Now the third tool that you have
for your exposure is your ISO.
This tool, just like the other ones,
has kind of a dual functionality.
So it's going to help change
how bright or how dark your images,
but it's also going to control how clean your images.
And so when you're using your ISO,
it's gonna be a number like one hundred,
two hundred, four hundred, eight hundred.
It basically doubles every time you add a stop of light.
But it's how sensitive your sensor is too light.
At the lower numbers,
your image is going to be darker.
And at the higher numbers,
your image is going to be brighter.
If you're shooting at something like an ISO 100,
it's gonna be a very dark image.
Whereas if you're shooting at ISO 3200,
your image is going to be much brighter.
Now typically, your image is
going to look good when you're shooting at
lower numbers because your camera has
a base ISO and the base ISO is basically the ISO.
Your camera looks the best,
so there's no noise in your footage.
Now if you start shooting at higher ISOs From that,
you're going to start introducing
more noise and your footage
is not going to look as clean.
And so if you're shooting at
night and you need more exposure,
well, you can bump up your ISO,
but the issue is depending
on which camera you're working with,
that might introduce a lot of noise and grain
into your footage and it's not going to look as good.
So ideally when you're using your ISO,
the rule thumb is lower ISO numbers
is gonna be a cleaner image.
Now there are some cameras that are coming
out dual native ISO.
So for example, my Sony camera,
it has to ISO's where the image is going to look.
The most clean, one is lower and one is
higher for when you're shooting
these nighttime style shots.
So depending on the camera that you have,
you just wanted to know what your base ISO is.
And those numbers are going to be
where the image is going to look the cleanest.
Now, your base ISO might be 400,
but you could shoot at 200 or
100 and the footage is still going to look good.
It's more when you're moving up into the higher numbers,
is when you're going to start introducing
this noise and you're going to have you
having these problems.
So the rule of thumb when it comes to
ISO is shoot at the base ISO
or shoot a little bit lower if you
need a little bit darker footage.
