3 - Remedy an Incorrect
White Balance Setting
If the white balance was set incorrectly, you can use a filter to
compensate for the wrong setting.
Use the Magenta filter to remove the green from fluorescent lights.
The orange of tungsten lights (light bulbs) can be eliminated by
using the Cooling Filter (80).
Local Color Changes
You can change the color in only a portion of the photograph by creating
a mask.
Go to
One Color Is OK, Correct the Second Color with Masking and
Two Areas with Poor Color.
Twenty Choices
When you you create a Photo Filter adjustment layer, you can choose
from twenty filters.
You can also create your own filters.
This will be described below.
Chart
The chart below describes the filters in more detail.
Beginners may want to skip ahead.
The most useful filters are in bold face.
The values in the Red, Green, and Blue columns are luminosity levels
(0 to 255).
A change in one luminosity level is equivalent to a change of about
.4% in a color.
When a value is negative, its positive value equivalent is given
as well.
For example, -6 red and
+6 cyan are equivalent.
The filters are at 25% Density with Preserve Luminosity selected.

Photo Filters v. Hue/Saturation v. Filter
There are two other ways to use similar filters.
Why are Photo Filter adjustment layers better?
Hue/Saturation Adjustment Layer
You could use a Hue/Saturation adjustment layer to do what a Photo
Filter adjustment layer does.
However, you won't have twenty pre-made filters from which to choose.
Filter > Adjustment > Photo Filter
You could use a filter from the Filter menu.
Go to Filter > Adjustment > Photo Filter.
However, the filter is applied to a layer with pixels.
If you want to modify the filtration, later, you can't.
There's no Photo Filter adjustment layer to reopen.
Example
Be sure to check off as you go along.
Preparation
1) Preserve your
original file.
If you haven't already done so, go to
Preserve
Your Original File.
2) Create a Background copy layer.
If you haven't already done so, go to
Create a Background Copy Layer.
Photo Filter Adjustment Layer
1)
Create a Photo Filter adjustment layer.
The Photo Filter window will open.
2) Select Warming
Filter (81).
The default density is 25%.
Try this setting.
By default, Preserve Luminosity is selected.
The filter will not change the exposure of the photograph when Preserve
Luminosity is selected.
3) Click OK (Pre-8.0 only).
Compare
Compare the two versions using the eye icon (Pre-8.0), or the
eye/red/arrow icon (8.0).
Too Weak
If the effect isn't strong enough, return to the Photo Filter
adjustment window and increase the density percentage.
Too Strong
If the effect is too strong, reduce the opacity of the Photo Filter
adjustment layer.
Here's the original, the warmed up version using Warming Filter (81),
and a cooled own version using Cooling Filter (82).
Original
Warming Filter (81)
Cooling Filter (82)
Make Your Own Filter
You can choose the color for a Photo Filter adjustment layer.
Double click the colored square next to Color, in the Photo Filter
window, to open the Color Picker.
Choose a color, and click OK.
If you haven't already done so, go to
Color Picking.
Local Color Changes
As mentioned, you can change the color in only a portion of the photograph
by creating a mask.
Let's say you have a photograph with two areas of color.
For example, a person illuminated by sunlight and the cyan-colored
sky in the shadows.
If one of the areas of color is acceptable, but the second area isn't,
go to
One Color Is OK, Correct the Second Color with Masking.
If both of the areas of color are not pleasing, go to
Two Areas with Poor Color.
Saving the Photograph
If you haven't already done so, go to
Saving Files.
