Most people use the terms f-stop and aperture interchangeably.īut if we want to be very accurate and precise, the difference is in the definitions.įirstly, the f-stop meaning is the ratio between the focal length and the aperture blade diameter (f-stop = focal length/diameter as mentioned earlier). Well, if you break down what f-stop is, it’s essentially the same. In contrast, smaller apertures will only let in half the amount of light as the larger aperture.įor example, an f/2.0 f-stop will allow 800 lumens into the sensor, while the f/2.8 only lets half of the original amount (400 lumens) touch the sensor.īut what is the best setting for macro photography when you want a vivid background? In this situation, your saving grace is bracketing and stacking.īy now you may wonder, are the f-stop and aperture the same thing? Are Aperture and F-Stop the Same Thing? For landscape photography, it will be better to use smaller apertures ranging from f/8 to f/16.Ī larger aperture will allow more light to enter the lens and provide greater exposure. If your concept requires a shallow focus on your subject, choose a larger aperture (f/1.4 to f/4). Does your concept need a specific focus? Do you want to focus on the foreground only or the whole scene? Your choices of apertures should be suitable for your photography vision. ![]() We have a full guide on aperture if you want to check that out later. On the other hand, larger apertures will only focus on the foreground while blurring everything behind it. Smaller apertures will give a photo with throughout focus from foreground to background. Why Aperture is Important?Īperture will determine the focus and exposure of your image. No, but this extended information about the camera mechanism will come in handy when you take on a professional project with rigid requirements. Is it necessary to always count the diameter of the aperture blades in the lens? Using that example, we instantly know that the aperture blades will appear larger at f/1.4 and become ridiculously small at f/22. It means that the diameter of your aperture blades in the lens will be precisely 50mm. Then divide 200 by 4 (4 because it’s the max aperture), and you’ll get 50 as a result.į-stop is the ratio between the focal length and the aperture blade diameter If you have a Canon EF 70-200mm f/4 lens fully zoomed in, the aperture blades’ diameter will be 200mm. The answer is it stands for focal length. In contrast, when he/she recommends a smaller aperture, use the f/8, f/16, and so on.īut… What does the “F” even mean? What Does the F Stand For in F-Stop? The next time your mentor asks you to use a larger aperture, you should set your f-stop to f/1.4 to f/2.8. This metaphor perfectly explains why the smaller f-stop numbers (1, 2, 3, and 4) translate into a larger aperture and vice versa. When you cut the pizza into a half (½), you will have a larger portion than cutting it into one-eighth (⅛), right? To put it in practice, the f-stop of f/22 is equivalent to 1/22, and F/1.4 is the same as 1/1.4. Yet, the hint has been in front of us the whole time. We have all been confused with the smaller and larger aperture concept. So, how do you “count” the f-stop? And what’s the meaning of “larger” and “smaller” f-stops/f-number?
