Hey hey! :) Gleb here. let's talk about gradients
Manu-style... manu-facturing gradients, if you wish.
2
00:00:11,440 --> 00:00:18,400
Gradients... with gradients images become a little
bit nicer in my mind even though there
3
00:00:18,400 --> 00:00:25,120
is nothing wrong with plain surfaces either. in
the previous episode of the Creating Stylized
4
00:00:25,120 --> 00:00:31,840
3d Art course we talked about color, namely
limited color palettes the distribution of
5
00:00:31,840 --> 00:00:40,320
colors in the image, the uninterrupted swatches
of pure colors... pure, but not very pure so to
6
00:00:40,320 --> 00:00:47,520
speak. because a super duper important thing for
the Manu's style as i see it is gradients.
7
00:00:48,960 --> 00:00:56,480
it's a special kind of smoothness that presents
itself everywhere, in the surfaces, in the shaders,
8
00:00:57,040 --> 00:01:03,840
in the reflections, within the chrome surfaces,
because the environment also is a little bit
9
00:01:03,840 --> 00:01:10,800
gradient-ish and obviously in the backdrops.
well, obviously there is nothing wrong with
10
00:01:10,800 --> 00:01:15,520
going absolutely flat and solid in
terms of backdrops and in terms of
11
00:01:16,400 --> 00:01:22,960
colors in your image and many artists excel at
this style. it totally depends on your unique brand
12
00:01:22,960 --> 00:01:30,160
of artistic stylization, but when we try to dissect
and analyze the properties that make the amount
13
00:01:30,160 --> 00:01:38,400
of style what it is, the gradient's strike is one
of the most characteristic, most important things.
14
00:01:39,280 --> 00:01:46,000
i would say it's a general aesthetic perception
of smoothness everywhere in the design, but also
15
00:01:46,000 --> 00:01:54,160
in the visualization. so what makes it so special?
why does it work? let's have a brief look at some
16
00:01:54,160 --> 00:02:02,480
interesting properties of gradients and how you
can exploit it in your art. swoosh... gradients
17
00:02:02,480 --> 00:02:10,000
denote depth. we are used to seeing aerial
perspective as a hint of the distance and depth
18
00:02:10,000 --> 00:02:16,240
and i think that's one of the important properties
of gradients and why they add a little bit of
19
00:02:16,960 --> 00:02:23,360
three-dimensionality to the image. and in addition
to that it looks kind of easy on the eyes because
20
00:02:23,360 --> 00:02:31,520
gradients are everywhere in nature, for example a
relatively flat backdrop like... an open space can be
21
00:02:31,520 --> 00:02:39,680
made a little bit more three-dimensional by adding
some transition between the darker shade of blue
22
00:02:39,680 --> 00:02:46,640
and the lighter shade of blue, it almost gives
a direction to the whole thing and even creates
23
00:02:46,640 --> 00:02:53,280
sort of a vanishing point. the brighter colors
tend to recede into the distance, again, that's
24
00:02:53,280 --> 00:03:01,360
a hint of an aerial perspective, so we kind of make
it a little bit more deep and in addition to that,
25
00:03:01,360 --> 00:03:07,680
gradients is a great compositional tool. let's
say, we can have one strong center of interest
26
00:03:07,680 --> 00:03:14,480
which is a planet in this case, but we can also
like create the second center of interest by
27
00:03:14,480 --> 00:03:20,800
playing with the radial gradient. because our eyes
are naturally drawn to the points of contrast.
28
00:03:21,440 --> 00:03:29,760
and now, voila, this is a symmetrical composition.
nicely done! and once again this effect was
29
00:03:29,760 --> 00:03:35,760
achieved by utilizing the power of the gradients.
let's have a look at one more composition.
30
00:03:36,320 --> 00:03:42,720
so here we have a super emphasized center of
interest, but it could have looked pretty lonely
31
00:03:43,520 --> 00:03:50,080
in the context of the entire frame so by...
by utilizing the gradient that pretty much
32
00:03:50,080 --> 00:03:57,760
goes in this direction from the darker regions of
the image towards the lighter spot in the center
33
00:03:57,760 --> 00:04:03,920
it's inevitable that the eye will be glued to
*this* portion of the image that is the brightest.
34
00:04:04,800 --> 00:04:11,760
um it will go from dark to light like we'll
be drawn to this portion of the image like a
35
00:04:11,760 --> 00:04:17,680
magnet is here or something like that. and on
the contrary the darker edges, the vignette
36
00:04:17,680 --> 00:04:26,080
created by gradient will ward the eye off of
going towards the edges and escaping the image.
37
00:04:26,800 --> 00:04:33,040
so it's kind of a double compositional win if
you think about it. so yeah, gradients are good
38
00:04:33,040 --> 00:04:38,480
for denoting depth and lighting and some
direction, but also as a compositional tool.
