Photography exam: What is the function of shutter? A controlling the amount of light, b controlling the time of light, c affecting the junction aberration, d adjusting the color temperature, e affecting the image definition. The role of the shutter: A controls the amount of light entering, B controls the time of light entering, and E affects the imaging clarity.

The following analysis:

C affects the kink aberration d, adjusts the color temperature f, and controls the depth of field.

These three are respectively; The influence of lens and aperture, the role of fuselage (or film) and the role of aperture need not be mentioned here.

Let's start with the tangled questions: a and e.

A control light: many people don't choose this one either, thinking that it is aperture controlled. In fact, the combination of shutter and aperture is the real control of light. If the amount of light is controlled in unit time or the same shutter time, it is only an aperture. So to control the amount of light, then this also includes the role of the shutter.

But this place is really tangled. Where is it? This depends on how to define this amount of light, is it just the amount of light entering the lens or the amount of light entering during exposure? If we are talking about the amount of light entering the lens, then the shutter only participates in the amount of light entering the exposure, not the amount of light entering.

Therefore, this topic does not specify the amount of light entering, which can be considered as a general statement. Of course, the shutter can participate in the control of the amount of light entering.

E affects imaging clarity: Many people will not choose E because it will be associated with the problem of aperture controlling depth of field. But relatively speaking, the shutter does affect the imaging clarity, such as the safe speed of the lens and shutter when holding a camera. Noise problems caused by long exposure.
