4. Manual shooting skills of SLR camera
1. Take close-up pictures of small still objects, such as flowers, birds and insects:
use AV file, the aperture should be f5.6 or below, the focal length should be more than 50, and try to shoot within 1m to make the background virtual
if the light is good, ISO 100, if the light is bad, ISO should be within 400<

2. Shooting people:
basically use a large aperture (within f5.6) and a focal length of more than 50 mm. The shooting distance depends on the whole body, half body and big head, which makes the background virtual. Use AV file
good light, iso100, bad light, iso400
people in motion use tracking to reflect the sense of motion (see the shooting of moving objects below for details)<

3. Shooting:
AV file, use the appropriate aperture, above F8, the focal length is arbitrary, but generally the wide-angle end has distortion, use it as appropriate<

4. Shooting night scene:
upper tripod, AV gear, custom white balance or incandescent lamp, aperture above F8, small aperture can make the light proce starlight effect, use the reflector pre rising function to rece the vibration caused by the reflector lifting after pressing the shutter; And cover the viewfinder with the square cover on the strap to prevent stray light from entering from the back and affecting the image quality; ISO 200, as far as possible to make the exposure time longer, so that some people who have no intention to walk away from the screen disappear, leaving no traces, clean the scene
for example, when taking a square with people coming and going, you can use a very small aperture of about F20 and iso100. In this way, the exposure time will be very long, and the moving figures will not stay in the photos! The square will be clean<

5. Shooting fireworks:
using shutter line and B shutter, you can shoot multiple fireworks overlapping effect<

6. Shooting things:
when the light is good: AV, the aperture size should be handled according to the circumstances; Large depth of field can be obtained by using aperture above F8, and shallow depth of field can be obtained by using small aperture
if you want to have a very dynamic effect, you can use the TV gear, the shutter is about 1 / 30, when you focus and press the shutter, the lens will follow the object at an appropriate speed, which will proce a very dynamic effect
poor lighting: we can only handle it according to our own discretion, plus use the follow-up camera<

7. Shooting running water or fountain:
using TV and about 1 / 50 shutter speed, you can shoot Satin effect. If you use too fast shutter speed, the fountain will shoot discontinuous water drops<

8. Taking photos at night:
use tripod to adjust white balance, and automatically or custom white balance; iso100-400 AV gear, aperture about F8, use slow synchronous flash, rear curtain flash mode; At this time, the flash will flash twice, press the shutter to flash once, and flash again before the end of exposure, so don't leave before flashing twice
in this way, the characters can be clear and the background neon is beautiful, so that the background will not be too dark e to insufficient exposure< No matter what you shoot, don't shoot with the maximum aperture unless you want to keep a safe shutter
2. Please use the aperture of F8 ~ F11 as much as possible when shooting scenery
3. The maximum aperture can be reced by 1-2 levels when taking close-up of people and still life
4. The safety shutter should be controlled above the reciprocal of the focal length as far as possible. The wide-angle shutter should also be more secure at more than 1 / 30 second. If the shutter is insufficient, please increase the aperture or ISO<

metering method:
1. Don't measure the light to the sky or the darkest place. Go to the middle value
2. According to your subject matter, make good use of the metering mode (balance metering, point metering, central key metering...)
3. If the light measurement is not accurate, please use AE lock to expose and lock the gray things around you before shooting
4. Try not to measure the light on white or black objects, otherwise remember to rece eV for black and increase eV for white<

EV is exposure compensation.
exposure compensation is also an exposure control method, which is commonly used in ± If the ambient light source is dim, the exposure value (such as + 1eV, + 2eV) can be increased to highlight the clarity of the picture
most of the small digital cameras adjust the exposure compensation through the menu
in the process of shooting, if you press half of the shutter, the LCD will display pictures similar to the final effect picture, focusing and exposure will start. The exposure at this time is exactly the exposure of the final picture. If the picture is obviously bright or dark, it means that the automatic metering accuracy of the camera has a large deviation, and the exposure compensation should be enforced, but sometimes the brightness displayed ring shooting is different from the actual shooting result. Digital camera can browse the picture immediately after shooting, at this time, you can more accurately see the brightness of the picture, there will be no difference. If the shooting result is obviously bright or dark, it is necessary to re shoot and force the exposure compensation
the shooting environment is dim, and the brightness needs to be increased. When the flash cannot work, the exposure can be compensated and the exposure can be increased appropriately. For exposure compensation, if the photo is too dark, increase the EV value. Every 1.0 increase in EV value is equivalent to doubling the amount of light intake. If the photo is too bright, decrease the EV value. Every 1.0 decrease in EV value is equivalent to doubling the amount of light intake. The compensation interval can be adjusted in 1 / 2 (0.5) or 1 / 3 (0.3) units according to different cameras
when the white object to be photographed looks gray or not white enough in the photo, it is necessary to increase the exposure. In short, "the whiter the object is, the more white the object is." this seems to run counter to the basic principles and habits of exposure. In fact, it is not. This is because the main body of the camera is often the center of the light measurement, and the White main body will make the camera mistakenly think that the environment is very bright, As a result, the exposure is insufficient, which is also a common problem for most beginners
because the shutter time or aperture size of the camera is limited, it is not always able to reach the 2eV adjustment range, so the exposure compensation is not omnipotent, and it may still be underexposed in too dark environment. At this time, it is necessary to consider cooperating with the flash or increasing the ISO sensitivity of the camera to improve the brightness of the picture
generally speaking, the smaller the brightness contrast of the scene, the more accurate the exposure, otherwise, the larger the deviation. The grade of the camera is high and low. If the grade is high, the metering is more accurate, and if the grade is low, the deviation will be increased. If it is a traditional camera, the tolerance of film is relatively large, and the exposure deviation will not have a big problem within a certain range, but the CCD tolerance of digital camera is relatively small, and slight exposure deviation may affect the overall effect
in a word, the adjustment of exposure compensation is determined by experience and sensitivity to color. Users must compare the image quality, clarity, restoration degree and noise size under different exposure compensation to get the best picture

