hi this is Marty from Blue Lightning TV
I'm going to show you an effective
technique for retouching skin that
retains the skin's texture while it
removes skin blotches and imperfections
this technique is called frequency

thanks open a photo of a face that you'd
like to retouch I downloaded this one
from Shutterstock the first step is to
make two copies of the photo by pressing
ctrl or command J twice
name the top layer high-frequency
and the middle layer low-frequency blur
click off the eyeball icon next to the
top layer to temporarily hide it and go
to filter blur and Gaussian blur drag
the slider until it blurs the skin just
enough to hide most of the pores and
blotchiness then click OK
make the top layer visible and active
go to image and apply image
for the source layer click low-frequency
blur and for the target blending mode
the scale is 2 and offset is 128 then
change the blend mode to linear light
at this point your photo will look
exactly the same make the middle layer
zoom into areas of the face by pressing
Z to open your zoom tool and drag it
over the forum
open your lasso tool
over the inside of the forum will
feather it so its edges will be soft for
me the best way to preview the amount of
feathering is to click the refine edge
button or go to select and refine edge
drag the feather slider to the right
until the inside of the selection is
blurred approximately this much the
actual pixel amount on yours may be very
different than mine depending on your
photo size and resolution
remember your pixel amount and click
at the top
feather field type in that amount
deselect it by pressing ctrl or command
D to apply the feathering draw another
selection inside the forage
and go to filter blur and Gaussian blur
slide the blur radius to an a map that
makes the blotchiness disappear the
texture remains because it's on a
different layer click OK and deselect it
if you see some imperfections in the
texture we'll take care of them in a few
minutes right now we're just concerned
with removing the blotchiness and
overall inconsistencies to reposition
the face on your canvas press and hold
the space bar as you drag the image
draw another selection around the cheek
and make sure you don't get too close to
the eyes hair lips and neck press ctrl
or command F to repeat the last filter
you used which was Gaussian blur then
delete the selection draw another
selection around the other cheek repeat
the filter and deselect it I'll repeat
these steps for the chin
next let's retouch the nose
since the nose has more problems with
texture than with blotchiness where we
touch its texture to do this make the
high-frequency texture layer active and
this time we'll use the clone stamp tool
make sure the mode is normal
the flow is a hundred percent and the
current layer is showing make its
opacity approximately 35 to 40 percent
to make your stamp tool bigger or
smaller press the right or left bracket
key on your keyboard will copy the
texture of a smooth area of the skin and
clone it onto the nose to do this
alt-click or option-click on a smooth
area of the skin to copy its texture and
brush over a small area of the nose to
clone the texture onto it go back to the
same smooth area or click or option
click on it and brush over another small
area of the nose continue this until the
entire nose is smooth remember we're not
cloning color nor brightness and
contrast or only cloning texture
let's retouch the neck of your subject
drag the neck into view
since the neck has problems mostly with
skin blotchiness I'll make the
low-frequency blur layer active
and open my lasso tool again I'll draw
inside the neck and shoulder blades
avoiding getting too close to her
clothing chin and hair I'll repeat my
last filter which was Gaussian blur and
I'll deselect it to fit your image back
onto your canvas press ctrl or command 0
to see the before and after alt-click or
option-click on the eyeball icon next to
the bottom layer to hide all the other
to make all the other layers visible
again alt-click or option-click on the
eyeball icon again
if you want to finesse it more by
removing tiny spots of texture
imperfections zoom into the area you
want to finesse by pressing ctrl or
command + the plus key on your keyboard
and drag your subject to the area you
want to finesse make your high-frequency
texture layer active again this time
we'll open the Spot Healing Brush
brush a bit larger than the spot you
want to remove and simply click or brush
over the spot continue to click or brush
over other tiny texture imperfections
until the entire face is flawless this

Hi. This is Marty from Blue Lightning TV.
I'm going to show you how an effective technique
for retouching skin that retains the skin’s
texture, while it removes skin blotches and
imperfections. This technique is called, "Frequency Separation".
Before we begin, if you enjoy my tutorials,
show your support by becoming a patron to Blue Lightning TV.
Go to patreon.com/bluelightningtv
(all one word) or simply click the link in
this video's description, which is below the
title of this video. Thanks!
