In this lecture I will discuss several filters.
I will start with three filters
that make images look warmer.
In the last lecture we have already seen
the 'Brilliance / Warmth' filter in action.
A filter that is related to it,
is the 'Sunlight Filter'.
I have opened: 'Sun_forest'.
I would like to add some sunlight
to this image.
At the bottom I select: 'Sunlight'.
You can adjust the Light Strength,
the Light Temperature,
the Brightness, Contrast, and Saturation.
Now we have a bit sun in the image.
The next warming filter
is the 'Skylight' Filter.
I have opened: 'Woman_beach'.
The 'Skylight Filter' removes blue casts
and warms the image up.
With the 'Foliage' Filter you can bring
the greens in nature images, to life.
There are three presets.
I will choose: 'Method 2'.
Under it I can set the strength of the filter.
Now we will look at two color correction filters.
I have opened: 'Bride'.
To color correct this image, and remove 
the blue color cast from the wedding dress,
I will select the 'White neutralizer' filter.
At the right, there is a color picker.
If I click on the dress,
it will remove the blue.
At the left of the color picker, I see the color
I have chosen to become neutral.
Another interesting color correction
is 'Remove Color Cast'.
I have opened: 'Town'.
By dragging the Hue slider,
you can quickly find the optimal point
for neutralizing the color cast.
In the previous lecture we have seen 'Structure'
in action in Viveza.
Color Efex goes further, and offers six contrast filters,
which are all based on the 'Structure' algorithm.
Let's have a look.
For getting a more dramatic look in your image,
you can use: 'Dark contrasts'.
I have opened: 'mountains_snow'.
I will drag the Contrast up,
and also the Brightness.
I will now increase
the 'Dark Detail Extractor'.
With Shadows / Highlights protection,
you can bring the effect down a bit
in the Shadows and Highlights.
The next filter is 'Contrast Only'.
I have opened: 'Rose'.
With 'Contrast Only' you have control
over how contrast is applied.
You have 'Normal Contrast',
followed by 'Contrast Only',
which prevents colors from being affected,
and 'Soft Contrast',
which gives softer transitions.
If I now select the 'Dark Contrasts' filter,
we see we get a different result.
Another contrast filter
is 'Contrast color range'.
I have opened: 'Bride_and_groom'.
The color selected with 'Color',
will cause objects of that color to become lighter,
while opposite, or complementary colors
will become darker.
This is a quick and effective way, to get
better contrast
between the bride and groom,
and the background.
I have opened: 'Flowers'.
With 'Dark Contrasts', we made lighter areas darker,
to give them more drama.
With 'Pro Contrast', we do the opposite, 
and lighten up areas in a dark image.
The flowers are now much more visible.
I have opened: 'Ocean_rocks'.
With 'Detail extractor', you can bring out
detail in an image in three ways.
Under 'Effect Radius', you can adjust
fine detail,
medium detail,
or larger detail separately.
And finally, with 'Tonal contrast',
you can bring out detail in the Highlights,
Mid-tones, or Shadows.
There are also five Contrast Types:
Standard, High Pass,
Fine, Balanced, and Strong.
In this lecture,
we have used the filters globally.
For more refined results,
you can use the Control points.
In the next lecture,
we will look at creative filters.
