No, not Cindi Lauper
coming to a town near you. It is your
Photoshop bringing you a way to fix the
colors from what your camera saw to what
your eye saw.
We are using Photoshop
Filter with adjustment layers to change the
colors in a photo. How? Follow
along.
Here is my photo:

I like it, but it is
not the way it really looked. And, I
found some really kickin blue papers that I
want to use with it. The brown just
has to go.

Step 1: Select The First Area You Want To Work On
I am going to select the sky. You can use whichever selection tool you're most comfortable with (Lasso Tool, Pen Too, etc.). I'm going to use the Lasso Tool for this, so I'll select it from the Tools palette. I could also press L on my keyboard to access it with the shortcut. Then with my Lasso Tool selected, I'm going to draw a selection around the sky.

Step Two: Adjustment
Layer
Now that I have my sky selected, I can add my first Photo Filter. To do that, I'll click on the New Adjustment Layer icon at the bottom of the Layers palette. Then
I'll select Photo Filter from the list of
adjustment layers.

Step Three:
The photo filter
gives you two ways to change the tint of
your area--filter and color. Filter
has a preset selection of colors available
for you or you can choose any shade at all
with color picker. I am going with
deep blue under the filters. After
selecting your color, play with the density
slide to get the hue you want. Mine
looks like this right now:

I want to tint the
water too, but am going to "cheat" this
time. Instead of selecting a section,
I am going to tint the entire picture.
I merge my layers and then start again with
a new adjustment layer--photo filter.
I select deep blue and adjust the density.
Problem is now the sand and the surfer have
a blue tint. Still on the same layer,
I switch to a brush and black "paint".
I run my brush over anything that I do not
want colored with my blue tint and it
returns to its regular color.
Basically, I am blacking it out so that it
will not take the color. I merge again
and have:
Started my layout
and ended up adding in a bit of a green
photo filter to really gel with the papers.
