How many suitable lenses should be chosen for the focal length?The focal length of the lens depended on the shooting requirements:
1. ** Portrait Shooting **:
- For close-up portraits, 85mm was a better choice because the facial features displayed at this focal length were more natural. Compared to wide-angle lenses, it would not cause the facial features of the character to be distorted, and compared to telephoto lenses, it could make the facial features of the character more three-dimensional. However, when taking a close-up portrait with a focal length of 17mm, the object closer to the lens would be magnified due to the wide angle. It was easy to cause the parts close to the lens such as the mouth, nose, and arms to be deformed, and the ratio of the character to the background would be more exaggerated.
2. ** Daily Shooting (The angle of view is similar to the human eye)**:
- The focal length of a standard focal length lens was about 50mm. The angle of view of this type of lens was similar to that of the human eye. It was small in size and had a large aperture. The technology was usually more mature and the sales volume was high.
3. ** Zooming lens requirements (requires flexible focal length adjustment)**:
- The focal length of a zoom lens was generally between 28 - 200mm. It could continuously change the focal length. One lens could replace a variety of lenses with different focal lengths, and it could continuously change the scene by continuously changing the focal length, forming the effect of pushing and pulling the lens. Common zoom lenses were 12mm-75mm (6x), 10mm-150mm (15x), 9.5mm -143mm (15x), and so on. If the focal length marked on the lens has two numbers (such as 24 - 70mm), it means that this is a zoom lens, and its focal length can be adjusted between these two numbers; if there is only one number (such as 50mm), it is a fixed-focus lens, and it can only be fixed at this focal length.
4. ** Wide-angle effect (requires a wider angle of view and more framing elements)**:
- The smaller the number, the shorter the focal length, the wider the angle of view, the wider the viewing range, and the more elements the picture contained. For example, a focal length indicator such as 17 - 40mm indicated that this was a zoom lens. At the 17mm end, a wider angle of view could be obtained. It was suitable for scenes that required a large angle of view and multiple elements, but the proportion of each element was small.

Has Huanhuan finally chosen the number?Yes, Huanhuan had finally chosen the number. The three forces behind the scenes (President Fang, Deputy Mayor Li, and Eunuch Tian Yulan) were sent to help Huanhuan at the same time. In the end, Xia Huanhuan was able to enter the selection.

Paving a path in kindergarten and reflecting on the middle classThe following is a lesson plan and reflection for the kindergarten middle class:
##1. Activity Target
1. Understanding the shapes: Square, triangle, circle, and initial perception of the conversion relationship between semicircle and circle.
2. During the activity, the children were allowed to carry out mathematical operations according to the teacher's requirements.
3. Stimulate children's interest in mathematics activities.
4. Guide the children to interact with the materials and experience the fun of math activities.
5. To develop children's logical thinking ability.
##2. Event preparation
A duckling headdress, a path made of various geometric shapes, and a five-pointed star.
##3. Activity
1. ** Watch the scene performance import **
The duckling fell on the way home. He guided the children to think about the reason why the duckling fell, and then asked the children to help the duckling pave the road.
2. ** Paving Paths **
- He observed the shape of the pit in the path. Ask the child to find out the shape of the pit, then fill it with stones of the same shape as the pit, and check if it is filled and the size is just right.
- The teacher guided the child to carry out the operation activities and filled in the shapes one by one.
- Show two semicircles and guide the children to discuss where to put them. From there, it can be concluded that two identical semicircles together form a circle, and a circle can be divided into two identical semicircles.
3. [Game: Stepping on Stones]
The teacher showed a figure and asked the child to quickly stand next to the figure to see who found it right and fast.
4. ** Game over **
The children sent the duckling home together.
##IV. Reflection on the Event
1. ** The teaching method is reasonable **
According to the spirit of the outline, we should reasonably use various educational and teaching methods to organize teaching, and use the three inseparable teaching methods of operation, exploration, and observation to break through the important and difficult points of the activity. Through exploration, children could gain perceptual experience, arouse curiosity, think actively, and discover and solve problems.
2. ** Teacher role positioning is accurate **
In the activity, the teacher played the role of a guide, a collaborator, and a supporter, and the child became the main body of learning. For example, in the process of paving the path, the teacher guided the child to observe and operate, and gave guidance when the child encountered difficulties.
3. ** Follow the educational philosophy **
Following the step-by-step education philosophy, he guided the children to learn and play. The activity went from watching the duckling wrestling to the task of paving the path, to understanding the relationship between the shapes in the path, and then to consolidating the knowledge through games. The children were very interested in the activity and were very motivated to learn. They mastered the knowledge they had learned through playing and games.
