Aperture and f stop12/12/2022 ![]() ![]() ![]() From the practice and knowledge you would of gained from that style of shot demonstrated in the images above you will have an understanding of what aperture values you want to shoot with and there overall effect.Īn example of when you would use a narrow aperture would be landscape photography. As you have seen in the images above at F1.7 you could focus on the eye of your subject. The wider aperture (low F-number) will create a shallow depth of field, making only the subject in focus. When would you use a wide aperture?Īn example of when you would use a wide aperture would be portrait photography. You can learn which aperture values you prefer and like to shoot with and how they can create your style of photography. In these type of shots you can really play around with the aperture values and you will begin to understand there limitations and how subtle they can vary. You can clearly see how the effect has changed from the previous image and more of the lenses are now in focus but like the other image shot at F22 (second picture down) it does not really effect the overall image if the focus was on the first or second lens at F22 as so much of the foreground is in focus. The focus was set to the second lens on the focal range (45-150) using the aperture value of F22. The above image shows the effect of a narrow aperture or high F-number. You can clearly see the effect and how you can begin to be creative using different aperture values and focusing on different parts of your subject. The focus on this image was set to the second lens on the focal range (45-150) using the aperture value of F1.7. The above image shows the effect of a wide aperture or low F-number but like the two previous images above. You can clearly see how the effect has changed and more of the lenses are now in focus. The focus was set to the first lens on the focal range (14-42) using the aperture value of F22. The focus was set to the first lens on the focal range (14-42) using the aperture value of F1.7. The above image shows the effect of a wide aperture or low F-number. The narrow apertures (high F-numbers) will contract and allow less light into the lens and will provide a deeper depth of field meaning your whole image, background and the foreground, can be in focus. ![]() When the aperture is wide (low F-number) it will expand and allow more light into the lens and will provide a shallow depth of field, the background of the image will appear blurrier. ![]() Narrow aperture = High F-numbers = Deep depth of field = Sharper background.ĭepth of field = The distance between the nearest and furthest objects giving a focused image.įoreground = The part of a view that is nearest to the observer.īackground = The part of a view that is furthest from the observer. Wide aperture = Low F-numbers = Shallow depth of field = Blurrier background. The wider the aperture the smaller the F-stop number. The F-stops, F-numbers express the size of the lens opening. The Aperture controls the amount of light that passes through the lens that is contracted or expanded like the iris in the human eye. In photography Aperture or Aperture value is also known as an F-stop or F-number. ![]()
