The camera takes pictures
The following are a few things to pay attention to when taking pictures with a camera: * * 1. Aperture of the lens ** 1. * * Aperture selection and image quality ** - Different lenses had different maximum apertures. For some low-quality lenses, such as 50mm f1.8, the maximum aperture may not be suitable. The image quality would be much better if the aperture was set at two levels. For high-quality lenses, such as 70 - 200mm f2.8 and 50mm f1.4 (new model), the maximum aperture could be used, but when the maximum aperture was used, the chances of the image flipping would increase. - Shooting with the largest aperture was prone to blurring the picture. First, because the depth of field was shallow with the large aperture, the camera's movement would cause the focus to deviate from the original focus point when focusing first and then composing the composition. Second, some lenses (such as the Sima lens) might run out of focus at the largest aperture, but after two apertures, they might not run out of focus. 2. * * Aperture and depth of field effect ** - A large aperture would produce a shallow depth of field effect. If you wanted to highlight the main body and blur the background, you could choose a larger aperture, but you had to pay attention to the risks mentioned above. A small aperture had a large depth of field, and the front and back scenes in the picture would be clearer. It was suitable for shooting scenes that required overall clarity, such as scenery. * * 2. Shutter Speed ** 1. * * Safety Shutter Calculation ** - Normally, the safety shutter was calculated by the inverse of the focal length (1/focal length). For example, if a 200mm lens was used, the safety shutter would be 1/200. However, it was generally believed that as long as it could guarantee 1/250 seconds, there was basically no need to be afraid of using any lens, and the basic safety shutter was 1/50. - It was best for novices to keep the shutter time at 1/300 seconds to reduce the blurring of the picture. Old drivers might use the safety shutter within 1/10 second under extreme conditions such as poor lighting conditions, but in this case, every shot had to be zoomed in for inspection because the overturning rate was very high. * * 3. Focus related ** 1. * * autofocus problem and solution ** - Although the autofocus mode of the camera was very strong, there were still cases of overfocusing. For example, under the backlighting, too much light would disturb the autofocus system, and the lens might keep pulling the bellows, making it difficult to focus. Even if the camera was barely focused, the picture might not be clear. The solution was to focus on the location of the subject (such as a jumping person), press the shutter halfway, and then press the shutter when the subject reached the appropriate position. - When the lens 'closest focus distance was exceeded, the autofocus system would fail, and the photo taken by pressing the shutter forcefully would be blurred. When shooting flowers or macro scenes, it is recommended to use manual focus to get clearer photos. * * 4. Different camera equipment features (some equipment can be used for both video and photo)** 1. * * Fuji XT5 ** - The advantage was that there were many filter, the film had a texture, and the appearance was high. The 18 - 55 was enough for beginner players. The disadvantage was that although the screen could be folded, it could not be folded into selfie mode. It was difficult to focus and easy to lose focus, which was not suitable for novices. 2. Canon G73 - The advantage was that it was small and light, suitable for recording vlogs or taking photos. The operation mode was simple, and novices could easily master it. The disadvantage was that its endurance was relatively poor. 3. * * Canon A550 (CCD-camera)** - The advantage was that as long as the flash was turned on, it would look good no matter how you shot it. The film had a certain style. The disadvantage was that after shooting with the flash, the reaction time was very slow in an overly cold or overheated environment. It required five seconds to wait, and the battery life was short, usually only one to two hours. 4. * * Fuji F40 (CCD-camera)** - The advantage was that it was smaller and lighter than the Canon A550, and it had a higher appearance value. The photos it took came with a soft filter with warm colors, giving it a sense of atmosphere. The disadvantages were similar to the Canon A550, including slow response and short battery life. 5. * * Film machine (such as the street sweeper film machine of the same model)** - The advantage was that film lovers could experience the feeling of film shooting, and the price was cheap (such as 100 yuan). The disadvantage was that it was difficult and costly. 6. * * Single use film camera ** - The advantage was that it was cheap (about 100 yuan) and could experience film shooting. The disadvantage was that the number of shots was limited. It would be used up after 20 clicks, and there was no chance to redo it. 7. * * Fuji Mini 7C (Polaroid)** - The advantage was that it was suitable for giving gifts, and there was a tutorial to take good photos. The disadvantage was that it was not suitable for many people to use. It was easy to expose it unevenly, and there would be a situation where all the people behind it were little black people. 8. * * LOMO Polaroid ** - The advantage was that the lens could be replaced. For example, the macro or fisheye lens could take more creative photos, and the appearance was good (such as the pink, blue and green color matching). 9. * * Phone (such as XSMax)** - The advantage was that it was convenient. It had a self-sharpening effect and no lens distortion. It could take high-definition photos with texture and atmosphere. The disadvantage was that when the lighting was not good, the recording effect would be low-resolution. Read more exciting novels for free
Why did Yongzheng's mother hate Yongzheng?
