Memory-Color Makeovers (continued)

Immediately you can see that the Green and Blue values are almost identical — which signals a color problem immediately: Blue values should be approximately 25% lower than Green values if they are supposed to be in a 4/3 ratio (around 121, let's say); using our 5/4 target ratio of red to green, the Green values should be approximately 161 instead of 177.

7 Click and hold the Eyedropper tool in the toolbox until the two "hidden" tools appear; select the "hidden" Color Sampler tool.

The Color Sampler tool allows you to record the RGB values of up to four areas in the Info palette.

8 Using the Color Sampler tool, click the sunlit (image-left) side of the forehead.

Using the Color Sampler tool, sample and record the initial color value of 203/177/172.

9 With the Color Sampler tool still active, sample and record a second set of RGB values on the cheek.

Here your RGB values should read 194/165/ 152 — also not within the range associated with our 5/4/3 ratio. To get these numbers in line, we need to move them to 194/155/116.

Taz's Take: It's always a good idea to work with at least two sets of RGB values. Doing so ensures that you're working with representative RGB values. Also avoid sampling areas in shadows; sample the lighted areas whenever possible.

The Curves dialog box appears.

! In the Curves dialog box, choose Green from the Channel drop-down menu.

You might like to work in order from Red to Green to Blue, since that is the ratio order.

@ §€/Ctrl + click sampled point #1 and then §€/Ctrl + click sampled point #2; this adds control points associated with skin-tone values to your curve.

Since you are very specifically targeting the skin tones in this image, it is appropriate to locate the skin-tone areas on the curve and use those points for making the curve adjustments.

Note: Since both points end up being so close together, you can click and drag one of the points off the curve graph, so that just one point remains for adjustment purposes. The second point stays in place.

# While monitoring the sampled values in the Info palette, click and drag the sampled point on the curve downward until the #1 sample Green value is approximately 163.

Note that the Green value at the #2 sampled point is now 152 — very close to your #2 target value of 155.

$ In the Curves dialog box, choose Blue from the Channels drop-down menu.

One more color to go.

% Press 36/Ctrl + click the #2 sampled point to add a control point associated with that skin-tone value to the Blue curve.

Again, it makes sense to use a control point associated with skin tones here.
