About shooting skills! What are the techniques for shooting jade metal and reflective on the surface? For light, background, etc., how to take photos is good!

First, preparation before shooting
■ Background color is more convenient for shaping the contour of the jade
First, put the jade in the appropriate background before considering how to use light. If the jade ware is configured with a light -colored background, the color will be close to each other, which is not conducive to the outstanding contour. When using the tough light to check the detailed decoration, leaving projection in the light color background, which brings interference to the reproduction of the outline of the jade ware. Essence Therefore, most jade wares should be settled with dark backgrounds, such as dark gray, dark brown or dark green. It can set off the outline of the jade, and don't have to worry about the projection in the background.
■ Use macro lens to clearly express patterns
The size of most jade wares. Only by amplifying two or three square centimeters of size several times can we clearly express the pattern pattern and the processing marks of craftsmen, so Macroscopic lenses are generally used when shooting. If you use a small DC, you only need to adjust the camera to the macro function.
■ Use white balance to solve the problem of deflection

It the same as the real thing that you want to shoot your beloved jade. First of all, it is necessary to adjust the white balance of the machine so that the pictures taken are the same as the physical color. Seeing a lot of photos taken by jade friends have a cigarette next to it. This method is good. The color of jade is restored correctly.
. The jade articles are tuned
The jade wares that can be erected on the shooting table will not be said, but some jade wares that are more inconvenient are erected, such as jade cards. When shooting, placement is placed during the shooting. There are some methods to use.
a, the easiest way is to fix the jade on the shooting table. There are many ways to fix the jade. You can use wax or double -sided glue, or you can support the jade in the back. When fixed jade articles, the support is small, because the jade is light transmitted. If the support is too large, it will cover the light and leave projection on the jade articles, which is not conducive to the light transmission and texture of the jade.

B, fix the jade on the sulfate paper with tape, then erected the sulfate paper, and shoot after the cloth. The advantage of this is that the light transmission rate of sulfuric acid paper is very good, that is, the jade can be erected without affecting the light effect of the jade. This method is generally used when mating in the later stage. It should be noted that sulfuric acid paper needs to be fixed, it is best not to have wind, otherwise the jade articles will be easily fallen.

c, for the jade ware that is difficult to stand on the table, you need to complete the shooting. We can put it down on the transparent glass down and shoot. Put the background paper that need to be used under the glass. When the light is light, you must complete the lighting of the jade articles, and you must pay attention to avoid and eliminate the reflection of the glass. Generally, it is completed by adjusting the angle of the light. Otherwise, the light on the jade will also be affected.

. According to the characteristics of the jade
, the jade is placed in an appropriate background and placed it, and starts to consider how to use the light. The shooting of jade articles is mainly to show the pattern or pattern on the jade through the role of light. The same shape should also show the overall shape, color and texture of the jade articles. The principles and needs of different types of jade are different, so we must first observe the external characteristics of the jade articles, and then set the light according to the specific situation.
The nature, projection angle, and light ratio are the key to jade shooting.
■ Half -transparent jade
The surface of the semi -transparent jade articles with a decorative pattern with shampoos or shade -engraved patterns. At this time, you must give up the pursuit of the pursuit Drawing.
The lights at the height of the light will have an impact on the reproduction of the pattern. Once the projection angle is dislocated, the decoration will not be available. In actual operation, we can use the principle of reflection angle of light to the angle of light, so that the direction of the lighting is symmetrical with the camera shooting direction, and when shooting from a certain perspective superior. The figure is to use the principle of light to make the surface decoration of the jade clearly display.

tips
1. To show the temperature of the jade, it is necessary to have a certain understanding of the light quality. The use of softening light of different degrees is the key to shooting the jade. Too hard direct light often produces dazzling bright spots on the surface of the jade surface. In addition to being not conducive to the texture of the jade, this type of light spots will also affect the beauty of the picture.
2, light transmission is an important feature of Baiyu's other manifestation of photography. When expressing this feature, the spotlight or direct sunlight is not lacking in martial arts, but the light level is usually placed in the backlight or side backlight to add color to the picture.
It stereo multi -faceted jade
For the decoration in the three -dimensional multi -faceted utensils, a top light lamp is used as the basic lighting, and then prepares a mirror with different sizes in different shapes. Put it flexibly on the workbench, borrow the light of the top light, and put the reflected light into the decorative pattern at multiple angles, so that some of the lines to produce high light, and enhance the contrast to the purpose of prominent decoration. The glass lenses can achieve some subtle effects that can not be achieved. Just apply a thin layer of medical Vaselin on the mirror surface when the soft shooting effect is needed.

