Camera Fun Facts 🦍 "Shutter Speed"
Let's briefly explain what exposure is first! In essence, photography is an exposure process that uses different mediums to record the image seen through the lens at that moment. The mediums used can generally be divided into three types: film (analog), CCD (digital), and CMOS (digital). We'll discuss this topic in more detail if given the chance.
The shutter is essentially a device placed in front of the film, CCD, or CMOS. Its function is to limit the exposure time for each photo. In dark scenes, where less light enters, it's perfectly fine to use a longer exposure time. However, if there's no shutter to limit the exposure time during bright daylight, it will result in overexposure, where the entire photo appears trắng and nothing can be seen! Conversely, a shutter speed that is too fast, allowing too little light, will cause underexposure.
The shutter speed is inversely proportional to the exposure amount. A faster shutter speed means less light can enter the camera body. You'll usually see shutter speeds expressed as fractions. For example, 1/125 actually means the photo will complete the entire exposure process in 1/125 of a second.
Of course, you might ask, what's the relationship between different shutter speeds then?
It's actually very simple, just like primary school math when counting pizza slices. 1/250 is half of 1/125, so the exposure of 1/125 will be twice that of 1/250. This means the photo will be twice as bright!
That's all for now. See you next week, bye!
