Choosing the index of the camera lens
When choosing a camera lens, there were several factors to consider: ** 1. In terms of optical quality ** 1. ** Sharpness ** - Sharpness was the ability of the lens to reproduce details on the focal plane, which was the clarity of the edges and texture of the object in the image. High sharpness allowed the image to be clearer and finer, making it easier for the viewer to see the subtle differences. Excellent lenses had first-class optical design, materials, and lens grinding standards. They had good sharpness within the focal range. Fixed focus lenses, especially top-notch fixed focus lenses, had better sharpness. However, the sharpness of macro lenses was very outstanding among all lenses. 2. ** Distortion ** - The lens distortion was the distortion of the straight line in the image after the image was formed. It was common in wide-angle and zoom lenses, but almost all lenses had it more or less. Whether the lens had obvious distortion was an important indicator to measure its quality. 3. ** Dispersion (Color Deviation)** - When light passed through the lens, the refraction index of different colors of light was different. They could not converge perfectly at the same point on the imaging plane, and color stripes would appear at the edge of the high-contrast area of the image, such as "purple edge" or "green edge". Therefore, it was necessary to consider whether the lens was prone to this situation in high-contrast scenes. 4. ** Dazzling lights and ghostly shadows ** - This was directly related to the quality of the lens coating. A well-coated lens was not easy to produce glare or ghostly shadows under strong light. 5. ** Dark corner ** - It mainly depended on whether the lens had obvious dark areas under the large aperture. It was even more important to pay attention when using it on a full-frame body. 6. ** Fade out of focus ** - The beauty of the void-out was an important indicator. A good lens would take a photo where the out-of-focus part of the scene was evenly spread, the color gradually changing naturally and evenly, and the transition between in-focus and out-of-focus was natural. Some high-end lenses such as Canon EF200mmf/2L IS USM and Nikon AF-S 200mmf/2G ED VR II had outstanding out-of-focus imaging effects. 7. ** Image resolution ** - It refers to the ability of the lens to reproduce the subtle structure clearly. The higher the resolution, the stronger the ability to show the subtle differences in the image. It is more meaningful for digital cameras with higher frame factor. It could be measured by taking a black-and-white fringe pattern with a high-resolution photographic medium and analyzing it. 8. **MTF Value (Modality Transfer Function)** - This was a comprehensive evaluation of the sharpness, contrast, and resolution of the lens. ** 2. The material of the lens ** 1. [Durability] - Metal was usually stronger and more durable than plastic, but it was heavier, more expensive, and consumed more power when auto-focusing. In addition to the material itself, it also depended on the overall workmanship of the lens, including whether the vibration of the zoom ring and the focus ring was appropriate, whether the operation was smooth, and whether it was waterproof and dust-proof. This was very important for outdoor shooting. ** 3. In terms of autofocus performance ** 1. ** Focus Speed ** - The focusing speed of the lens under different lighting conditions was an important consideration. 2. ** Focus accuracy ** - Pay attention to whether there is a problem with the front and back focus (the focus "bellows" problem). 3. ** Focus noise ** - In video shooting, silent focus was especially important, so whether there was obvious noise when the lens was focused also needed to be considered. ** 4. Other aspects ** 1. ** Aperture size ** - The size of the aperture affected the amount of light entering and the depth of field effect. For example, the aperture value was marked with the letter f. The smaller the f, the more blurred the background of the subject and the lighter the depth of field. For a fixed-focus lens, a larger aperture could be achieved at a lower manufacturing cost. 2. ** Is it a constant aperture (for zooming lenses)** - A constant aperture lens could use its nominal maximum aperture at all focal lengths. 3. ** Focus Type (Fixed or Zoomed)** - The optical design and mechanical structure of the fixed-focus lens were simple, which could achieve higher image quality, larger aperture, and lighter weight at a lower cost. The zoom lens was more flexible in focal length adjustment. For example, the 85mm fixed-focus lens was considered by many professional photographers to be the king of portrait photography. It had advantages in terms of shooting angle, shooting distance, image quality, etc., but it also had shortcomings such as a fixed angle of view. Read more exciting novels for free

Female Dormitory Electricity
The electricity bill in the female dormitory could be affected by many factors. First of all, the duration and power of electrical appliances were key factors. For example, if the air conditioner and water heater were not turned off day and night, the electricity bill would increase significantly. For example, some dormitories only used 200 yuan for 12 days because the air conditioner and water heater were running for a long time. Secondly, the illegal use of electrical appliances would also cause the electricity bill to double, such as using a hairdryer to roast sausages and cook instant noodles. In addition, the difference in electricity consumption habits of dormitory members would also affect the sharing of electricity bills. For example, some members were afraid of cold or heat, and the demand for air conditioning was high, while some members used less time, which might cause conflicts when sharing electricity bills. For example, some girls were criticized by their roommates for turning on the air conditioner and paid 4000 yuan for electricity bills in one go, while others were arguing about how to share the electricity bill due to the use of the air conditioner. Moreover, the accommodation fees of different dormitories included different services. Some dormitories might already include a certain amount of electricity, while others needed to pay extra. For example, some schools charged 600 yuan for eight people and 1200 yuan for four people. They also needed to pay extra for water and electricity.

