All language subtitles for 86 - HSL Adjustments

In this lecture, we'll explore the tone
curve adjustment panel.

Before we get started, please load
Image Wedding 007

jpg in the develop module.

This photo is great

for this lesson because it has several
different colors contained within it.

This will help us clearly identify
the changes that occur

when we make adjustments to the tone
curve.

Go ahead and expand your tone
curve panel over here.

Also, make sure you click this button
to make sure

you get the full range of options
relevant to the tone curve.

Right now, the tone curve
isn't much of a curve at all.

It's actually a straight line.

Somewhere along this line lies
every color in the color spectrum

that is present in this photo.

The very bottom point of this curve
would represent absolute black.

The very top point of this curve
would represent absolute white.

Watch what happens when I hover my mouse
over different parts of this curve.

You can see that different
segments of the curve are highlighted.

As we move up and down,

the first segment of this curve,
known as Shadows,

represents the darkest range of colors,

including absolute black in anything
close to it.

The second segment represents
the mid range of colors

that fall within the darker
color category.

We then have lights in.

If I go all the way up, I have highlights
which would represent the lightest range

of colors in this image.

The tone curve is typically used to adjust
contrast levels

between different ranges of colors
to demonstrate or increase the contrast

between the lightest in darkest colors.

So first, I want

to put a point at the top of the curve,
and I'm going to drag this curve up.

So watch what happens.

You can see that the latest range of
colors are now getting even lighter.

Now we'll do the same for the darker
range of colors, but this time

I'm going to drag the curve down
to make the darks

even darker.

Okay.

Now let's take a look at the before
and after.

You can clearly see that the lighter
range of colors have become even lighter.

The darks have become even darker,
creating a much higher

degree of contrast
between the color ranges.

Now, if we wanted to, we could also target
the midrange of colors on the curve

by placing our mouse over the middle of
the curve and dragging either up or down.

So you can see the midtown's
getting getting either darker or lighter.

If we move the curve up.

These sliders at the bottom

of the curve allow us to adjust
the breadth of each color range.

If we wanted to widen
the scope of the highlight colors,

we could drag the right
slider towards the left.

We can do the same for the darks by moving
the leftmost slider towards the right.

So you can see that
the darker colors get even darker.

If we do that.

And when we move this right
slider towards the left,

the lighter shades get even lighter.

If you're having trouble
working with the tone curve,

you can always use the four sliders
located here

to adjust your contrast
between lights and darks.

So for example,
if I want to increase the lights

instead of playing around with the curve,
I just drag the light slider

towards the right.

And if I want to make the

dark darker,
I can move the slider towards the left.

So remember it highlights in shadows.

Refer to the lightest
and darkest parts of your image,

whereas lights and darks
refer to your midterms.

We can use the tone curve to target
very specific colors

in our image
using the color select feature over here.

To use this, click on it and hover your
mouse over different parts of your photo.

You'll notice
a point move up and down on your curve,

which identifies where this specific color
lies on the curve.

So right now
I'm hovering over the light orange.

Watch what happens
if I hover over a darker color.

You can see
the point is now lower on the curve.

Once you found the color

you'd like to adjust, click
and hold your left mouse button down.

So I'm just going to adjust
this light red color over here.

So I'm going to hold my left mouse
button down

and I'm going to drag my mouse
either up to make that color even lighter

or I'm going to drag it down
to make that color darker.

Now, you can do this with any color
in the image that you'd like to adjust.

The tone of the tone curve
also has built in presets you can use

if you find the manual adjustments
too difficult to work with.

So for example, next two point curve,
there's a menu so you can select either

medium contrast or strong contrast.

And this way Lightroom

will automatically make adjustments
to your color ranges for you.

We can use the tone
curve to adjust separate RGV channels.

Remember, every color in your color
spectrum is composed

of three primary colors
red, green and blue.

Each one of these colors can be separated
into separate channels.

For adjustment.

To do so, click this button here.

Also, before we continue,
right click on your tone curve

and just go to Flatten
Curve so we can go back to the original.

So this will restore the curve back
to its original shape with no adjustments.

You'll now see a channel selector here,

switch it from RG B to red.

We can now make changes
to only the Reds in this image.

The way this works is
if you bring the tone

curve up,

you add more reds to your image.

If you bring the tone curve down,
you increase

the amount of cyan,
which is actually the opposite of red.

It's quite evident
that when we bring the tone curves down

more, Cyan starts
to appear throughout the image.

Now we can also work
with the green and blue channel.

All we have to do
is switch it from this menu here.

Pulling
the green curve up increases the greens,

whereas pulling it down adds more magenta.

So you're always working with opposite
colors.

And let's go to Blue's

get moving.

The the curve up adds more blues.

And moving it down will add more yellows.

So if you want it to target your lighter

blues, remember you're working
with the top half of the tone curve.

If you want to target your darker blues,

you're working with the bottom
half of the tone curve.

And just like with any other image
we've worked with,

if you want to reset and start over,
just press the reset button and you'll go

right back to your original image
or undo that for just a second.

And if you want to toggle between your
before and after,

you can do so using the toggle switch.

Okay.

So I'll go ahead and reset this image

so we can take it back to its original.

The next panel group we're going to work
with is Hue saturation and luminance.

So please go ahead and click over here
to expand the panel.

And for this exercise, we're going to be
working with image and why 006.

jpg So please go ahead
and bring that up in the develop module.
