DIFFUSION 7DIFFUSION SLIDER COLOR TEST
Now let’s take a look at the example below,
which is our first visual experiment. Here,
you’ll find two segments in this image:
each section has five rainbowcolored lines
stacked on top of one another, and then
at the bottom, each section has one set of
colored dots. This experiment is using the
Healing Brush tool. On the left, I used a
Diffusion slider value of 1, and on the right,
a Diffusion slider value of 7. Which side
do you think does a better job of trying to
blend the surrounding grey color in with the
colors? I think it’s the left side.
SKIN TEST
Now, what exactly does this mean for you portrait and beauty retouchers out
there? Let’s look at this next experiment. Here, you’ll see a grid of an image
by Michael Corsentino. (Before anyone complains about why I’d remove a
beauty mark from a model, this is purely for explanation sake. I would never
remove a mark like this during a regular retouch, but it’s a perfect example to
show you how the Diffusion slider works on skin texture.)
First, I tested the Diffusion slider values for the Healing Brush tool,
and then, the Spot Healing Brush tool. When we use a tool to remove
a blemish, we not only want it to erase the blemish, but also blend in
the new skin color and texture with the surrounding areas, so it looks
like there was nothing there in the first place. So, for both these tools,
a Diffusion slider value of 1 gives a much better result when it comes to
skin retouching.Take a moment to pay particular atten
tion to the colored dots on the right side
(the Diffusion 7 side). When I tried to blend
them into one another using the Healing
Brush tool, it gave me exceptionally strange
results. If you look closely, you can see a
diagonal, accordion shapedlike line I drew
between the colors. How in the world did
Photoshop think to add blue in between
me trying to heal between red and yellow?
And again, and even more apparent, when
I healed in between yellow and green, the
tool decided to throw some purple in there!
If you look at the same dots on the left side
(Diffusion 1), you can see that there have
been no contaminating colors added into
the healed sections by the tool. (Look for
red arrows; there aren’t any.)
