Adjusting the camera parameters of mobile phone

First, the sensitivity
iso50~100 for low sensitivity.
In this section you can get a very smooth, delicate photo. As long as the conditions permit, as long as the photo can be made clear, try to use low-sensitivity, for example, as long as the depth of field can be guaranteed, rather open a large aperture, do not increase the sensitivity of a block.

iso200~800 belongs to medium sensitivity.
In this section, you need to seriously consider what this photo to do, to what extent, if you can accept noise, the medium-speed setting reduces the difficulty of the handheld camera shooting, improve the low illumination conditions of the shooting of the safety factor, so that the success rate increases.

ISO1600~6400 is high sensitivity.
In this section of the noise is obvious, the use of such settings, the importance of the subject matter of the shooting, often more than the quality of the image, after all, sometimes shooting conditions are too poor, to take a picture of a slightly inferior quality, it is better than to capture the image at all.
Personal advice: Near Pat Si Cho low will be better, large scene (scenery) can be adjusted a little bit, but more noise.

Second, white balance
Automatic white balance
Automatic white balance is usually the default setting for a digital camera, and the camera has a complex rectangular chart that determines the white balance reference point in the picture to achieve white balance adjustment. The accuracy of this automatic white balance is very high, but in light shooting, the effect is poor, and in cloudy weather, many automatic white balance system effect is very poor, it may lead to blue.

Tungsten Light white balance
Tungsten Light white balance is also called "incandescent" or "indoor Light". Settings are typically used in environments where the bulb is illuminated (e.g. at home) when the camera's white balance system knows that it will shoot in this environment without a flash, it will start to determine the position of the white balance and use this setting when photographing indoors without using a flash.

Fluorescent white balance
Suitable for white balance regulation under fluorescent lamps, because there are many types of fluorescence, such as cold white and warm white, so some cameras are more than a fluorescent white balance adjustment. Different fluorescent lamps are used in various places, so the "fluorescence" setting is not the same, and photographers must determine what kind of "fluorescence" the illumination is, making the camera perform the best white balance setting. In all settings, the "fluorescence" setting is the most difficult to determine, for example, some offices and schools using a variety of fluorescent types of combinations, where the "fluorescence" setting is very difficult to deal with, the best way is to "try to shoot".

Micro Photographic white balance
Under the microscope, when the light source of different color temperature is illuminated on the sample, the CCD will show a different color. This is because in different light, because of the CCD color signal output imbalance, resulting in CCD color reduction distortion. As the default setting for microscopic cameras, the automatic white balance determines the white balance by using a rectangular graph with a complex structure to determine the white balance reference point in the screen. However, as a special case, the use of manual white balance, regional white balance method to prevent color, the main method is to move the microscope objective lens to the area other than the specimen of the slides.

Indoor white balance
Indoor white balance or cloudy, cloudy white balance, suitable for the dim light to adjust the primary color state. Not all digital cameras have this white balance setting, in general, the white balance system is optimally located outdoors, without these settings. However, some manufacturers have added these special white balance settings to the camera, and the use of these white balances varies depending on the camera.

Manual adjustment
This white balance has different names in various places, and they describe the white balance setting in some general lighting situations. In general, the user needs to give the camera a reference point for the white balance, which is the "white" object in the screen as the white dot. But the question is what is "white", for example, different white paper will have a different whiteness, some white may be slightly yellow some white, and some white may be slightly whiter, and the light will affect our "white" color sense, then how to determine the "real white"? One way to solve this problem is to carry a standard white paper with you and compare it with the subject when you take it. The effect of this method is very good, then in the indoor shooting difficult to determine such a setting, it is advisable to set the white balance according to the "reference" white paper. In the absence of white paper, let the camera to the eyeball is considered to be a white object to adjust.

Three, the focus mode
Auto Focus:
To achieve autofocus in a way similar to visual ranging, the camera emits an infra-red (or other Ray), determines the distance of the subject based on the reflection of the body, and adjusts the lens combination according to the measured results to achieve autofocus. This autofocus method-direct, fast, easy to implement, and low cost-can sometimes be wrong (autofocus is not possible with other things like glass between the camera and the subject, or in the case of insufficient light), and the accuracy is poor.

Macro Talk about it: The simple said, the details, the distinct subject, suitable for people, objects, the scene of a small area of the side, so that the theme of the scenes of the blurred treatment to compare the subject. Not suitable for large scenes (fori phone) of course, good camera effect is also good.
"Normal and infinity" understand autofocus and macro, I think you should be able to understand.

Four, reduce flicker
Everyone can be understood as the screen refresh frequency, the computer's people know that the display sometimes appears to be particularly large screen jitter, so that look uncomfortable, adjust the frequency will directly affect the display effect, generally in (60-120) Hz, different brands have different display effect, millet mobile phone we to it to understand, When the camera shot when the refresh rate, of course, 50 and 60 ratio, 60 will be better, automatic words will adjust their frequency.

