hi Tom from phototactic with a quick photography tip guide today we're going to be talking about aperture so what is aperture well aperture simply means a hole or an opening and that's exactly what it is it's a hole or opening in your lens how can a hole in your lens help you with photography volume to tell you okay so it is slightly more than just a hole you take a camera lens like this one you can clearly see inside there's a hole in the middle by using the aperture mechanism on this particular lens I can open hole and make it bigger or smaller so what does this actually achieve well if I open up that hole a lot bigger a lot more light can come into the camera sensor this in turn will allow me to use a much faster shutter speed and I normally would be able to make the hole smaller it restricts the amount of light coming into the camera and then therefore makes the shutter speed a lot slower why would I want a slow shutter speed though well usually I don't only in specific circumstances but this hole performs another function that aperture not only controls the amount of light coming into the camera it also controls the depth of field and the depth of field is the amount in the picture that is in focus and out of focus I'm sure you've all seen portrait pictures where the person's face is really nice and focus and the background is all blurred out this is called depth of field in that particular case we call that a shallow depth of field because only a small amount of the picture is actually in focus to get this effect the hole in the lens must be really big there let's in loads of light so really big hole in the lens gives you a shallow depth of field which gives you that really blurry background look alternatively if I make the hole in the lens really small it restricts him out of life coming into the camera and this therefore gives me a bigger depth of field it makes more in the picture in focus again I'm sure you've all seen landscape pictures where the picture is completely and focused from the very front all the way to the back that photographer has used a narrow aperture or a small hole and it's got all that picture in focus when we talked about a virtue you often hear it referred to as the f-stop or the f-number if i wanted to shoot a portrait I might use an F number of F 2.8 this is a really big hole to get that blurred background look the F part means the focal length and the number after it is actually a mathematical fraction equation which we don't really need to go into today all you need to remember is the larger the F number is the smaller the hole in the lenses and the more depth field you will get so f-22 it's a really small hole but it's a high number and need to get a lot in focus although I wouldn't recommend using f-22 but that's for a different video the smaller the F number is the bigger the hole in the lenses the more light comes in you get a faster shutter speed but you'll get less InFocus so f 1.4 for example would be a really big hold in the lens it would let a lot of light in and give a fast shutter speed but only a very small amount of that picture it would be in focus this can get confusing when talking about large and small numbers and wider and narrower apertures just take them time to get it into your head and narrow aperture means a small hole wide aperture means a big hole a small hole means more InFocus a big hole means less in focus so that's the very basics of aperture as usual in photography changing the aperture changes something else the shutter speed you can watch my other videos on shutter speed in the description box below if you have any questions or comments about this video or anything else please just leave them in the comments and I will try my best to get back to you I hope this short video helped you and I'll see you all next time
