What are the dangers of long exposure photography?Long exposure photography may have the following dangers:
1. ** Shaking caused by anti-shake system **: When the camera is placed on a tripod for a long exposure, if the anti-shake system is turned on, the camera may misjudge and try to compensate for non-existent shaking, resulting in shaking or blurring.
2. ** Reflective Plate Causes Vibrations (DSLR)**: When a DSLR camera takes a long exposure shot, the movement of the reflective plate when the shutter is pressed will cause the body to vibrate slightly, which may cause the photo to be blurred.
3. ** Image Quality Decline **: When the aperture is set to f/22 or lower to extend the exposure time, the sharpness of the image will be greatly reduced due to optical refraction.
4. ** Increase noise **: Exposing for a long time under high sensitivity may increase noise, resulting in a decrease in image quality.
5. ** Damage to the shutter system **: If the shutter is still open when the battery is dead, or if the camera is turned off and then turned on during the shooting process, it is not good for the shutter system. Moreover, every exposure of the camera has an impact on the life of the camera. Although the damage of the exposure duration under normal use is minimal, the special light source or long-term exposure under strong light may cause damage to the camera.
6. ** Rising temperature of the sensor (professional camera)**: Prolonged exposure of a professional camera may cause the temperature of the sensor to rise, affecting performance and even temporarily burning. Therefore, you must pay attention to heat dissipation and control the time reasonably.
7. ** Danger of lens damage **: If the lens cover is not properly closed during long exposure, dust or small bugs may enter and damage the lens.

The dangers of watching horror movies for a long timeLong-term viewing of horror movies may have the following dangers:
1. ** Physiologically **
- It had adverse effects on the cardiovascular system. Horror movies would stimulate one's vision and hearing. When this stimulation was transmitted to the brain, it would cause the human body's heart rate to increase, breathing to accelerate, blood vessels to contract, and blood pressure to rise. At the same time, scary scenes and music can cause the secretion of galloping substances in the human body to increase, increasing the instability of the heart, and easily causing serious heart rhythm disorder. For people with pre-existing cardiovascular and cardiovascular diseases (such as elderly people and teenagers with potential cardiovascular and cardiovascular diseases, such as congenital cerebral venous anomalies, congenital heart diseases, or heart diseases related to genetics, etc.), accidents may occur when encountering such strong emotional stimulation, such as inducing heartache, myocaricola, cerebral venous rupture, cerebral hemorrhage, etc.
2. ** Psychologically **
- It caused negative emotions. Long-term viewing could lead to the accumulation of negative emotions such as fear, nervousness, anxiety, and so on, affecting one's mood and daily life.
- Causing a change in behavior. They might not dare to sleep alone, go to the toilet, and have nightmares and talk in their sleep, affecting their sleep quality and daily life.
- It brought about cognitive problems. If one was immersed in it for a long time, it might affect their cognitive ability, especially for children and teenagers. Due to their limited cognitive ability, they might not be able to distinguish between the fictional plot in the movie and real life. As a result, the horror scenes would not disappear in their minds for a long time, causing unnecessary fear and worry.
- Increases the risk of mental illness. In severe cases, it could lead to mental illnesses such as night terrors and agoraphobia, affecting mental health, social skills, and quality of life.
