What is ISO? - Video Production Training

In this video and be telling you
everything you need to know about.

ISO. What it is, what it ain't,
and why it's so important.

It's coming up.

Hey, everyone.

Steve here from learn online video.

And today we're talking ISO.

This is going to be a crash course in ISO, so
if you're new to camera operation.

By the time you finish this video,
you will have a really good

understanding of what ISO is.

So what is is so well, in a nutshell,

it is your camera's sensitivity to light.

The higher the ISO, the more light
you let into your camera.

The lower the ISO, the less light
you let into your camera.

The higher the ISO, the brighter
the image, the lower the ISO, the darker the image.

So if you're shooting some very bright
light outside on a sunny day,

then you won't need to let as much light
into your camera.

So choose a lower ISO.

But if you're shooting somewhere
dark, like inside or outside at night,

then you will need to let more light
into your camera.

So choose a higher ISO.

Now, as a general rule, you want to keep
your ISO as low as possible.

And this is really, really important
because the higher the ISO,

the more grain you will add to your image
or digital noise

or in layman's terms,
the worse your image will look.

Here are some video shot at one.

It's a nice, clean, crisp.

And here is some video shot at 5000 ISO

horrible, grainy and awful.

Not the look we're going for.

Now, these two videos were opposite
ends of the scale,

but hopefully that will give you a good
understanding of how increasing your

ISO too much
can affect the quality of your image.

So in an ideal world, you will only ever
shoot at 100 or 200 ISO.

This will guarantee a nice, clean,
crisp image,

but it won't always be possible
due to lack of light.

Now, in order

to be able to control your air
so you will need to shoot in manual mode.

If you're shooting in auto mode,
then your camera will decide the ISO for

you, which, if you're just starting out,
may not be such a bad idea.

But I strongly encourage you
to start shooting in manual mode.

You want to be in control of your camera,
not the other way around.

So we're really just scratching
the surface of video fundamentals here.