Acci -arc -shaped jade
Is when shooting arc -shaped utensils such as jade walls and jade rings, the focus is also on emphasizing the content of the decoration. In order to prevent the deformation of the utensils, its placement position is usually vertical with the photography, and a single light is used for basic lighting. After the shape of the device and the background effect, it is necessary to use a small spotlight to place it with Xiangyang Yang and Xiangyang. The basically at the same angle of the lens makes the light vertically throw it on the surface of the jade. At this time, it will be observed through the camera view glass. The embarrassing relief will appear vividly. Whether the geometric pattern or the beast face will make people see it at a glance.

. You can shoot jade wares without professional lights
For jade friends who do not want to buy recently, use the lighting lights or natural light to shoot jade at home. It is a good way. Let's introduce how to use these two light sources to shoot separately.

The lighting: Jade wares are generally not large, and small pieces of about 10 cm are mostly. Two lights used as lighting are enough, and the light color is white. Function allocation is used with a lamp with soft light paper for basic lighting for the shape of the device and the background. In addition, a small spotlight is used for the portrayal of its local pattern decoration, so that the surface produces highlights. If a single light plus a reflector, it can also meet the needs of lighting. Therefore, the use of lamps is less, and the light should be soft, but the light of the highlights is indispensable. The sharp light produced by it can paint the finishing touch on the most essential parts of the jade. Do not use the flashing light that comes with the camera, which will make the photo exposure excessively and the shadow of the jade.
Natural light, if there is no light, the easiest way is to use natural light from 8 to 10 to 10 in the morning and from 4 to 5 pm, but avoid direct sunlight and shoot under the shadow. The light ratio of the jade and the dark part should not be too large, so as not to lose the detailed level and the ugly shadow. Use a reflective board or a few pieces of white paper on the side of the jade articles, and at the same time achieve the purpose of eliminating projection.
tips
ordinary film friends must make full use of the current light transmittance and reflective material around the current light and ordinary lighting equipment to change the light quality when using natural light and ordinary lighting equipment. The small size of jade is also convenient for us to provide convenience when applying on -site light. When placing, we can fully adapt to the direction of the existing light. When shooting the difficult screens such as the unblocked and font knowledge on the jade card, the light source that can be controlled by subjective control will become extremely important. Essence
5. Correct exposure
Correct exposure can ensure the texture of the jade and the thickness of the color. It is best to use the central key mode when metering, so that the metering is simple and practical, and there is no need to expose compensation. When shooting, the surround exposure mode also uses the mode of surrounding exposure. After shooting, you can use the curve diagram of the observation photo to determine the accuracy of the exposure.
In short, the overall effect should be taken care of in the shooting, and the other side should not be ignored for the somewhere. It must be comprehensively considered from the whole to the local area to have a complete work.

three major elements of jewelry jade jadeite jewelry shooting. The jewelry and jade jewelry want to take good looks, beautiful and attractive, and there are three key elements.
1, is the background composition
2, color balance (white balance)
3, with light and exposure to phase, clarity.
This three keys are ready to shoot beautiful, excellent, and attractive.
The following three points are explained in detail:
: Background composition
The composition background of jewelry or jewelry such as jade crystal. Different types of jewelry have different characteristics. For different characteristics, ingenious composition of composition Scenery can reflect the beauty of jewelry itself.

It jade shoots, because most jade articles are green, white, cyan and other blue cold colors. When shooting, consider the hue color of the jewelry itself, and use the yellow with a certain color contrast on the background. Warm brown and other colors can better reflect the blue and cold color feeling of jade articles. Jade artifact itself has its cultural connotation, the special nature of the ancient charm, and the material of wood or bamboo as the background, which can not only form contrasts with the cold color of the jade in color, the color of the items is more ice, and it can be well reflected in a good manner. The cultural charm of jade articles.

The jade ware itself is gentle and delicate, and the texture is light. When choosing the background, if the background texture can be rough, it can better set off the texture of the jade. Some people say that some things such as sheepskin paper, bamboo slips, etc. are all good choices, and even the texture of an old mat is easy to use. You can use the various debris around you to try the different feelings shot from different backgrounds.

