CAMERA BASICS - (SHUTTER SPEED)













Being best in the art of photography is what is considered “in” in the modern world. Many imbeciles are making constant efforts to develop their skills so that their usual random clicks differ from that of an amateur. And well there’s nothing wrong with the new obsession, after all one should excel in the art of photography if
their passion was big enough for them to motivate and splash literally a whole fraction of their monthly salary on it.Photography is a cool occupation, an expensive hobby and a hell of an engrossing exercise if one is up to learn the nitty-gritty details to brush up their skills.














While beginning to learn about the fundamentals- Shutter speed is one of the most basic features to start with. To begin with the basic explanation the shutter speed of a camera is the factor that determines for how much time interval the lens will be exposed to the light. It is this factor pooled together with f-number and nature’s own luminance that determines the quantity of light that reaches the image sensor. A single quantity that measures the f-number and shutter speed is called the Exposure Value (EV).
Working Shutter Loopable Now let’s begin to understand with the working of it and the crucial role the shutter speed plays after the aperture and ISO do their work. Everyone knows that we see any object when it reflects light from its surface, as one picks up a camera to shoot imagery and presses the shutter button, the object gets into our camera in the form of a light. The amount of light that initially travels depends on the source of it that is, if it is too bright or dim, it reaches the lens aperture via various optical devices and finally strikes it- this is now when the shutter opens in a matter of milliseconds allowing the light to hit the image sensor for only a specified period of time. The duration directly depends on what type of source the light was
coming from. If the source was bright with ample amount of light emerging from it then the shutter speed is set really fast (around 1/8000th of a second) so that not even an iota amount of excess light reaches the image sensor and ruins the image by burning or overexposing it. On the other hand, if the source of the light is
too dim the shutter speed is slowed down (to around 30seconds) so that sufficient amount of light for a decent brightness image passes the aperture to reach the sensor. Here even aperture adjusts its size each time- from small to large diameter depending upon the former or the latter situation.
