In-Depth Information
The following screenshot illustrates its application to smoothen a rendered shadow's
information without blurring the object shape, by routing the
Depth
and
Normal
data
to the determinator:
The Blur node
The Blur node can be used as an alternate and fast solution to defocus an image; the
effect will not be as appealing as the Defocus node though. Using one of the seven
blur modes, this node adds blur to the image, as shown in following screenshot. The
radius of the blur is defined by the
X
and
Y
number buttons. Blur is perceived on the
image when a value higher than the default zero is used. The
Size
input node can
restrict the blur radius as a mask. The values must be mapped between the range of
0-1, as they will be multiplied with the
X
and
Y
number button values.
The
X
and
Y
values signify the number of pixels over which the blur effect can
spread.
The
Bokeh
button will force the blur node to use a circular blur filter. This node gives
a higher quality output, but with higher render times when using the
Bokeh
option.
Enabling
Gamma
does gamma correction on the image before blurring it.