note:
the aperture in Canon's manual refers to the F value. The larger the aperture, the greater the depth of field
generally speaking, aperture refers to aperture, which is inversely proportional to F. the larger the aperture, the smaller the depth of field
AV -- aperture priority auto exposure
TV -- shutter priority auto exposure
AE auto exposure
AF auto focus
AF-S -- single auto focus, the same as saf. The opposite is continuous autofocus
MAF - monitor AF, which can shorten the focusing time. The camera will adjust the focus before half pressing the shutter button, so that you can compose with the adjusted focus. When the shutter button is half pressed and AF locking is completed, the focus will be locked
ev - exposure value, which is usually used in exposure compensation
ISO sensitivity. Each difference of sensitivity is equivalent to the corresponding exposure value of aperture or shutter

5. First of all, we can't find too much information about the virtual currency golden seed on the Internet. Second, the most basic information of this currency is not open and transparent. This kind of currency investment is absolutely risky. Bitcoin, Ruitai, Laite and Weimeng are different. There are media reports and the information is open and transparent.

6. Beta is the trend of financial development. Visionary people are investing in it one after another,
10 coins a day,
6.5 coins can be traded,
3.5 coins are automatically re invested,
a gold coin is equal to 1 RMB
when the reinvestment reaches 1000, the system will automatically add another mint, and then there will be two mints to help you make money, two of which will pay dividends of 20 coins a day,
and so on, three years later 128000
it's just a static income from the market. If we do marketing, we will have a lot of money!!! If you only invest a single 1000, it will be a mint at the beginning and more and more at the later stage. That's how circular compound interest comes. This is how money can help you make money. Compound interest is powerful! Do dynamic development, a few people will make money faster, there are all kinds of bonus to take, not just every day bonus money<
static:
a mint of 1000 yuan can proce 10 coins a day,
65% of them, that is, 6.5 coins, accumulate to 100, which can be sold and cashed into RMB,
the other 35% of them, that is, 3.5 gold seeds, accumulate to 1000, and automatically buy a new mint, which can proce 10 more gold coins a day
for example,
each Mint has a total of 2000 coins, of which 1300 coins can be cashed, 700 were converted into gold seeds
you can choose to convert one to 100 gold coins initially generated into cash to recover the cost first
of course, there are people who do not cash at the beginning, but adopt the method of re investment, that is, when there are 1000 gold coins in 75 days, the gold coins will be turned into gold seeds by manual operation. At this time, a new minting machine will be added automatically, and the proction capacity will double to 20 yuan per day, 30 yuan after 38 days, 40 yuan after 25 days, 50 yuan after 19 days, 60 yuan after 15 days, After 13 days, 70 yuan, after 11 days, 80 yuan, after 10 days, 90 yuan, after 9 days, 100 yuan, after 8 days, 110 yuan, that is to say, after 270 days, 190 gold coins can be proced every day, and after one year, 650 gold coins can be proced every day. Of course, it's actually faster because there are other bonuses

Today's bitcoin has been in a rising state. Experts suggest that we should not start with it. After all, the rising process of bitcoin has been in a constant frenzy, and many people are very unsatisfactory in the process of purchasing. This trading market will definitely have a callback in the future, So it is suggested that the best thing now is not to buy admission

First, this is a kind of crazy speculation

the reason why there is such a big rise is entirely because the recent speculation is very crazy. The admission of funds has a huge impact on the speculation of bitcoin. Basically, the price rise of any kind of assets has a great relationship with the large amount of funds{ RRRRR}

in fact, I have been paying close attention to the change of the price of bitcoin recently. In recent years, the price of bitcoin has been rising fiercely, and it has a great influence on the society. After all, equity assets can no longer be compared with the rate of return of bitcoin. The rate of return of bitcoin has exceeded tens of thousands of times, Equity assets can only rise by about 20% or 30% in a year, which is not comparable
