Some simple patterns to make sun twinkles look realistic in your painting.
Hey there everybody, Joe here. I've got
my color app open and that is at
colorapp.org if you want to go to it and
test it yourself.
Joe, as in Joanne, not as in myself, has
sent in this picture and asked the
question, "How can I reflect sunlight
directly off of the waves?" So, we're
not making the reflection of sky or
clouds, but reflecting the sun itself.
So, when water is real sparkly from that
bright reflection. How do we do that?
All right, here's a good way to do it.
We need high contrast. And so, I'm going
to add a layer. I'll just click that
button. It's a clunky app. If you use
it, it's likely to have some errors or
crash. It's still under construction,
but it's enough for me to do a demo
here. So, I'm gonna zoom in and I'm
gonna put white, but I won't put a white
that's brighter than what I think this
photo shows. I don't want to cheat with
digital colors. So, let's take a color
that is, you know, like the pure white
that the picture already has just so
that we're representing this this amount
of exposure. Let me try to get the
brightest one that I've got there. Oh,
we missed that one here. Let's let's go
right here. How about that one? And so
then I'm going to put dots on what I
judge to be the same place on every
wave. So let's really zoom in here. I'm
going to take my line size down.
Now, here's how reflection happens. It's
at the same angle on every wave. So it's
entirely anglebased. Let's do a little
bit bigger line here. Okay. I'm going to
put one here. Now, I chose the dark
color between the reflections. So, I'm
just going to choose that on every spot.
Same place on every wave. Let's undo
that one. It came out kind of crooked.
Put it here. Put it here. Now, since
it's anglebased,
we're going to see one area on the water
that has more
of that specific angle that reflects the
mirror image of the sun. The sun may be
in a much darker part of the sky than
the clouds or other reflections. You
know, the sun is quite a bit brighter
than the sky itself. So, there's there's
not a rule about where to put it. I
don't have to put the bright spot like
on a spot like that where there's
already light reflection or here there's
already reflection. There's no rule that
I have to put the sun in the lighter
reflection. It can be anywhere. So, I'm
putting it here because the contrast
will really stand out. It's strategic.
Putting it on the darker part of the
wave is not something that has to
happen. It's just something I can do to
get higher contrast. And we want
contrast because we don't have the kind
of contrast that our eyes have looking
at the real thing. We've got just shades
of paint in dim lighting compared to the
outdoors. So, I'm just making dots on
relatively the same place on each wave.
And something important is that I'm not
making strange shapes. So, with a
paintbrush, you might dab around
thinking that the shapes can kind of be
scrambled all over. Well, that can
resemble a lot of things other than
reflection. Since we recognize water
really strongly by pattern association,
the the pattern of shapes,
I want to make shapes that are similar
to the sun itself because that's what it
is. It's a mirror reflection of the sun.
So, I'm going to try to stick with round
twinkles. So, if we zoom out now, I've
got those dots on a similar color uh
portion of each ripple, each wave. In
this picture, the ripples are not
distinctly
defined, but that's okay. They don't
have to be. If they are, I'll probably
try to choose a similar part on each
wave rather than putting it on the light
part of one wave, the dark part of
another wave, so that it looks like that
repeating pattern of reflection. Now,
notice I've got a whole bunch of it over
here where the water was already light.
All of this water can have angles that
will show me that mirror image of the
sun. It's not restricted to one spot.
However, if the sun is, for example,
behind my left shoulder, then it's
likely to reflect more over here because
this part of the water with waves that
are facing me have more angles, just a
greater number of surface at the angle
that will show me that sun than what I
might see over here. So, it'll be
everywhere, but think of a gradient
where there's more of it in the spots
that's
uh in in one spot. You know, you pick a
spot and there's more of it in that area
and then less as you go out to other
areas. I'm going to undo whenever I do a
small
uh whenever I do like a crooked shape.
Now, I'm going to try to move a little
bit quicker. Do some just let my finger
skip across like this. This is a touch
screen and I'm just doing little dots.