39
00:04:40,320 --> 00:04:49,840
okay hello, Manu here! let's look at how the tools
work for gradients. so in Krita let's select the
40
00:04:49,840 --> 00:05:01,040
gradient tool and put color to blue, some kind
of nice blue and for the background color
41
00:05:01,040 --> 00:05:08,960
some kind of red, then let's check that the
gradient is from the foreground to the background
42
00:05:09,600 --> 00:05:16,640
and then just draw a line and you're done. it's
very simple. in tool options you can put it
43
00:05:16,640 --> 00:05:22,960
to radial or linear or all the other choices, by
clicking the small arrow between the colors, you
44
00:05:22,960 --> 00:05:30,400
can switch colors. and in Blender
we can use the gradient node to make gradients
45
00:05:31,040 --> 00:05:38,880
in this example for the world you can see the
node setup in here. it's quite simple to make.
46
00:05:39,760 --> 00:05:47,920
and look at how you know how nice sunset we have
we have. also those different options for gradients
47
00:05:48,560 --> 00:05:57,360
just like in Krita, but linear works best for
the world setting by adjusting the sliders you
48
00:05:57,360 --> 00:06:03,280
can change the colors easily and with plus
and minus you can remove them or add them
49
00:06:04,400 --> 00:06:11,360
also by holding down ctrl and clicking on
the color strip you can add those markers
50
00:06:12,400 --> 00:06:19,840
and so here we have a nice nice gradient
background which reflects from the car.
51
00:06:20,720 --> 00:06:29,200
cool! :) when you make a gradient it might make sense
to add a little bit of other colors than just
52
00:06:29,200 --> 00:06:35,600
two and then blur everything. i think it
makes a gradient more fresh
53
00:06:35,600 --> 00:06:43,040
in a way. then you can also add gray noise on
top of it. you probably cannot see this image,
54
00:06:43,040 --> 00:06:49,600
because of the video compression,
so here it is with 10 times zoom.
55
00:06:50,640 --> 00:06:58,720
so when you have this grey pixelated noise image
on top of your gradient and in overlay or multiply
56
00:06:59,440 --> 00:07:07,360
blending mode, then you get rid of the banding
which is very annoying. it helps that Photoshop
57
00:07:07,360 --> 00:07:16,400
and Gimp has this dither option for gradients.
so that's about it for the gradients. short and sweet.
58
00:07:17,360 --> 00:07:23,600
yay! and what is also important, gradients
and soft lights are friends, our biggest
59
00:07:23,600 --> 00:07:30,960
friends in the universe ;) because gradients not only
denote some kind of lighting, they are created by
60
00:07:30,960 --> 00:07:37,040
the soft lighting. you can have just a few
objects in the scene like we have here,
61
00:07:37,920 --> 00:07:41,680
it's the Manu's scene obviously and then bam!
62
00:07:42,480 --> 00:07:50,480
one light source which is relatively big and thus
relatively soft, it creates a bunch of gradients
63
00:07:50,480 --> 00:07:57,040
all over the place. the bounced lighting
specifically, but also like the general diffuse
64
00:07:57,040 --> 00:08:03,760
lighting and reflections, all of these things
contribute to drawing a bunch of gradients
65
00:08:04,560 --> 00:08:10,400
across the image, across the surfaces, especially
considering the fact that the surfaces themselves
66
00:08:10,400 --> 00:08:17,600
are curved, so we have... the highlight and
the shadow and the transition between them
67
00:08:18,400 --> 00:08:25,040
and this transition is the softer the bigger is
the light source. well, without denoising it's a bit
68
00:08:25,040 --> 00:08:31,920
problematic to see it in its full glory, but with
the viewport denoising, which is Optix in my case
69
00:08:31,920 --> 00:08:40,240
here but it can be Intel open image denoiser, it's
much more soft and smooth. so by using the softer
70
00:08:40,240 --> 00:08:45,280
light sources, which are basically the bigger
light sources in relationship to the objects
71
00:08:45,840 --> 00:08:54,320
we can create a huge variety of gradient effects.
that partially brings us back to the point that
72
00:08:54,320 --> 00:09:00,240
the realistic rendering is a part of this
kind of style, because without the bounced
73
00:09:00,240 --> 00:09:05,440
lighting and without the physically correct
reflections we wouldn't have had gradients,
74
00:09:06,000 --> 00:09:12,720
which is somewhat ironic. all right awesome! thanks
for watching, i'd like to mention once again
75
00:09:12,720 --> 00:09:16,720
that let all the flowers bloom, there
are different kinds of stylization,
76
00:09:17,280 --> 00:09:22,960
solid colors, flat colors can look awesome
like in this game acid by Nicolas Buchot
77
00:09:23,520 --> 00:09:29,760
or you can go pretty solid and flat, but spice it
up with the use of gradients just a little bit,
78
00:09:30,800 --> 00:09:37,360
like in this image by Scott Zenteno, an amazing
concept art. and there are different kinds of
79
00:09:37,360 --> 00:09:45,440
things like... well, pixel art, that has quantized
transitions between one color and the other
80
00:09:45,440 --> 00:09:52,400
but still some gradients are readable arguably,
and still it looks fantastic! kudos to Valerii Kim.
81
00:09:53,760 --> 00:09:57,760
thanks for watching! my name is