Is when choosing the background, you should pay attention to the color contrast, which can be too strong, and the color gap between the jade itself should not be too large. The big background, the ideal of wanting to shoot, has a certain difficulty in metering exposure, it is best to avoid it.

The depth of the camera lens is very important to compose composition. It can be cleverly used to better highlight the theme and beautify the effect of the whole.

The shooting composition background of crystal jewelry:
The color of the crystal jewelry itself is colorful and very bright. In my opinion, it is best to reflect the beauty of crystal. In fact, the white background or simple black background. The background of other colors is easy to disturb the color of the whole. It affects the expression of theme, but it is not good.

The white background does not refer to a piece of white paper with pure white. The white background with good texture and fine texture is more beautiful than pure white paper, and at the same time play a rich picture. It does not affect the theme expression and is not too monotonous. My own background is my white real silk vest. White pillow ... and so on. There are also many white -prolatta cloths and so on are good choices.

When choosing a velvet background, remember, try to choose as little black gold velvet as the background, and the photos on the gold velvet will come out a lot of exposure white spots. The appearance is very bad. Only under the conditions of the shed and other are good. Generally, it is best to avoid using it as much as possible.

The gem diamond inlaid jewelry shooting:
The inlaid jewelry of the diamond gemstone, which is small in size, shiny, and the background effect on the background is very good. The contrast is large, the gloss is eye -catching, and it looks more high -end.

of course, the white background is not ruled out, and the composition is rich in setting. Especially in colorful gems inlaid, clever use of the combination of white and some embellishments, combined with the use of depth of field, will take beautiful photos.

The two -color balance (white balance)
The embodiment of color is very important for jewelry and jade photography. Sometimes the color is a little bit distorted. The color balance is relatively simple, and the white balance of each brand camera is different. When buying the camera, everyone should pay attention to choosing the right white balance.
In general, jewelry photography, automatic selection, manually predict white balance, during the day, these white balance methods are better.
If is a color mode for the automatic adjustment of the color balance;

manual prediction white balance is a exposure method of setting the color mode according to the different light conditions of each shooting;

It usually when shooting during the day. The photos taken are bright, warmer, and saturated a little bit.
I I used to choose the automatic white balance mode.

In camera shooting, there are often a little bit of color, and the color is not necessarily 100 % accurate. If you can have a little Photoshop's drawing skills, you can process the colors in the later stage and correct it. More accurate colors.

The premise is as real as possible. It is not recommended for beauty. It deliberately uses later treatment.

three: use light, and expose to the appearance, clarity.
This is the three problems. In order to facilitate the division, the

respectively explained in detail
nPlash with light to reflect the crystal texture.
It people ask me why the same thing, sometimes it ’s so transparent, transparent, and the glass feeling is particularly strong. Sometimes it feels very incompatible. It is the same thing. Why is the gap so big?
is actually the relationship between light and things itself, as well as the relationship between the angle of the camera.
The best light source is the natural light source. Any studio, shooting light sources, is chasing the daylight during the day. Of course, it is not good at all day during the day. It is ideal for two times to shoot.
In noon, the sun is straight above the head, the light angle is hit straight, and it is difficult to shoot ideals.
The better shooting time is from 9.30-11: 00 pm 2.00-4: 30
(Most of the time, the latitude and longitude of the country, the sun is not the same. ) At this time, if the light source is at the outermost, and the shooting object is dozens of degrees, and then the camera, the light comes from behind, transmitted the shooting object, the shot will be very transparent, and the crystals will feel very good. Essence
otherwise, you put the object on the desktop, and the camera lens is taken down vertically.
In someone to take the pendant, bracelets, etc. between the two fingers, and let the light from outside the house, through the items, the camera in the room, in the darkest part, the shooting is so transparent, that is, the light uses the light to use the light to use the light to use the light. The projection relationship with objects.
often cloudy days, or the shooting time cannot be accommodated during the day, you need indoor shooting, indoor photography is more complicated than light. At least there are two -three light sources to be beautiful and real. And the technical difficulty in shooting is much higher, so I won't go into details here.

2. The lower the amount, the more details will be reflected. I set a slightly lower exposure when I shoot, and the later period is brightened.
The person to select the appropriate exposure according to your camera conditions, and find the exposure that suits you as the principle of reflecting the texture of the decoration as the principle as carefully as possible.

