What are the professional terms for industrial cameras?

generally refers to the plane where the imaging material is located. The light passes through the lens and is focused on the imaging plane, resulting in a clear photo.

refers to the distance between the lens and the film. If the focal length is appropriate, the light reflected by the scene can be concentrated on the imaging plane through the lens and become a point. If the focal length is inappropriate, it will become a circle, causing the photo to be blurry.

When the shutter is open, light passes through the lens, passes through the aperture, enters the darkroom, and finally shines on the imaging material. This process is called exposure.

Exposure refers to the amount of light in one exposure. If the exposure is too low, the color of the photo will be dark, if the exposure is too high, the color of the photo will be white, and if the exposure is too low or too high, the details in the photo will be lost. Exposure is usually determined by a combination of aperture value and shutter speed.

refers to the size of the darkroom window. The lower the aperture value and the larger the window, the more light will penetrate, causing the exposure to increase, and vice versa.

refers to the time the shutter is open. If the shutter speed is slower, the longer it is open, the more light will penetrate, causing the exposure to increase, and vice versa. If the subject is a moving object, a faster shutter speed is required.

refers to the front-to-back distance at which the scenery in the photo can be clearly displayed. In landscape photos, a large depth of field is required. A smaller focal length can obtain a larger depth of field.

There are two types of zoom in digital cameras: optical and digital. Optical zoom uses lens movement to enlarge and shrink the scene to be photographed; digital zoom simply crops the image captured by the CCD.

refers to the photographer manually specifying an aperture value, and the camera automatically calculates the exposure mode corresponding to the shutter speed based on the metering results. It is suitable for scenes where depth of field needs to be controlled.

refers to the photographer manually specifying a shutter speed, and the camera automatically calculates the exposure mode corresponding to the aperture value based on the metering results. It is suitable for shooting scenes of fast-moving objects.
