You are thinking about buying lenses. While looking at the lens reviews, it provides the advantage of shooting up to four stops. Lens comparisons also have 2 stops advantage compared to the other writes. You want to get a filter, you are looking at the reviews or explanations, it provides an advantage up to 10 stops. You upload photos to photo sharing sites and people comment that you are exposed to 1 stop less. So if you are wondering what this f-stop is, please read the rest of our article.

What is F Stop?

Basically, the determination of each step change value of aperture, shutter speed and ISO values, so the amount of light falling on the sensor is called stop.

what is f-stop and how it works?

What is Aperture?

If you remember from our article, aperture values ​​are like f / 1.2 – f / 1.4 – f / 1.8 – f / 2 – f / 2.8 – f / 4 – f / 5.6 – f / 8 – f / 11 – f / 16… In this case, there is a stop difference between f / 1.4 and f / 1.8. In the orther articles, we emphasized that the amount of light reaching the machine changes 2 times with each f interval change.

Similarly, in our article about shutter; the values;
Values ​​below 1 second are 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1 / 4000, 1/8000

Those which over 1 second they received the values ​​of 2, 4, 8, 15, 30. Just like the aperture in shutter, each value jump means to expose 2 times of light in each stop. 1/250 shutter value will gain 2 times more light than 1/500.

Note that there is an inverse proportion between the aperture and shutter speed. If you take a photo with f/2 aperture and 1/60 shutter value and if you take the same composition with f/1.8 and 1/60 shutter speed or f/2 aperture 1/30 shutter, you will be overexposed by 1 f-stop.

what is iso?

In all these exposure settings, you can think of ISO as a balancing factor. By increasing the ISO, we help balance the exposure and provide an advantage to our photography until the required stop.