3, definition
The definition is important to reflect items, especially the beautiful texture of the jewelry itself. If the clarity is not enough, it will lose a lot of beautiful texture. It is recommended that you try to choose the pixel high and become good cameras. When the size is set, the setting is maximum, the file is large when shooting, and it is reduced to the computer, which is clear. There are also some post -processing methods, which can improve the clarity. You can use it, improve quality, and clearly reflect the beauty of jewelry.

A many people press the shutter, and they are unstable camera, and the tripod is very troublesome. Here I teach you a tips. Find a small box with a large length, width and height gap, the best colorless transparency (I am a cotton swab box bought in the supermarket). The different lengths of the three sides of the box are equal to three different height tripods. It's enough to change the side of the box from another angle. It is very convenient. When pressing the shutter, it will not be false, and the transformation is flexible, which is more useful than a tripod.

The talk about how to shoot good jade articles once, I hope that I can talk about how to shoot good products in the forum and because I only collect the jade, so how to shoot the jade wares to talk about the following points. Experience is willing to have a discussion with friends. One must have a digital camera with more than 5 million pixels. It is recommended that many mid -price models with professional lens models are configured with German Zeiss special lens. The Canon model is also a good choice of two jade shoots, which is not suitable for sunlight direct shooting or adapted to lights or shooting with flash, especially close -range and macro. The main light and auxiliary light ratio of the light source auxiliary equipment will be used 3 to 1 as a 3 to 1 as a better sensor to adjust the reflux device between 2 to 1 to 4 to 1 according to the light sensing of different jade wares. Fourth, I do n’t adapt to the bright bright background shooting, and it ’s not suitable to choose red and yellow orchids as the background. So shooting jade articles must be used for several different background paper black backgrounds. Of course, such as shooting dark jade and jasper and other jade articles should choose light -colored backgrounds such as light gray gray, so gray is also a gray with different universal background. The accurate combination of the fundamental light and shadow of photography skills can achieve a good work. Friends who really need to work hard should remember to use the light of 45 degrees on the light. If the effect can be applied to the side of the backlight and the shooting corner, it will often get amazing effects. The rest is that the rest of the post will not be used too much. Some friends and friends have this requirement. The two are also exchanging Jade and friends

