Natural Speed (Use of Shutter Speed)
Shutter speed is the duration of time in which light is allowed to pass through an aperture to expose the film. Shutter Speed is indicated by intervals such 1/60 or 1/100. For example, the interval 1/100 symbolically means that the shutter curtain opens and closes in one hundred of a second for one exposure. Thus, to expose the film with more light it would be appropriate to leave the shutter open for longer, thus, using a slower shutter speed. However, shutter speeds can be used for other purposes, not only for extra exposure or less exposure. If an object is in motion, capturing a photo can be difficult; yet, using a high shutter speed would allow a clearer photo to be observed. Since it takes less time to expose the film to the light, the action being observed would seem to freeze and appear clear.
The first photo taken depicts a plant with a lit incense stick. The low shutter speed used to capture the incense stick produces a visible white smoke, which creates a billowing visual display.
The second and third photos shows water being poured into a vase. The differing shutter speeds allow one to notice the difference between the exposure times and see the effects of a higher shutter speed compared to that of a lower shutter speed. The droplets seem to freeze in mid-air when exposed with a faster shutter speed.
