![]() So, to answer the basic question: the f-stop - the size of the aperture - is the primary factor that makes a lens brighter or not, and different lenses at the same f-stop should give very close to the same results. In fact, since such lenses often have more glass in order to compensate for artifacts at wider apertures, the transmission might even be less. Most importantly, the t-stop isn't related to the maximum (widest) aperture of the lens - that is, it's not at all guaranteed that the lens with the widest maximum aperture will have the highest transmission. In still photography, it's usually just ignored. ![]() That's primarily useful in video, where you might need to keep exposure perfectly consistent when switching lenses. In the real world, other factors, like the amount of light absorbed by the glass also play in - for cases where it's important to know precisely, there's a thing called " t-stop". I say "approximately" because the f number is derived only from the ratio of the focal length to the size of the aperture. At f/1.8, both lenses will let in (approximately) the same amount of light. The above is the difference between large aperture and small aperture of the camera.However, someone has told me that if in both lenses I will use f/1.8 aperture, still the latter lens will have more light. We should adjust it according to the different subjects we shoot and whether the light of the scene is sufficient, so as to take better and more satisfactory photos. We usually choose a large aperture to blur the background, and the large aperture can provide a very bright environment, so the model will be very beautiful.Īdjust frequently according to the light environment: What aperture is used to take a portrait: In fact, it’s OK to turn down the aperture, but the shutter may slow down and need to prepare a tripod for shooting. They can shoot the light of the cross star. Many people don’t know what aperture value to use to shoot the night scene. What aperture is used to shoot the night scene: We can turn down the aperture (such as f9.0 F11, etc.) to shoot again. This is largely because the aperture is too large. When taking group photos with the camera, many people often can’t clearly shoot the people behind. Small aperture is suitable for group photos: Turn the camera to AV and turn the aperture to the maximum. In fact, it is very simple to take such photos. Many people like photos with a hazy background. Photos with great artistic conception can be taken with a large aperture: For example, among Canon lenses, 50 fixed focus lens can have a maximum aperture of 1.2, while the maximum aperture of zoom lens is only 2.8 Some special lenses (fixed focus lens) can provide a relatively large aperture, while the aperture of zoom lens is generally small. Taking portraits, flowers and some small things can make you feel very artistic conception.ĭifferent lenses have different apertures: A large aperture will make the background of the photo very virtual. The size of the aperture has a great impact on the photo. So what is large aperture? Large aperture means that the aperture value is very high (e.g. The size of aperture can control the amount of light entering and the degree of virtualization of photos. There is an index called aperture in SLR camera. What’s the difference between large aperture and small aperture? What parameters are used to shoot some scenes? Let’s have a look. Some of them use more high-end SLR cameras, but many people have used SLR cameras for a long time, but they still don’t know the setting of aperture. Basically, now every family has its own digital camera. Digital camera, which used to be a high-level gadget, has become more and more popular. With the rapid development of economy and science and technology, people’s living standards are gradually improving.