. My 60D basic settings:
. Basic settings in the menu:
1, picture quality: Raw. This format details are more abundant. In the later period, you can adjust the white balance, sharpness, color saturation, brightness, contrast, etc. in the later period, which has a small impact on the film. In the later adjustment software, you can choose a randomly attached DPP software. For how to use this software, see the manual!
2, prompt sound: enable. The reminder of the sound is good.
3, unpack storage card release shutter: prohibited.
4, image confirmation: 2 seconds. Novices can set 5 seconds, masters can be closed.
5, surrounding light volume correction: Close, this should be set according to your own lens, I set it to close. Including many of the following items to be closed, it is mainly required to be fast, because the more adjustment items are turned on, the slower the picture processing speed of the camera, which is not conducive to capture.
6, reduce red eyes: open. The purpose is to forget to open it when you shoot night scenes.
7, flashing light: enable. The shutter synchronization: the front curtain synchronization. Flash exposure compensation: temporarily set up positive and negative zero, and adjust it in a timely manner according to the specific situation of the shooting. E-TTL II metering: Evaluation metering.
8, exposure compensation: I feel that the metering of 60d is slightly deviated. When I normal, I set to -0.3. The time is adjusted in time according to the situation.
9, automatic brightness optimization: disable. The purpose is to improve the speed.
10, light metering mode: Multi -evaluation metering, close -up shooting uses local metering, more fine shooting, backlight and other special shooting points metering and light ratio scene shooting uses the central key average metering. The optical mode needs to choose the best way according to the specific scene of the shooting.
11, custom white balance: You can set it yourself when you encounter a scene that may produce good movies, and the general film will not cost that energy. Leave it for later adjustments.
12, white balance offset/surround: operated, not formal used during filming, very important films are also good. After setting offset and surrounding, set the driver mode to a continuous shoot, press the shutter, press the shutter, press the shutter, press the shutter, press the shutter, press the shutter, and press the shutter. There will be a few different white balances. However, after the shooting, you must remember to clear the setting of the white balance offset/surrounding, otherwise your next continuous shooting will become a variety of.
13, color space: SRGB. The color space is not a one or two sentences. It is meaningless to set up the novice and the middle hand. It is also meaningless to set it to Adode RGB. The masters used for commercial printing naturally know how to set it. It should be noted that in terms of color management, the same color space should be kept in the same color space in terms of color management, otherwise it will be miserable.
14, photo style: neutral. I experienced the "scenery" and "custom" process, and finally chose the neutrality of 0,0,0,0. The purpose is to reduce the speed of camera software processing, the clarity adopts the individual adjustment of batch adjustment and color.
15, dust removal data: cancel.
16, ISO automatic: up to 400. This setting is prepared for the basic shooting area, and I have almost no basic shooting area. The ISO of the creative shooting area can be set at any time according to the actual on -site.
17, protective images, rotation, deleting images, printing instructions, and slideshow playback are not important, how to set it with you.
18, display column image: brightness. Brightness is the most important, intuitive and concise.
19, real -time display function: enable. Time to meter: 30 seconds. Autofocus mode: real -time mode.
20, custom function (C.FN): Just like you like it.
It like this:
1, exposure level increase: 1/3 level.
2, ISO extension: disable.
3, the flash synchronization speed in the aperture priority mode: 1/200 seconds (fixed).
4, long -term exposure noise reduction function: disable. The special, exposure time for more than 5 minutes should be enabled, and the noise reduction effect is obvious.
5, high ISO noise reduction function: standard.
6, highlight color tone priority: disable.
7, automatic focus assist light flash: enable.
8, reflector pre -rising: disable.
9, shutter button/automatic exposure lock button: 0 Automatic focus/automatic exposure lock
10, allocated SET button: 0 ordinary.
11. When the power is turned on, the screen display status: 0 Enable the LCD monitor display.
12, add image verification data: 0 disable.
. Other settings
1, shooting mode: ①AV file (aperture first). It is a shooting mode that the shutter is automatically determined by the camera by the photographer. This is my most commonly used model. It is also recommended that beginners learn this model first. The biggest advantage is that it is convenient to achieve the right depth of field from controlling the aperture and focal length.
②TV files (the shutter is preferred). The shutter is determined by the photographer, and the camera automatically determines the shooting mode of the aperture based on the metering result. Control the shutter by yourself so that you can reach at least the safety shutter. It is better to shoot a sports object. It is also often used to shoot when using the flash. It is much better than using other gears when the curtain is synchronized in 1/200 seconds.
③P file (program mode). The aperture and shutter are automatically determined by the camera according to the results of the metering. It is mostly used for novices to use it without confidence. It will ensure the clearness of the film, but it will lack the creativity of the photographer. When using this mode, you need to pay attention to the choice of light metering. Different light metering methods have a great impact on the results of the film. Generally speaking, evaluation metering is mostly adopted.
④m gear (manual mode). This is the most creative model and the charm of all manual cameras. Photographers can freely set up projects such as aperture, shutter, disable flash, etc., and shoot special films such as high -profile and dark tones. The M gear is also the best mode of night scene shooting. When beginners learn, they can gradually transition from the AV mode to the M mode. But don't think that you do n’t have face to take SLR in your hand without M mode. Many masters do not only use M files. Excellent films are not taken in a full manual mode. The shooting mode is just a means. The final film effect is effective. It is the last word.
⑤A-DEP file (automatic exposure of automatic depth of field). Nine focus points are detected by focusing at the same time and determining depth of field and metering to automatically determine a shooting mode. It feels boring, the depth of the field is still decided by the photographer himself.
2, driver mode: ① Single shot: Needless to say, the most adopted.
② continuous shooting: AIFOCUS (artificial intelligence autofocus) and AISERVO (artificial intelligence servo autofocus) in the autofocus mode are quite effective for sports objects.
③ Selfie/remote control: After pressing the shutter, take a delay for about 10 seconds and shoot/use the remote control to shoot.
④ automatic delay shooting: I set to 2 seconds delay, which is often used for shooting night views.
⑤ Automatic timer. Snacking: After pressing the shutter, about 10 seconds after delay in the shutter, start shooting after about 10 seconds, and the number can be set.
3, autofocus mode: ① Single automatic focus: cooperate with autofocus points Single focusing, nine -point focusing. My most commonly used is this single autofocus and central single -point focusing.
② Artificial intelligence autofocus: Suitable for shooting objects that are fixed first, such as shooting pigeons. When the pigeons do not move, start focusing. After the pigeons move, the focus mode is immediately switched from a single autofocus mode to an artificial intelligence servo. Automatic focus mode, automatic tracking focusing, cooperating with continuous shooting, you will capture the wonderful moment of pigeons take off.
③ artificial intelligence servo autofocus: Suitable for shooting fast moving objects. If you set the focus point to the central single -point focus, after using the single -point focusing focus, once the subject movement is separated from the central focus point, no matter whether it reaches any other eight focus points, it will continue to capture and keep the focus. In fact, the linkage of nine focusing points continues to focus, which is really good for the shooting of sports objects.
4, photo style: neutral. It is 0,0,0,0. The purpose is to maintain the original film and adjust it to the later period. This setting can be set according to different shooting and other shooting. If the film is directly released, the later period is not adjusted, so you should make a custom settings so that the effect of the film will be better.
5, white balance: automatic. Because I am in the raw format, the white balance can be adjusted at will later, just put it automatically. If you do not adjust the later or the picture of the JPG format, you should choose the appropriate white balance according to the situation at the time to set it in time. The white balance should be customized for important films so that the film will not be colored.
6, ISO sensitivity: The principle is that it can be low, but it is not possible. There is still no problem within 800.
7, exposure compensation: I always feel that the metering of 60D is bright, so I often use -0.3 under normal sunlight. This advantage is that the film will not be overexposed. This is very important. Once it is overexposure, it is incurable in the later period, and the increase in exposure is just to raise your hand for the later period. Especially for remote films, there will be no regrets. In addition, the exposure compensation of 60D has reached 5 positive organs, which can be described as very broad. This function is very practical. It is more convenient for the shooting of backlight, sunset and dark films. Many novices do not pay much attention to the use of this function, it is a pity. The M file can also be set up by setting siege exposure and cooperating with continuous shooting to achieve a shutter of three different exposure films for HDR and film use, which improves the tolerance of the film very much.

