If you're going to lecture on photographyIf the topic of the lecture was photography, one could start from the following aspects:
* * 1. Basic Knowledge **
1. * * Photographic Equipment **
- For beginners, the first thing to do was to introduce common photographic equipment, such as mobile phones and single-lens reflex cameras. Mobile phones had the advantage of being portable. Nowadays, many mobile phones had very powerful camera functions, with multiple shooting modes and automatic optimization functions. DSLR cameras could provide higher image quality and more manual operation options. For example, the lens could be changed to suit different shooting scenes (such as wide-angle lens for shooting large scenes, telephoto lens for shooting distant objects, etc.).
2. * * photography terms **
- Explain some basic photography terms, such as aperture, shutter speed, depth of field, etc. The size of the aperture affected the amount of light entering and the depth of field. A large aperture (small value) could blur the background and highlight the main body. At the same time, there was more light entering, which was suitable for shooting in dimly lit environments. A small aperture (large value) had a large depth of field and clearer front and back scenes. The shutter speed determined the length of the shot. A high-speed shutter could capture fast-moving objects, such as athletes on the sports field, while a low-speed shutter could capture the trajectory of objects, such as the silky effect of flowing water. Depth of field referred to the clear range between the background and the background in the shot.
* * 2. Shooting Techniques **
1. * * Composing Skills **
- Center composition: Place the subject in the center of the picture. This composition is simple and direct, and can highlight the subject. It is often used for close-ups of people or scenes that need to emphasize the subject.
- Diagonal composition: Placing the main body or important elements on the diagonal of the picture can increase the dynamic and extended feeling of the picture, making the picture more vivid.
- [White space composition: Leave a large area of blank space in the picture, usually a single-color background. This can create a simple and ethereal mood, making the main body more eye-catching and have the charm of traditional Chinese painting.]
- * * Foreground frame composition **: Use the elements in the picture to form a frame and frame the main body. It can enhance the layering and spatial sense of the picture and guide the audience's attention to the main body.
2. * * Use of Light and Shadow **
- Backlighting: Backlighting can make the outline of the object clearer. For example, when shooting leaves, backlighting can make the texture of the leaves clearer and more realistic. However, one had to pay attention to the intensity of the light when shooting against the light. The light against the light in the morning or evening was softer, and it was not easy to be exposed.
- Side Light Shooting: Side Light can produce a clear contrast between light and dark, creating a three-dimensional effect of the object. It is suitable for shooting people, buildings, and other objects.
- * * Using light and shadow to create effects **: For example, using the gap light in the background to form light spots to increase the interest and artistic sense of the picture.
3. * * Focus Technique **
- Explain the concept of focusing, which is to click on the phone screen or camera viewfinder to determine the clear point before pressing the shutter. When the subject was relatively simple and the background was not messy, it was relatively easy to focus. Just click on the subject. However, if the shooting scene was more complicated, such as there were many similar elements around the subject or the background was chaotic:
- For most phones (Android and Apple), you can focus on a place where the leaves are sparse and the background is not messy.
- Android phones could also use professional mode, switching from autofocus (AFF) to manual focus (MT), and adjusting the zoom parameters to make the subject clear.
* * 3. Shooting subject and creativity **
1. * * Choose the subject **
- Not only could he choose beautiful scenery as the subject, but sometimes strange subjects were more likely to leave a deep impression on the readers. For example, if you were to take a picture of a mantis with a comical expression, the unique subject would make the photo stand out even more.
- He could also make the subject bigger. This was the simplest, most effective, and most direct way to highlight the subject. For example, if he shot a butterfly on a flower, it would be easier to attract the audience's attention if the proportion of butterflies in the picture was larger.
2. * * creative shooting **
- You can add some creative elements when shooting. For example, when shooting animals, you can capture interesting moments, such as the moment when the praying mantis turns its head. Or like shooting a Chinese knot and a crescent moon, creating a unique artistic conception through the combination of different elements.
* * 4. Common problems and solutions **
1. * * Backstory processing **
- If there is no photography background, you can use the sky or wall as the background to avoid strange things in the background and keep the background clean. If there was a photography background, one had to pay attention to the amount of the background. Don't let the background cover up the main body. For example, when shooting a castle in the water, if there were too many water plants in the background, it would affect the performance of the main body. You could reduce the proportion of water plants in the picture, so that the photography background was a little thinner and thinner, thus emphasizing the main body.
2. * * Shooting small animals **
- When taking pictures of small animals such as insects, one needed to move the phone or camera closer to reduce the depth of field, blur the background, and focus on key parts such as the insect's eyes so that the details of the insect's head and its surroundings could be seen.
* * 5. Practicing and Practicing **
1. Students were encouraged to practice shooting in class or after class, such as setting specific shooting topics, such as "light and shadow on the street" or "corner of the campus", so that students could shoot and create according to what they had learned.
2. They could organize students to share their work and comment on it. Through communication and feedback, they could continuously improve their shooting skills.

But now you're going crazyThe word 'defection' had the meaning of rebellion, betrayal, defection to the enemy, change of heart, and not fulfilling the original agreement. However, based on the description of " now crazily defecting," it was not clear what the specific target was, whether it was an individual, a group, or something else. It was impossible to give a more detailed and accurate explanation.

He's going to fight backAs he did not know who " he " was and under what circumstances he would counterattack, he could not give a more specific answer. If it was a counterattack in the face of provocation, one could remain calm and confident, using humor to resolve, questioning, or a positive response. If it was a counterattack between countries, for example, China announced a ban on the export of rare earth processing technology, which was a counterattack against the U.S. led restrictions on the sale of advanced chips to Chinese companies. More background information was needed to answer accurately.
