemo or other sundries, this sundries presses between the magnet and the horn diaphragm, causes the diaphragm to contact with the magnet, emits the murmur, this question only has changed the horn. 3., the horn

. The acquisition end control is mainly for the software acquisition, the acquisition command is automatically cleared after the end of the single frame acquisition, and the collection command to be issued by the computer to clear the command is collected continuously. Exposure (shutter) The shutter is the control of the exposure time. The traditional camera is the exposure control

Beginners know that to take a clear photo, they generally need to: Use a high-speed shutter to reduce the aperture from the largest aperture to four levels; there must be a lot of light on the subject, the object to be taken should remain static, the tripod should be placed stable, and the action should be light when the shutter is pressed. However, even if you pay attention to this, many experienced photog

To the photography enthusiasts to the detailed analysis to share the Canon 1100D camera to take out the brilliant night photos of the skills.

Recently began to study photography, summed up the previous learning, both for sharing, but also to record. 1. Exposure, determine the quality of a piece of the most critical objective factors Means of controlling exposure: aperture , shutter speed . If the exposure is analogous to the desired bucket of water, the aperture is the faucet size and the shutter speed is the time the tap is opened. The same amou

area, the 120 SLR series, represented by hasoro polo, seems to be more "slim" than the 135 series! Today's APS and 4/3 digital SLR are even more bloated!Let's look at the vibration of the SLR camera: What happened after we pressed the shutter? A series of mechanical actions taken by an electronic automatic single-camera (including digital slrs) as a photo are complex: including the zoom, focus of the motor drive, the overhead value provided by the pr

D80 Experience 1 1. Focus Although the D80 has 11 focal points, only the center focus is the cross focus. In other words, this is the most accurate point focus, so I have been locking the center focus for a long time. After getting used to it, the chart is also very convenient. First, align with the subject, half-press the shutter, and then move the camera in parallel. The focus is basically OK. 2. Metering D80 is a bit of test and easy to use

cameras have autofocus, they can still use manual focus. A lot of people have the misconception that autofocus is more accurate than manual focus, but it is not so, the advantage of autofocus is fast and fast, but it is manual focus. This is most obvious in macro and weak light photography, because the physical principle of camera autofocus (ranging focus, contrast method, phase focus), it is prone to deviation in weak light, macro photography is more precise focus, the camera itself difficult

Digital cameras, as an outstanding embodiment of digital technology, are becoming a new favorite of consumer electronic products with their superior quality of use. They have gradually begun to enter ordinary homes, however, it is expensive, so we should be cautious when choosing a digital camera. After all, it is a "luxury" among computer peripherals ", therefore, correct and safe use of digital cameras has become a topic of great interest to all of you. In order to help users who have just beg

1. Use a tripod whenever possible In many cases, the reason for blurred and unclear photo images is that the photographer produces a "Hand vibration" When pressing the shutter or a "machine vibration" when the camera reflector is raised. If a tripod is used, no matter how slow the shutter speed is set, or even prolonged exposure, it can prevent Image Blurring due to image jitter. However, when using a trip

The 16 rule of sunshine. This basic law applies to scenarios where bright and even lighting is taken during the day, that is, when the aperture is F16 and the shutter speed is the reciprocal of the sensitivity index, such as the aperture F16 and the sensitivity is Iso100, shutter speed can be set to 1/100 seconds. On this basis, the aperture can be reduced to f22 if shooting on the beach, and the aperture c

15 days in a row: transformation-from the side axis to the SLR Author of Legend of SLR cameras: Mu Introduction: In the early 1950 s, there were two mainstream cameras: The side axis and the double reverse. However, there is also a type of camera that has developed rapidly since this time. This is a single-lens reflective camera, or SLR for short. Xuguangxue seized this opportunity and won the top prize in the SLR field ...... In the early 1950 s, there were two mainstream types of cam

color ratio is to mark the blacklist) after a certain color light is generated, the Gini coefficient plus 273 is the color quality of the color light. For example, when the amount of light used by the shadow is 3200 kb, It is the light that occurs when the standard black body is added to the first 2927 degrees. Shutter:Shutter, as its name implies ........ I'm not talking about it anymore.Shutter usually refers to the exposure time, and sometimes 1/125 seconds
