Changing the saturation with the Selective
Saturation effect
Under the
Style
tab, we have another effect that initially may not look useful at all.
Selective Saturation
is one effect that when applied will create an oversaturated
image that doesn't look natural. So, how can we use this effect?
One application is using this effect to actually remove saturation from the scene.
This may happen because of the previous effects we used and this effect can be used
as the final way to bring a more natural look to the image. For this, you need to bring
the
Range
slider to 0 and work only with
Residual Color Desaturation
.
Another application that is more artistic than realistic is using this effect to isolate
colors. Is this useful for a project? For example, perhaps the scene we are working on
has loads of vegetation and this can distract the viewer from the building itself. The
Color section
setting is the key to isolate or remove colors from the image. A value of
0.3
will bring the green color and the different hues, a value of
0.5
isolates the blue
color, and finally, the value of
0.9
isolates the orange\red\brown color.
Color correcting in Lumion
The next step to enhance the image or movie is by color correcting the scene.
Although this expression can have many meanings, usually when we color correct,
it will repair or remove problems with the colors in an image by tweaking and
changing the pixels that make the image.
In Lumion, we need to use the Color correction effect once again found under the
Style
tab, but keep in mind that this doesn't mean you can change a blue pixel to red
or vice versa. Although we have many settings, you will eventually work with just a
few of them such as:
•
Enhance contrast
: This is used to make the shadows darker and bring more
contrast to the image
•
Gamma
: This is something you don't want to change for now unless you
want to change the gamma later in an application such Photoshop
•
Saturation
: This can be a replacement for the previous effect if you are only
looking after changing the saturation of the entire image
As you can see, there is no magic number to color correct an image because every
image or movie is different from the previous one. The main goal of this effect is to
improve some elements in our scene or to do some color grading.