Open a photo of a face that you'd like to retouch. I downloaded this one from Shutterstock. The first step
is to make 2 copies of the photo by pressing
Ctrl or Cmd + J twice.
Name the top layer, "High Frequency_Texture"
and the middle layer, "Low Frequency_Blur".
Click off the eyeball icon next to the top layer to temporarily hide it
and go to Filter, Blur and Gaussian Blur.
Drag the slider until it blurs the skin
just enough to hide most of the pores and
blotchiness. Then, click OK.
Make the top layer visible and active.
Go to Image and "Apply Image".
For the Source layer, click
"Low Frequency_Blur" and for the Target Blending
Mode, click "Subtract". The Scale is 2 and
Offset is 128. Then, click OK.
Change the Blend Mode to "Linear Light". At this point,
your photo will look exactly the same.
Make the middle layer active. Zoom into areas of
the face by pressing "z" to open your Zoom
Tool and drag it over the forehead.
Open your Lasso Tool and draw a selection over the inside of the forehead.
We'll feather it, so its
edges will be soft. For me, the best way to
preview the amount of feathering is to click
the Refine Edge button or go to Select and Refine Edge.
Drag the Feather slider to the
right until it's blurred approximately this much.
The actual pixel amount on yours, may be very
different than mine depending on your photo's
size and resolution. Remember your pixel amount
and click "Cancel".
At the top, in the Feather field, type in that amount.
Deselect it by
pressing Ctrl or Cmd + D. To apply the feathering,
draw another selection inside the forehead.and go to Filter, Blur and Gaussian Blur.
Slide the Blur Radius to an amount that makes the
blotchiness disappear. The texture remains
because it's on a different layer. Click OK
and deselect it. If you see some imperfections
in the texture, we'll take care of them in
a few minutes. Right now, we're just concerned
with removing the blotchiness and overall
inconsistencies. To reposition the face on
your canvas, press and hold the Space bar
as you drag the image.
Draw another selection around the cheek
and make sure you don't get
too close to the eyes, hair, lips and neck.
Press Ctrl or Cmd + F to repeat the last filter
you used, which was Gaussian Blur.
Delete the selection and draw another selection around
the other cheek. Repeat the filter and deselect
it. I’ll repeat these steps for the chin.
Next, let's retouch the nose.
Since the nose has more problems with texture than blotchiness, we'll retouch its texture. To do this, make
the High Frequency texture layer active and
this time, we'll use the Clone Stamp Tool.
Make sure the Mode is Normal, the Flow is
100% and "Current Layer" is showing.
Make its Opacity approximately 35 to 40%. To make
your stamp tool bigger or smaller, press the
right or left bracket key on your keyboard.
We'll copy the texture of a smooth area of
the skin and clone it onto the nose. To do
this, Alt-click or Option-click on a smooth
area of skin to copy its texture and brush
over a small area of the nose to clone the
texture onto it. Go back to the same smooth
area, Alt-click or Option click on it
and brush over another small area of
the nose. Continue this until the entire nose
is smooth. Remember, we're not cloning color,
nor brightness & contrast; we're only cloning texture.
Let's retouch the neck of your subject.
Drag the neck into view. Since the neck has
problems mostly with skin blotchiness, I'll
make the Low Frequency Blur layer active
and open my Lasso Tool again. I'll draw inside
the neck and shoulder blades avoiding getting
too close to her clothing, chin and hair.
I'll repeat my last filter, which was Gaussian
Blur, and I'll deselect it. To fit your image
back onto your canvas, press Ctrl or Cmd + 0.
To see the before and after, Alt-click
or Option-click on the eyeball icon next to
the bottom layer to hide all the other layers.
To make all the other layers visible again,
Alt-click or Option on the eyeball icon again.
If you want to finesse it more by removing
tiny spots of texture imperfections, zoom
into the area you want to finesse by pressing
Ctrl or Cmd plus the “Plus” key on your
keyboard and drag your subject to the area
you want to finesse. Make your High Frequency
texture layer active again. This time, we'll
open the "Spot Healing Brush". Make your
brush a bit larger than the spot your want
to remove and simply click or brush over the
spot. Continue to click or brush over other
tiny, texture imperfections until the entire
face is flawless.
