Hey welcome to a new section in the course this section is all about actually how to shoot video with
your camera.
In this lesson we're talking about exposure basically how to make sure your video is bright enough not
too bright or not too dark with whatever camera you're using.
So we're actually going to head out to a real world location where Sam is going to explain how to properly
expose your video.
So now we're going to talk about exposure and really what this comes down to is how much light is in
your frame and we decide to do this in Phil's kitchen just because a lot of times in documentaries or
you know even shooting something for yourself you want to be in a natural environment.
So it comes to exposure light is really what we're talking about.
It's how much light is on your subject how much light is in your frame.
And there's three ways that you control this with a smartphone you won't necessarily set these but they
will be affecting your image.
And for dislodges or merely cameras it's really essential and that's useful to speed your F-stop or
iris or aperture and your ISO.
So the first is shutter speed.
Back in the day you know for old film camera this would be you take a photo and how quickly did that
shutter expose your piece of film.
Now when it comes to film or video Think of every second the shutter is moving up and down allowing
light in a slower shutter speed allows more light a faster speed allows less light.
So currently I'm at one fiftieth shutter speed so let's go a little bit slower.
Oh man.
We're going way over exposed here.
I get the exposure right so I'm up a one.
Let's go one tenth shutter speed.
Now 6.3 ISO 200.
And you know when the image is still you can't really tell the difference.
But Phil if you could go see that the hand is all blurry you can't really see if you're moving the camera.
It has this weird sort of jittery effect.
It can be really cool and this is actually a lot of people do this at nighttime to get a cool of a ghostly
effect.
Now let's bring the shutter back up and I just want to show that movement again at one fiftieth shutter
and this is really what I consider to be the standard.
So you can see there's still a little bit that blur but it's manageable.
It looks more natural.
Now let's go up to let's go crazy.
Let's go to one for hundredth shudder.
And I think this is where a lot of people go out into the day and they need to expose properly so they
bring the other way up.
So not one four hundredth shutter ISO 200 f 2.8 and you can see this a lot less blur on his hand and
it's a much sharper crisper image.
Some people like this effect you know Saving Private Ryan is a great example of higher shutter stuff.
But it can look a little too sterile a little to digital for me.
So personally I like the issue 150 of next is F-stop.
It's how much light your lenses allowing in.
So on the inside there's an aperture.
It's very similar to your eyes.
You know when there's a lot of light you'll have to close down the aperture making a much smaller hole
if you want to allow more light and you open it up.
So we're at two point eight here.
You can see that the background is slightly out of focus.
Fills nicely in focus and there's depth there so let's close it down.
Now to let's see let's go let's go crazy at the level now which for indoors is kind of crazy.
So we'll bring the ISO up and you can see that a lot more is in focus.
You can see the background image you can see fill in focus.
Everything's kind of in focus so this can be great if you're running and gunning or maybe you're trying
to have everything just look nice and frame and everything in focus.
For me personally I love being as open as possible I think having that shallow depth of field is really
the look I prefer but it's different for everyone.
The final thing and really as I've been adjusting all these things you know the show has remained the
same it's about 150 of where 2.8.
But the iso's of the last last piece of this puzzle really what it used to be is it was the sensitivity
of your film.
It was how how well did it perform in low light versus how unsensitive was it.
You know if you went out into the sunlight and needed something that took more light to expose.
So currently I am ISO 250 which is pretty good.
And you can see now let's go up to 16 hundred.
This is as of 16:00.
It's so much more sensitive to light its way overexposed.
I had to bring my F's up all the way to a to look well expose So all these numbers do coincide with
one another to keep it simple it's how sensitive is your camera.
And at that certain cameras performed better with higher ISOs.
The reason the ace of nest 2 is so popular is that you can shoot at these crazy high ISOs other cameras.
Not so much for a smartphone.
The ISO sensitivity really only takes you so far because it's just a smaller camera smaller sensor all
these other things.
So those are really the essentials for exposure.
And as we go into Solarz and other cameras will get more in depth about how you actually expose your
image and how you use these tools because if you're trying to really get serious about film making While
this can seem daunting and like a lot of information it's something important to learn.
And really it's become second nature after so long.
So we'll get to that later.
And now we're going to be talking about composition.
