As a beginner photographer, you need to know What is F-Stop: How Does IT Work in Photography? F-Stop is a very important fact in photography which you need to know to make yourself a next level photographer.

If you are a beginner photographer then you might have heard F-Stop or F-number. Here we will describe all things about F-Stop in detail.

Aperture

Before understanding F-Stop: How Does It Work in Photography? you need to know about aperture. Aperture is a hole in-camera lens that use to pass the light to the camera sensor. It works through some blades which we call aperture blade. If you see in your lens then you’ll see these blades make a small hole. This hole size is controllable by you. If you want to control this hole then you have to change your cameras aperture settings.   

In your camera, if you check the aperture settings then you can see it’s given like f/1.4, f/1.8, f/2.8, f/3.5, f/4, f/5.6, f/6.3, f/7.1, etc. Due to change this value you can control your aperture.

Why Aperture is Important

Often you’ll hear from other photographers stop down (close) & Open up (widen) the aperture for taking particular photos. Why they tell this! Because of due to change the aperture settings you can control the light & shallow depth of field.

If your aperture is big that’s mean your aperture value will low. One the other hand, if your aperture is small that’s mean your aperture value will high.

What is F-Stop

You can see in your cameras the LCD screen, some value has written with an “f” letter. That’s all value is the f-stop. F-Stop is looked like f/1.8, f/2, f/2.8, f/4, f/8, etc. Due to change F-Stop, you can control the brightness of your photography.

The lower number of F-Stop value means a bigger aperture & a Higher number of F-Stop value means a smaller aperture.

What does “f” stands for? 

Very simply f-stop’s “f” stands for focal length. If you change the f-stop value then the size of the aperture blades diameter will change.  For example, you have a 70-200 mm lens. When you take a photo at fully zoomed out 70 mm f/4 at that time your lens diameter will look exactly 20 millimeters. If you take a photo at f/16 at the same focal length your lens diameter will 5 millimeters. It’s mean higher F-Stop makes lower diameter.

There is a very simple equation to understand the F-Stop. If you buy two same size cake & cut a cake in 1/4 piece & cut another cake 1/8 piece. Then your 1/4 size cake piece will much bigger than 1/8 size cake piece. So, now you can easily understand that F-Stop f/1.4 is much bigger than f/4, f/8 or f/16. F-Stop f/1.4 passing more light & create more depth of field then F-Stop f/2.8, f/3.5, f/4, f/5.6, f/6.3, f/7.1, etc.

Relation between F-Stop & Depth of field

Now most of the wedding, portrait & fashion photographers highly like shallow depth of field in their photography. If your choice is the same & wants to make the shallow depth of field in your photography then need to understand F-Stop. Lower f-stop value makes the creamy shallow depth of field. On the other hand, higher f-stop value to make your image sharp.

If you want to take a sharp wide-angle nature image then your F-Stop should be f/8 or more. A higher number of F-Stop make your picture sharper where everything of that picture you can see clearly.

Low F-Stop number is cause for high shallow depth of field. If you take a pic at f/1.4 then the background of your subject will so blur. The same picture if you take at f/2.8 then it’s blur will reduce some level.

Which F-Stop values best to set

Different F-Stop value has a different importance. Now photographers spend a couple of hundred dollars more to get a maximum aperture lens like f/1.2, f/1.4, f/1.8, f/2.8, etc. Maximum aperture lenses can create background blur. 

There is no fixed F-Stop to set to take a perfect photo. It’s a photographer’s choice as their requirement of photography.  

Conclusion

If you have proper understanding, What is F-Stop: How Does It work in photography? then you can control brightness & depth of field of your photography.

Though F-Stop is not only working for brightness & shallow depth of field although it has a lot of other aspects of use. But as a beginner, you have to know these two first. Because these two are the major reasons to understand F-Stop.
