picture has an overall greenish-yellowish hue, and it could do well
with a bit of contrast increase.
of the simplest tools for color modifications is the Image/Adjustments/Variations
feature. The command invokes a sizable dialog that enables you to
do basic color and lightness modifications using preview images.
Let's take a closer look at the Variations dialog:
upper left corner shows two images: the Original, and the
current result of any changes made (Current Pick). The radio
buttons to the right control which aspects (colors, brightness,
etc.) of the photo will be changed. Shadows applies the changes
to the darker areas, Midtones to midtone areas, while Highlights
to the lighter ones. You should select Midtones for general
color modifications. Saturation makes the picture more saturated
or bleached. You can see a slider under the radio buttons. Fine
applies the changes in smaller steps, while Coarse in bigger
ones. It is recommended to use Fine for more accurate work.
Select Show Clipping to indicate whether an area of the picture
"clips out" from overlightening. Using this feature is
lower left section of the dialog shows 7 preview images. The middle
one is the current image, and the surrounding ones represent different
color modifications. If you set the slider to Coarse for
a while, the changes will become more emphasized. (Don't forget
to set the slider back to Fine afterwards.) If Saturation
is selected above, the section only contains 3 images: The current
one in the middle, one somewhat bleached to the left and one more
saturated to the right. Modification couldn't be easier. Click the
variation that represents the direction in which you want your picture
to change. For example, if the photo is too blueish, and you want
to warm the colors up a bit, choose More Red. The variation
you selected jumps to the middle and becomes the current image.
You can apply the same change several times if needed.
lower right section contains 3 images below each other. The middle
one is the current picture, and there is a lighter one above and
a darker one below. This is the section for changing lightness.
the current example, we have selected the Midtones radio
button, in order to change the midtones of the picture. The slider
was set one step right to Fine, to apply the changes in small
steps. In the lower right section, we have clicked the Darker
variation once, so that the photo has somewhat more contrast. In
the left section, we have asked for More Blue three times.
Each click led to more blueish hues instead of the previous green
ones. The exact amount of changes should be chosen according to
the photo and your taste. Click OK to commit the changes
The picture became more definite, more contrasty and the green veil
