CAMERA BASICS – Aperture, Shutter Speed, and ISO

CAMERA BASICS – Aperture, Shutter Speed, and ISO


what’s going on guys today I want to
give you a quick overview on aperture shutter speed and ISO you aperture shutter and ISO these are the
big three when it comes to photography and they can be a little bit tricky to
understand it first so hopefully I can help you understand the relationship
which will make things a lot simpler for you Daniel Peter over at photo blog
Hamburg put together this cheat sheet on the big three and it’ll hopefully give
you a visual as I discussed today so let’s break this down we’re gonna go
through each one by one and we’re gonna go over the two main functions of each
now each of the three controls exposure but on top of that each of the three
also has an artistic control so let’s start with aperture aperture is the
measure of how open or closed the iris of your lenses and it’s measured in the
term called f-stop the larger your f-stop number the more closed down your
irises which means it lets in less light and thus the exposures darker this
smaller your f-stop number the larger the opening of your iris meaning it’s
letting in more light meaning you have a brighter exposure now there is an
artistic use of aperture as well and that’s depth of field when you have a
low f-stop number meaning you’re letting in a lot of light in your exposures
brighter you’re gonna have a shallower depth of field this is how you’re gonna
have nice cinematic look in your photos and in your videos when you have a
higher aperture or f-stop number you’re gonna have a much larger depth of field
this is great when you’re shooting some sort of landscape or environment where
you want everything in focus second we’ve got shutter now the shutter is the
measure of how long the shutter of your camera is open and thus allowing light
to hit your camera sensor so when we’ve got a fast shutter one over two
thousandth of a second for example it means that you’re gonna be letting in
less light you’re only letting in light for one mm of a second which means it’s
gonna be a darker exposure than a longer shutter speed because you’re only
letting in that brief amount of light if we have a longer exposure say 15 seconds
that means your shutters open for 15 whole seconds and letting in light for
that amount of time which means it’s gonna be
a much brighter exposure now that’s the exposure level of shutter but what’s the
artistic use well the artistic use is motion blur when you have a very fast
shutter you’re essentially freezing time you could be taking an action photo or
some sort of sport photo with a high shutter and it’s freezing that action
you won’t see any blur it’s as though everything is just stopping however if
you have a long exposure you’re gonna start to have blur in your shots because
the shutter is open wide and every motion that’s happening for the entirety
of that shutter being open is getting captured by the sensor with long shutter
speeds this is how you’re gonna get those night trail or sorry the light
trail photographs or you’re gonna get photos of the stars it’s when you’re
doing these very long exposures that you can do these sort of tricks but for
these you want to make sure that your cameras on a tripod because any motion
in the camera is gonna be picked up by the sensor and finally we have ISO ISO
measures the sensitivity or the post image grain in your sensor so what this
means when you have a high ISO it means that your camera sensor is more
sensitive to light so it’s gonna be a brighter exposure however it’s also more
sensitive to grain so your image actually breaks down a little and gets
somewhat grainy and noisy whereas if you have a low ISO somewhere around 100
you’re gonna have a lot less sensitivity which means that your exposure is darker
but your image is a lot crisper and less grainy this is something to think about
when you’re in dark place and you’ve already adjusted your shutter and
aperture and you need to play with your ISO if you push the limits too high then
you’re gonna run into some grain issues when you’re looking back at your footage
or your photos based on the artistic look that you’re going for it you can
combine any of these three when you want to get your exposure to the right level
and you want to adjust your depth of field your motion blur and make sure
that your camera sensitivities at the proper levels these are the three that
you need to use and you can sort of get a sense of how their relationship works
we’ll get into a more detailed description of how each of these work in
future videos but for now I hope you have a better understanding of the big
three and how they relate thanks for checking it out guys go ahead and like

  1. Thanks for such a well constructed tutorial. A special thanks for the visual comparison tables. Those really help put everything in "perspective." No pun intended.

  2. Hi there! I'm confused, I know that the larger the F stop in aperture (f22) is the smallest aperture while smallest the F stop (f2.5) is the larger aperture. F22 should be darker while F2.5 should be brighter. But why is it that if I use f22 in aperture mode w/out flash, the photo is brighter and the f2.5 is darker. Please enlighten me. Thanks!

  3. Thanks a lot for making this video, I was taking notes when watching it. I had issues when shooting videos outside, because of the confusion of these 3 points, sometimes the video wasn't satisfied as what I wanted if I shot in darker place. But this video gave me a basic concepts. Thanks a lot^^

  4. Thanks so much for this! this is probably the first video I've come across (& i've watched a lot) that really explained this clearly and put it in a way that was easy to understand for someone who isn't a seasoned photographer!

  5. wow this is the best anyone has explained it so far, i totally understand it now! good use of visuals to help!!!! thank you!

  6. Thanks for explaining so concisely, to a noob like me. Can't wait to try out settings on my point and shoot before I make a jump to higher quality optics.

  7. So simple and effective tips. Thanks for using examples along with your explanation. When it comes to tips on photos, it's better to show then just tell. Subscribed.

  8. This is actually the only video on youtube that explained everything in like 5 minutes, even less.
    Went from amateur to pro😂

  9. GREAT tutorial man. Clear & quick. One of the best i've seen on this basic topic. Which are the most important!

  10. Thank you for this amazing video. For once a simple a brilliant explanation with examples. You have just helped me in so many ways! Thank you!

  11. So… what about exposure control (the physical or digital dial)? I get what it does, but how does it compare to ISO, etc? Thanks in advance!

  12. First time I used a film SLR I left the shutter speed too low and everything was blurry and long exposed. Some looked really good other bunk.

  13. Very educational yet simple. I always have issues confusing with the numbers. Like f stop #, shutter speed ratio, iso #. Its really a great help

  14. a had a pretty good understanding of what these things where, but watching this video made everything click!

  15. I'm a professional photographer and I've honestly never heard of anyone have a better explanation of the basics of photography. I know you have a real job but you would be an amazing teacher!

  16. Thank you! This was a super helpful video, I've been struggling to really remember these facts, this breaks it down so well!

  17. This video right here explain everything about aperture, shutter and iso in under 14min and was pretty straightforward too. Thank you jus going straight to point lol

  18. Fantastic video. English is my second language, and sometimes I struggle with understanding youtube videos, but the way you explained it makes it so clear and easy. Thank you so much!

  19. This was a perfect description, I’m actually surprised as to how easy it is to understand now LMAOOO I was freaking out before

  20. This is my first video of photography and I clearly understand your explanation. You are a teacher. I will be watching more of youe videos for a beginner like me. 😊😊 God bless you!

  21. Among all the beginner photography videos I've ever watched, this is the easiest one to understand. Other videos just confused me, but this cleared up all of my confusion on how to use these three. Thank you so much for this!