Trying not to get trying not to get
dotted lines, but when I'm working
faster, it'll be harder. Okay. So,
there's more of it here. Oh, that's a
big spot that came out over there on the
left. Okay. It it kind of dissipates
here. It's just in uh you know, just
just not as frequent. We're getting less
and less fewer and fewer maybe is a
better description. fewer and fewer
angles that are showing me that mirror
image of the sun. And this is very
impressionistic. Like you see, I'm just
just tapering it out. Now, here's what
I'm going to do. I'm going to get my
smear tool. And this could be done with
a brush. It's there's there's a bunch of
ways to accomplish this. But what I want
to do is I'm going to take the amount of
this down right here so that it doesn't
smear it real aggressively. And then
I'll put the size way up. And hopefully
this is going to work. I'm gonna zoom in
and just smear across. No, let's not do
that. Let's take the amount down some
more. Hang on. I want to just barely
smear it because this is a real nice
effect to get the look of like a a lens
flare or a glow. Let's see if this works
works better now. Okay. Still a little
bit aggressive. Let's take the amount
down. Let's do this.
Let's see if this works.
Ah, that's better. Okay, so now we've
got some blurry spots and they're even
kind of stretched out like the shape of
a ripple because it's just a real big
swipe with my blur tool. And now
everywhere I see that blurred
uh everywhere I see that blurred
stroke, that's where I'm going to put my
white dots now. So, let's put some right
where I already have them, like this.
put some in here.
And so this is easy to accomplish with
the paintbrush. You you just do a blurry
spot first, then put a white dot over
it. If you want to do a little twinkle,
you could do that, too. You know, we
could take the uh we could take the size
down on the blurring tool. And whoa,
that's that needs to be way here. I took
the size down on the draw tool, but not
the blur tool. Undo. Okay, let's see if
this works. And then let's put the uh
amount back up.
And we go down. And then we could do a,
you know, do like a X like that. Let's
blend it out this way. Blend it out this
way. You know, you can you can do this
with the brush just as well. I I've done
it a million times when I'm doing little
twinkly stars. So, you know, if this
suits your fancy and you want the
twinkle look, that's possible, too. But
it's not necessary. It's not necessary
for for that effect. Okay. Now, let's go
back. Let's get some white dots put on
here. Let me make sure I've got the
right line size.
There we go. Put some in there. The
little white dot in the middle of the
twinkle. It's kind of a messy twinkle,
but you get the point. Wonder what would
happen if I kind of put this down. And
you know, you want when you do twinkles,
you want consistency of angles. You
don't want to do like a different
different angles on those.
You want them all to have a similar
angle. Sorry, I got kind of obsessed
with the twinkles, didn't I? It was it
was a fun idea and I started running
with it.
Let's put that in
like this. It's fun drawing on other
people's work, too. I got to tell you.
Okay.
These are caused by the shape of the
lens. That's what the twinkles are
caused by if you ever if you ever
wondered. So, they can be different
depending on what camera takes the
photo.
Okay. Now, let's
put our little dots in place. We got
twinkles here, twinkles here, twinkles
here.
Little bigger stroke will help me get it
done faster.
Okay, that's my twinkly area.
Let's get back to what I was doing. I'm
putting them in the middle of gradients.
I can put more than one in a in a little
spot. And it doesn't matter if every
single dot has that gradient uh that
blurry glow around it. It's just a a
cool effect to have in there. Just
something you can do. So, I'm looking
for any little
any little spot that has that
um
blurry
blurry glow effect that I put in there.
Just any of those. Putting dots in
there. Let's Whoops. I didn't mean to
put it on the top of that wave.
Put it here. I see light spots in here.
I'm just touching all my light spots
just a touch. There we go. There's the
effect we're looking for.
Okay, that's it. I'll stop there. You
can see the effect if you really uh take
your time and and uh fill this out with
that pattern. Then yours will look even
better than mine. But this is the
pattern that you can use to achieve
that. So, in the end, the summary is we
want high contrast. So, putting it on a
darker part of the wave may be a good
move. We want non-random shapes, pretty
round, because it's the reflection of
the sun. And we want it on the same part
of each wave that is visible in your
picture. Don't put them on random parts
of the wave throughout. We want it on a
gradient that is more concentrated in
some part of the picture. Doesn't matter
which part you choose, but it's the part
that has the most angles that reflect
it. And then the glow helps. It's a fun
effect to put in there if you want to
put that blurry glow. All right, I hope
that's helpful to you. We'll see you on
the next short video.
