Hello and welcome to my new video! In this clip I want to talk about the aperture. What is it? Why do I need it? and what setting can I set on my camera to optimize the image quality or a certain focus point? Let’s go! Before we start a little remark in my own interest: Share this video! If you enjoy watching it, then please like it and don’t forget to subscribe to my channel for more exciting content on the subjects of vlogs, photography and filming But now we’re starting for real! What is the aperture? It is an opening in the camera’s lens with which I can regulate how much light will hit the sensor. Which means I’ve got a little hole that is surrounded by slats/lamellae depending on the type there are more or less slats which are meshing to open or to close Which means, if the slats are long, the aperture opening is small are the slats short, the aperture opening is big. You can adjust that setting on your camera by choosing a aperture value (f-number) Is the f-number small, the slats are short and the aperture opening is big. A lot of light can get into the camera, because the opening is big Is the f-number big, the slats are long and the aperture opening is small so only little light can reach the camera’s inside. If I use a very small f-number, almost no additional light can reach the sensor. If you squint a little, you can still see everything it just gets darker and your focus point changes so if I squint, less light gets into my eyes and everything I see appears a little darker But if I go outside and it is dark, I will open my eyes and also my pupils will dilate to let more light into the eyes Think about cats or just your own eyes If there’s not as much light, the pupil dilate to capture more light is it too bright, you’re going to squint and also your pupils will get smaller Easy to test with a flashlight, some of you might know that from the doctors If I want more light, I have to open the aperture, meaning open up the aperture opening Is there enough light already and I don’t want the results to be overexposed but regulate it over my settings I will choose a bigger f-number and close the aperture opening. When do I use what? As we already know we can do two things via the aperture #1 we can regulate the light and #2 at the same time regulate the focus point About the “what am I using it for or when?” For example, if the light is extremely bright as I said before, I would start regulating my aperture because maybe I cannot turn down the ISO any more and sometimes I just don’t want to change the shutter speed so the easiest way is to regulate it over the aperture If I don’t have enough light, I can turn up the ISO value, but through that the results will be more noisy or I can change my shutter speed, but then I might need a tripod. If I reduce the shutter speed, then I don’t have to open my aperture That would be the time (or bulb) exposure meaning I leave the shutter open for a longer time and over a longer period of time, light will hit the sensor and through that I can regulate the light that will affect the results There are a couple of side-effects though So first we’re trying to find out what it is, we want to regulate through the aperture The first thing I check is, what I actually want, do I want to take portrait shots and I only want the face to be in focus and the shoulders blurred then I will choose the aperture small enough, that the eyes or the face are in focus and the rest is blurred We call that depth-of-field So the aperture regulates the light, but also the depth-of-field Because the bigger the aperture, the more light gets in and like I said the visible area stays the same If I open the aperture even more, more additional light will get in and through that the edges get more blurred and the bigger the opening is, the more the blurred part increases, the more light gets in and you could say the blurriness moves to the center If I want a big area to be in focus, like a group photo or architecture, houses or landscapes Then I don’t want a small area to be in focus and everything else is blurry I want it all to be in focus, so I have to choose a very big f-number without losing too much of the light you have to play around a little with the settings or additional lights with a flash or natural lights In any case the aperture opening has to be very small and through that there won’t be a lot of additional light, I say additional light because it seems to reflect best what I want to say Less additional light gets in, so the edges will be in focus as well Now we know, with the aperture we can regulate the light meaning I can get more light if there’s not enough just like opening my eyes to dilate my pupils I can get more additional light, but I can also reduce the light, if is too bright already so it won’t be too blurry Sometimes you just have to check on the situation you’re in if I have to be fast, I usually use a higher f-number not like 1.4, 1.2, 1.8 which is very low, but I use something like 2.8 or even 4 depending on the lens you’re using and I’m on the safe side, I still have enough depth-of-field (depending on the lens) but I can be sure that it won’t be too blurry, if I take pictures against the light could be artsy maybe Summarizing: The aperture can be closed and opened you can adjust that a small f-number means a big aperture opening a big f-number means a small aperture opening You can remember that through the slats which close the aperture opening if the slats are long, the f-number is big and the opening is small are the slats short, the opening is big and the f-number is small I can regulate the light and it results in two things #1 the exposure of my result, if it’s a video or a photograph #2 the depth-of-field meaning also the focus area not the “where” the focus is exactly, but “what” is going to be in focus is it just a small area, or little more or everything and the rest blurry That’s what I do with the aperture I hope you liked my video, if so please leave a like don’t forget to subscribe and see you next time!
