There are many ways to manipulate the content of photos or videos to create false impressions and mislead the public. Common methods include: 1. **Image editing software**: Using image editing tools such as Photoshop, it is easy to modify elements in photos, such as adding, deleting or changing the color, shape and position of objects, to create misleading visual effects. 2. **Selective editing**: Selectively editing certain clips in a video can change the original meaning of the event. For example, by editing out contextual information, the audience may mistakenly believe that a certain speech or behavior has a different intention. 3. **Fake news and false information**: Creating false pictures or videos with misleading titles or descriptions can cause audience misunderstandings. For example, if a doctored photo is combined with a political event, it may cause the audience to believe some false plots. 4. **Deepfake technology**: Deepfake videos generated using artificial intelligence technology can give one person's face or voice to another person, thereby creating a false scene that looks real, which may be used to discredit individuals or mislead the public. 5. **Encapsulated information**: By editing and refining complex events into simple short clips, it is easy for the audience to misunderstand the true situation of the event. For example, simplifying a complex social issue into a single, easily spreadable image or video. 6. **Social media communication**: Rapidly spreading edited content through social media, driving viral spread, allowing more people to see and share, thereby deepening misunderstandings. 7. **Exploiting emotions and cognitive biases**: Creating emotional content that exploits the audience's cognitive biases (such as confirmation bias) to make them more likely to accept false information that is consistent with their existing beliefs. To prevent being misled, the public should maintain critical thinking, verify the source of information, and carefully analyze suspicious images and videos.