The choice of light metering method, as follows:
about how to choose the light metering mode:
. Let's understand the differences of several light metering modes:
1) Evaluation metering is the standard light metering mode of the EOS camera, which is suitable for most shooting subjects. After detecting the position, brightness, background, front and rear lighting conditions, and other comprehensive lighting elements in the viewfinder, the camera set the correct exposure for the main subject.
2) Local light metering is very effective for the background due to backlight and other reasons. The metering is more important than the center of the viewfinder, covering a part of the center of the viewfinder.
3) Point metering is used to measure the light to mete a specific part of the shooting subject or scene. The metering is more important than the center of the viewfinder, covering the small area of ​​the center of the viewfinder.
4) The average metering of the central center is more important than the center of the viewfinder, and then to the entire scene.
. Let's take a look at how to choose:
1. Evaluation metering: In most cases, the evaluation metering can get basic accurate exposure values. Therefore, it is suitable for the shooting of most scenes that are more uniform in the picture.
2. Local metering: Generally used for the shooting of backlight films.
3, point testing: If you are sure that the surrounding part is not necessary, the local metering and point optical measurement can get more accurate exposure values. This will maintain the correct exposure of the main body, and the background will be too bright or too dark. Generally, macro and close -up shooting will be used.
4. Central key average metering: If you are sure that the surrounding part is only considered, you can choose the central key average light metering. In this way, the subject is not particularly ideal, but the surroundings and backgrounds will not be too bright or too dark, and they will take into account both. Suitable for morning light, sunset, sunset, etc.
60D's 64 -bit light metering system is the same configuration as 7D, which is quite good. However, the light metering system is dead, and people are alive. When choosing the light metering mode, pay attention. Once the scene or the effect you want is not so in line with the standard situation of the metering mode, you need to interfere with the optical results. At this time, exposure compensation is the best choice, and the wide domain of positive and negative 5th gear will make you very satisfactory. In addition, in the actual operation process, the selection of the latter metering point in the latter three modes is very large (for example, when the light metering area reaches 4%), this must be taken when shooting Notice.
Also. In the evaluation of the metering mode, half press the shutter will lock the measurement results and exposure combination. The latter three methods are not. You need to press the exposure lock button to be locked. The composition of the latter three types of light metering mode must be locked first, and then move the composition.

Afghan jade and so on! The quality of jade is identified and identified the quality of jade. There are six standards, namely, "the better the color and the polishing, and the stronger the surface reflectivity, which not only increases the beauty of jade, but also improves the quality of jade.
