The Photography Tutorials For Beginners series continues with a tutorial on Aperture. In this video, you will learn what aperture is, what it means to have a slow or fast, large or small aperture, the trade-offs and how to get started practicing manual aperture control.

Hey, this is Scott, one kid with a storyteller, with a camera talking about all the things photographers like you and I are thinking about. In this video we’re going to be talking about the aperture which is inside of your lens and it opens and closes to let more or less light through the lens to your camera. Your aperture is inside of your lens. It is well on an ICAD lens. I can easily just do this and you can see it. No, this, this lens in particular is a 20 millimeter 1.8 lens. There really is no limit to how how small or large an aperture could really be, what lens you buy. It actually does make a difference if this lens can go as fast as 1.8 and by as fast, I mean the aperture number is actually small, so the smaller the number, the faster the lens is as far as in low light.
So at 1.8 it is actually going to let a ton of light through and as you close up the aperture to something, this lens goes all the way to F 16 as you close up the aperture to F 16 it means that it’s going to let less light through that lens because the hole is going to be much, much smaller. 1.8 that hole is going to be quite large. Now there’s a downside when it comes to aperture because for one thing, if you go to the smallest aperture that you have on this lens, it’s 1.8 and you go to that or you go to the largest aperture, which on this lens is [inaudible]. You will not get the sharpest image that you would get with this lens. There is something called a lens sweet spot. If you want to learn more about the lens sweet spot, just click that card right up there and I’ve got a whole video on what the lens sweet spot is and how to find your lens sweet spot.
With everything in photography, there’s a trade off. You learn about the tradeoffs in the shutter speed video, click the card right there in order to view the shutter speed video, there is something else with the aperture as well, besides from your limitations and besides from your sweet spot. There’s one of the thing that’s very important when it comes to aperture and that is if you go to 1.8 on this lens, that means that your subject will be in focus and the background will be very blurry. You’ll have a very shallow depth of field, but at the same time the focus will be so pinch sharp at 1.8 on whatever you’re focusing on that if you’re photographing a person at 1.8 most likely your eyeball, the eyeball will be in focus, but the nose, the chin, the mouth, the ears will all be out of focus.
That’s how, how how shallow the depth of field can be with a lens like this at something like 2.8 3.5 or 4.0 at that aperture, you’re more likely to have more in focus at 5.6 or at F eight you’ll have even more in focus, but then the background will not be as blurred as you might want. So that is a, that is a trade off that you have to think about is how your subject will be in focus as related to your background in focus as you vary your apertures. Now when I’m photographing people, I’m typically around four. When I’m photographing landscapes, I’m typically, or buildings, I’m typically at F eight or F 11 of course, this all depends on the lens as well. That’s why I say to check out the lens sweet spot. Figure out how your lens and your camera interacted with each other at different apertures.
Now of course as you open and close the aperture, it impacts what you have to do with your shutter speed. So to get a feel for where your aperture is gonna do for you. Set your camera to aperture priority. Give it a try. Learn that way before you dive into full manual mode. Learn operator by putting your camera in aperture aperture priority. Let your camera choose the shutter speed. Let your camera choose the ISO by putting your ISO in auto ISO as well. I don’t suggest putting your camera fully into manual until you get a full deep understanding about how everything works that you will be controlling in manual mood. In the next video, I’m going to be diving in to ISO, so stay tuned for that. Click the subscribe button below. Right now. I publish new videos every Monday and Thursday whenever possible.
