One of the terms that confuse numerous photography beginners is “Stops.” It is a very important expression in the photography world, as it is directly connected with the amount of light that reaches the camera’s sensor. “Light stops” means that, by using three essential camera tools, ISO, shutter speed and aperture, you double or halve the amount of light in the taken photo. A “stop up” is going to double the amount of light in your photo, whereas, going a “stop down” is going to halve the amount of light present in the image. Let’s take a look at how you should use the three crucial elements to take complete control over your light exposure.
Before we start, keep in mind that exposure and stops are two different things. Exposure is the amount of light the sensor is exposed to, whereas the term stop was invented to directly refer to doubling or halving the amount of light in images.
