Is the camera daylight saving time off or on?
If your country has set up daylight saving time, then of course it is better to turn it on, so that it can be consistent with the actual time and more convenient. If your country does not set up daylight saving time, turn it off, otherwise it will easily cause time confusion.
A camera is a device that uses optical imaging principles to form images and uses film to record the images. It is an optical instrument used for photography. In modern social life, there are many devices that can record images, and they all have the characteristics of cameras, such as medical imaging equipment, astronomical observation equipment, etc.
After the light reflected from the scene being photographed is focused through the photographic lens (objective lens) and the shutter that controls the exposure, the scene being photographed forms a latent image on the photosensitive material in the camera obscura, which is processed after processing (i.e. Development, fixation) to form a permanent image. This technology is called photography, which is divided into general photography and professional photography. In September 2018, the World Customs Organization’s Coordination System Committee classified drones as “flying cameras.”
With the advent of the dry plate camera in 1879, photography became more popular. Lens design underwent significant development at the end of the 19th century. In the early days, designers were able to design lenses with large apertures but small shooting angles. By this time, the need for large apertures and wide angle shooting had been raised by photographers. Professor Petzval realized that in order to design a wide-angle lens, one must first solve the problem of astigmatism at the edge of the image field. Unfortunately, the types of glass available at the time could not meet the needs of designers.
