Today we're talking about exposure.
-
And specifically, we're going to talk
about how to use your shutter
-
speed on your camera
to get the right exposure for your videos.
-
All the things
we'll talk about in this video
-
apply to any camera you're using,
whether it's DSLR or any other camera
-
that gives you manual control
over your functioning of your camera.
-
This video is going to show you
how to control
-
three basic elements in your camera
to get the right exposure
-
or brightness or darkness,
if that's what you want, for your scene.
-
So in this video specifically,
we're talking about shutter speed.
-
And when it comes to exposure, there's
something known as the exposure triangle.
-
And that's three basic elements
that your camera has
-
shutter speed, aperture and ISO.
-
And I'm going to do three videos,
one video on each of those.
-
And this one is about shutter speed.
-
So when you set your shutter
speed in your camera,
-
there's a general rule
called the 180 degree rule.
-
And that just says whatever
your frame rate is, you double that.
-
And so in this case, we're doing 24
frames a second.
-
So we're using 1/50 of a
second on our shutter speed.
-
And while 1/50 of a second
is not exactly double, it's close enough.
-
And that's as close as
we can get on this DSLR, which is the 60D,
-
so whatever your frame rate is, double
that and put your shutter speed
-
as close as you can
to being double of your frame rate.
-
So on an average shoot,
that's where we would stop.
-
The shutter speed really is
sort of a set it and forget it setting
-
and it can be a little limiting
in DSLR video, but I'm going to show you
-
how to break that rule
as long as you know what you're doing.
-
And by the end of this video, you will.
-
So what that setting is going to do, it's
going to dictate the motion
-
blur in our scene.
-
And the 180 degree
-
rule gives us the motion blur
that you're used to seeing in film.
-
And that's
why it's used here in DSLR video
-
or most pros set up their camera that way.
-
So if you're doing 30 frames a second,
it would be 1/60 of a second.
-
So as you watch these cars
go by in this shot here, notice
-
how in this shot we've cranked
the shutter speed up really high
-
and you can see the cars are going by.
-
It's much more jagged because the shutters
opening and closing much faster.
-
Now, this is a digital camera,
it doesn't actually open and close,
-
but that's what it's simulating.
-
Because it's opening
and closing much faster,
-
you're going to see a lot less motion
blur in the image.
-
So that's what you're seeing in this one
when you crank it up really high.
-
So if you're in a really bright setting
and you're trying to get your exposure
-
by cranking up your shutter speed,
this is what you have to be careful for
-
because it will create this
really jumpy, jagged look.
-
So unless you're going for that, beware.
-
And that's one of the reasons why we leave
shutter speed at a constant.
-
So it always looks the same.
-
My suggestion is that you set it
at the 180 degree rule that's double
-
your frame rate and you leave it there
for your entire shoot.
-
And then you go to your other ways
of adjusting exposure, which again
-
are your aperture and your ISO, which
you'll see in the aperture and ISO video.
-
So check those out.
-
Only after you've gone
through those other settings,
-
if you don't want to change your aperture
and you don't want to change your ISO
-
or you've changed them both to be
-
the maximum that you can get them,
your aperture is as wide as it can be
-
and your ISO is as high as it can go
then you can think about coming back
-
to shutter speed.
-
So if you're shooting something
where there's not a lot of motion,
-
you can get away
-
with decreasing your shutter speed
to get in a little bit more light.
-
So we're at 1/50 of a second here.
-
When I go down to 1/40
or even 1/30 on each of those steps,
-
we get more light into the camera
and that's more real light.
-
It's not enhanced by
the sensor like ISO will be.
-
So if you are in a scene
like we're recording
-
right here where I'm just sitting here
talking to the camera,
-
this is okay,
I can crank down my shutter speed.
-
But you're not
-
seeing much difference in the motion blur
because I'm not doing a lot of moving.
-
However, you're going to want
to probably shoot at that shutter speed
-
for the entire video
so that you have a consistent look.
-
But let's start off
-
by setting our shutter speed per
the 180 degree rule and leaving it.
