How many pixels does it take to shoot a retro camera?

A camera with retro atmosphere needs 2665438+ ten thousand pixels. A camera is a kind of equipment that uses the principle of optical imaging to form an image and records the image with a negative. This is an optical instrument used for photography. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging devices and astronomical observation devices.

Camera introduction

There are many kinds of cameras, which can be divided into landscape cameras, printing and plate-making cameras, camera file microfilm cameras, microscope cameras, underwater cameras, aerial cameras, high-speed cameras and so on. According to the size of photographic film, it can be divided into 1 10 camera, 126 camera and 135 camera, and it can be divided into perspective camera and dual-lens reflex camera according to the way of framing.

Any classification method cannot include all cameras, and a camera can be divided into several categories. For example, 135 camera forms a complex spectrum according to its different ways of framing, shutter, metering, film transmission, exposure, flashing, focusing and self-timer. The camera uses the linear propagation characteristics of light and the laws of refraction and reflection of light.

From the function of photography, a camera should have three structural systems: imaging, exposure and assistance. The imaging system includes imaging lens, ranging and focusing, framing system, additional lens, filter, effect mirror and so on. Exposure system includes shutter mechanism, aperture mechanism, metering system, flash system, self-timer mechanism, etc. The auxiliary system includes film winding mechanism, counting mechanism and film rewinding mechanism.
