- A lot of my students will ask me,
"What exactly is the difference between texture,
and dehaze, and clarity
when it comes to these specific sliders?"
They're all together in that detail section.
Let me take a minute to explain the differences in the math
behind those three sliders.
So we've got a few different sliders here
in presence section.
So texture, and clarity, and dehaze,
what is the difference?
I'm going to start with the oldest one first.
Clarity is going to look at your 50% gray,
and that's going to be the area in here of your histogram
and it's going to try and create contrast
within the 50% gray area of your image.
So actually, keep an eyeball on the histogram
as I pull my clarity all the way up.
You can see that the histogram actually is changing,
because it's trying to create contrast
in those mid tones of the image.
So I'm going to double click the word clarity right here,
which will bring it back to baseline.
Now, texture's a little bit different.
As I polarize my texture from top to bottom,
from 100% to negative 100,
you don't see as big of a change in the histogram
as you do with clarity.
And that's because what texture's going to do
is it's going to try and look for like colors
and it's going to try and create texture
within those like colors.
So that's how texture works.
Clarity, I already explained.
Dehaze has to do with atmosphere.
So when things get further away,
they lose contrast and they also lose warmth.
So they get cooler and they get less contrasty,
and the black point tends to really fade very quickly.
And so dehaze is actually going to fix all three
of those problems in one slider.
So obviously I rarely use it on skin for any reason.
The only reason I've ever used dehaze on a face
is to slightly, just by decreasing it a little bit,
getting rid of like five o'clock stubble from a man's face.
That's the only reason
that I've ever used dehaze on a face.
So that's the difference between the three,
texture, clarity, and dehaze.