Yongzheng's biological mother, Wu Ya, was estranged from Yongzheng, but it might not be accurate to say that Wu Ya "hated" Yongzheng. Wu Ya was born in a humble family. When she gave birth to Yongzheng, her status was not as high as a concubine. According to the regulations of the Qing Dynasty, she could not raise her son personally. Yongzheng was raised by Tong Jia. This made Yongzheng's feelings for his adoptive mother, Tong Jiashi, deep, and his feelings for his biological mother, Wu Yashi, more vague. After Emperor Yongzheng ascended the throne, he wanted to confer the title of Empress Dowager on the Wuya family, but the Wuya family was unwilling to do so. This reflected the disharmony in their relationship, but there were many factors in this, not just pure "hatred". From Wu Ya's point of view, it was possible that she had not been close to Yongzheng for a long time, so it was difficult to establish a deep mother-son relationship. In addition, the complicated political environment in the palace, the power struggle and other factors had caused their relationship to be alienated.

How does a methyls become a carbolic acid?
There were several reactions for the conversion of a methyls to a carbolic acid: 1. Under certain conditions: <anno data-annotation-id ="0000008 - 4110 - 4000-a110-a160-a11111111000">(CH3-+ O2 → COH)</anno>, this reaction usually requires a high temperature and high pressure environment, as well as an acidic catalyst such as sulfuric acid. The first step is to activate the methyls, and then they will undergo an oxidization reaction with oxygen to form the Carboxyls. 2. \(5RCH_3 +6MnO_4^- +18H^+ ==5RCOOH +6Mn^{2+} +14H_2O\)。 3. \(RCH_3 +Cr_2O_7^{2 - }+8H^+ ==RCOOH +2Cr^{3+} +5H_2O\)。 4. First, it was substituted with Cl2 to form-CH2Cl2, then it was substituted with water to form-CH20H. Then, it was successively oxided twice with copper as a catalyst. The first time it was oxided to form-CH, and the second time it was oxided to form-COH. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
A novel about being caught off guard
The following are some of the novel situations related to being caught off guard: - In the short story, Love Comes Unprepared, the element of love was full of a feeling of being caught off guard. For example, in the interaction between Lin Xin and Liu Jiajing, Liu Jiajing started the conversation with " because I'm handsome." Later, in their interactions, there were many such unexpected moments, such as the sudden brake on the bus causing Lin Xin to fall into Liu Jiajing's arms. This kind of unexpected plot was a major feature of the novel. - In some novels, the author would be caught off guard. For example, the description of champagne-colored rose petals extending from the garden to the room was censored because the words "go" and "bed" were too close to each other. Using the names of famous people in modern history, borrowing events from special historical periods, adding religious characters to villains, using characters with special abilities, and the collapse of character settings would all make the author face the risk of review problems and even sealing the book. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The kindergarten did not pay social security
It was the kindergarten's legal obligation to pay social security for its employees. If the kindergarten did not pay the social security, the employee could submit relevant evidence such as salary distribution records when applying for labor arbitration to prove that there was a labor relationship between the two parties and request the relevant unit to pay the social security. However, there were some private kindergarten claims that they did not pay social security for reasons such as asking employees to sign a voluntary surrender of social security, paying after three years of employment, not being able to open a social security account without a record in the labor bureau, not paying social security quotas, only paying social security to the head teacher, young teachers after 2000 not paying social security, etc. However, these reasons did not comply with the national laws.