Five, metering mode
Average metering
The central average light is one of the most metering modes, and almost all camera manufacturers use the central average metering as the camera's default metering mode. Central average metering is mainly due to the general photographer is accustomed to the subject of the film is the need to accurately expose things in the middle of the viewfinder, so this part of the shooting content is the most important. Therefore, the sensory components responsible for metering will be the overall value of the camera to separate the light, the central part of the metering data to occupy the majority of the proportion, and the center of the screen outside of the metering data as a small proportion of the metering of the auxiliary role. After the camera's processor to the two-cell value weighted average after the ratio, to get the camera metering data taken. For example, the Nikon camera uses the center-weighted average metering, the central part of the Nikon camera metering occupies 75% of the overall metering ratio (this ratio varies by brand), other non-central part of the gradual extension to the edge of the metering data accounted for 25% of the proportion. Central metering is a very practical and widely used metering mode in most shooting situations, but if the subject you need to shoot is not in the center of the screen or in the backlight condition, the central weighted metering is not applicable.
Central metering is a traditional metering method, most of the camera's metering algorithm is attached to the center of the screen about 2/3 of the position, the surrounding is also given some degree of consideration. For photographers who are accustomed to using center-weighted metering, this way of metering is easier to control than using a multi-zone evaluative metering method.
For shooting purposes: personal travel photos, special scenery photos and so on.

Center Weight Metering
The central part metering and the central average light are two different metering methods, the central average light is the central region as the main other area as an auxiliary metering method, while the central part of metering is only one area of the center of the screen for metering, the metering range is about 3% to 12% for metering. The central part of the metering mode is suitable for some light more complex scenes, the need to get more accurate exposure, the use of central partial metering can be the subject of accurate exposure of the photo. The central partial metering can be used for a number of special harsh shooting environments, which ensures that the camera processor calculates the amount of exposure needed for the main object part of the screen. This pattern is most appropriate in scenes such as stage, performance, backlight, but this pattern is now gradually less present in the camera due to the rise of the segmented metering (matrix metering) pattern. Canon, which insists on the use of a central partial metering (partial metering), has designed 9% area-wide partial metering in the newly launched EOS 30V film camera and the EOS 20D DSLR camera. This allows a camera with no spot metering to reduce the effect of light on the subject when photographing images in complex light conditions.
The partial metering method is a partial metering of the screen. When the subject and background have a strong contrast, and the proportion of the picture taken by the subject is not large, the use of this method of metering is most appropriate; In this case, the local metering is more accurate than the 12th type of metering method, and is not as small as the spot metering method because the light metering point is too narrow need a certain metering experience is not easy to
For shooting purposes: accurate metering is required under certain conditions, and when the metering range is larger than spot metering.

Midpoint metering
Central average metering (center-weighted average metering) although it can fully represent the entire picture of the light response, but there are many shortcomings, such as the need for accurate small-scale object exposure accuracy, central average metering (central average metering) is not so good, Even the central portion of the metering (partial metering) sometimes has a somewhat larger range. In order to overcome these shortcomings, some manufacturers developed this spot metering mode to avoid light in complex conditions or backlight condition of the influence of ambient light on the main body metering, the range of spot metering is a minimum area in the center of the viewing window as the exposure datum point, Most point-of-measurement cameras have a metering area of 1% to 3%, and the camera is based on the light measured in this narrower area. This is a fairly accurate metering method, but for the novice, but not so well mastered, how to distinguish a metering point, turned into a need to learn skills, the wrong spot to shoot out of the screen is not exposed is due to exposure, resulting in serious exposures error. Due to the technique of spot metering, it can also be used in the increasingly popular digital camera macro shooting when the big shine, so that the macro part of the exposure more accurate. Therefore, the favorite macro photographer must try their best to learn the metering method, the initial can be selected in the middle of the screen as a spot light reference point. Spot metering is also a good weapon for portrait shooting, which accurately exposes the character's parts (such as the face or even the eyes).
Spot metering is only a small area of accurate metering, regional location of light and shade on the metering has no effect, so the metering accuracy is high, its use is mainly in the distance to a specific small area metering. Mastering this metering method requires the photographer to have a certain understanding of the point measurement characteristics of the camera used, to be able to select a light spot with a reflectivity of around 18%, or to make exposure compensation with experience for metering points above or below 18% reflectivity. The point measurement method is mainly used by professional photographers or people who know a lot about photographic technology. Improper use of the point measurement method will cause chaos.
Suitable for shooting purposes: stage photography, personal art photo, news feature photos and so on.