How painful it is to love but not get it
Loving and not being able to get it was an extremely uncomfortable emotional experience. First of all, they would fall into a conflicted state of mind. They would miss each other every day, but they knew in their hearts that this love might not work out. This kind of contradiction would make people feel lost, helpless, and even hopeless. Secondly, they would become uncomfortable in front of the person they liked. The two people who originally got along naturally would become restrained because of one party's love. For example, in the past, they could pat each other on the shoulder and call each other brothers. After they liked each other, they would have mixed feelings when they got close to each other. They did not dare to open their hearts to express their love, afraid that they would not even be friends. Moreover, people who loved but couldn't get it often could only pay attention to each other silently. They were close but couldn't have it. It was like looking at the stars in the sky that were difficult to touch. When he recalled the good things in the past, his heart would still ache. He wanted to forget them, but they became clearer and clearer. All the memories lingered in his heart. There would also be situations where they would deceive themselves and persuade themselves to let go, but it would be difficult for them to do so emotionally. They would be deeply immersed in it and unable to extricate themselves. They would constantly hurt themselves like addicted drugs. Even if she wanted to give up, she couldn't let go because of the complexity of feelings. She was afraid of strangers when she was far away, afraid of being annoyed when she was close, afraid of being indifferent when she was less, and afraid of being entangled when she was more. When the relationship ended or he didn't get a response, he would fall into a state of being harsh on himself. He had to bear all the negative emotions while forcing himself to let go.
Setting up a DSLR for Taobao Video Shooting
Based on context alone The following are some basic settings for a DSLR camera when shooting Taobao videos: * * 1. Picture resolution and frame rate ** 1. * * resolution ** - For Taobao videos, full HD (1920 × 1080) resolution was usually enough to meet the demand. If your DSLR supports 4K (3840x2160) and your computer is equipped to process 4K materials, you can also choose 4K for higher definition. A higher resolution would have a better effect when displaying the details of the product. 2. * * Framerate ** - Under normal circumstances, a frame rate of 25 fps or 30 fps would be fine. This was a more common frame rate, and it looked smoother visually. If you needed to shoot slow-motion shots, you could choose a frame rate of 60 fps or higher and then slow down the scenes in post-production. * * 2. Focus Mode ** 1. * * Automatic Focus Mode ** - Most single-lens reflex cameras have multiple autofocus modes. For still commercial shooting, single-shot autofocus (AF-S or One-Shot AF) was more suitable. In this mode, the camera would lock onto the focal point after focusing once. It was suitable for shooting stationary products. - If you were shooting a dynamic display, such as a model walking around with a product, you could choose continuous autofocus (AF-C or AI Servo AF. The camera could continuously focus on moving objects. 2. * * Manual Focus ** - In some cases, manual focus might be more useful. For example, when the product has a special texture or a low-contrast surface, the autofocus may make a mistake. Manual focus can accurately adjust the focus to the position you want. * * 3. Exposures Setting ** 1. * * Aperture ** - The size of the aperture affected the depth of field. If you want to highlight the main body of the product and blur the background, you can use a larger aperture (such as f/2.8-f/5.6). However, it should be noted that a large aperture may cause the depth of field to be too shallow, and some details of the product may not be within the focus range. It needs to be adjusted according to the actual size of the product and the shooting needs. If you want to shoot a panoramic product or need the entire product to be clear, you may need to use a smaller aperture (such as f/8-f/16). 2. * * Shutter Speed ** - The shutter speed depended on the content of the shot, aperture, and the settings of the camera. In order to avoid blurring when holding a camera, the shutter speed should not be lower than the inverse of the focal length of the lens. For example, using a 50mm lens, the shutter speed should not be lower than 1/50 second. If it was in a dark environment, you could reduce the shutter speed, but you might need to use a tripod to keep the camera stable. 3. **ISO** - The higher the value, the more sensitive the camera was to light, but at the same time, it would also increase the noise of the picture. In the case of sufficient light, try to use a lower USB value, such as USB 100 - 400, to get a clean picture. If the light is dim, you can gradually increase the IQ, but pay attention to controlling the noise. * * 4. White Balance Setting ** 1. * * Automatic White Balance ** - In most cases, Automatic White Balance (AWB) could achieve more accurate color reproduction. However, if the shooting environment had special light colors, such as warm yellow lights or blue fluorescent lights, the automatic white balance might deviate. 2. * * Manual White Balance ** - If you need more precise color control, you can use manual white balance. You can take a picture of a white card (such as a piece of white paper) and then set this white color in the camera as the reference for white balance. This way, you can ensure that the color of the product is accurately displayed in the video. * * 5. Shooting Mode ** 1. * * Manual Mode (M)** - The manual mode allowed full control of the aperture, shutter speed, and the USB. It was suitable for users with a certain level of photography experience. When shooting Taobao videos, manual mode was a good choice if you wanted to accurately control parameters such as exposure and depth of field. 2. * * Aperture priority mode (A or Av)** - In this mode, the user could set the aperture size, and the camera would automatically adjust the shutter speed and USB according to the surrounding light (when the USB was turned on). It was suitable for shooting that focused on the depth of field effect. 3. * * Shutter priority mode (S or Tv)** - In Shutter priority mode, the user could set the shutter speed, and the camera would automatically adjust the aperture and the USB. If you need a specific shutter speed to capture motion or avoid blurring, this mode is more suitable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
