2007 SLP Curriculum Guide #05, Hue Map
Curriculum Guide Index

The Hue Map is a very interesting feature and is one that requires some time to learn and to use in an effective way. Basically, the Hue Map allows one to shift the colors within a photograph. As an example changing the red to blue.

Using Adjust || Hue and Saturation || Hue Map brings up a window where one can shift colors by selecting a particular color and using the slide to create a new color. Some colors in a photograph are a combination of two or more colors in the Hue Map and shifting them will also create a new color.

Unless one is quite technically oriented in regard to how colors and color combinations are achieved, one often needs to initially experiment for a period of time to get the technique of changing colors down. In this fashion the use of this feature takes time and practice. However, once mastered one can change colors with ease.

In addition to shifting colors, one has the option as well to shift saturation and lightness. Thus this feature can brighten, enrich the colors as well as allow color shifting of photographs.

ORIGINAL PHOTOGRAPH

The original photograph is one of my puppy Bear, a toy poodle. The picture is somewhat dark and I want to make the puppy's color richer. Thus in the second illustration, I started out by setting Saturation = 35 and Lightness = 25. This correction initially was satisfactory. I could certainly leave the photograph as is with this initial correction.

Activate by Adjust || Hue and Saturation || Hue Map.

Saturation/Lightness Fix

However, to illustrate how the Hue Map works I choose to make some color shifts. Much experimentation went into developing the color shifts as some corrections changed the puppy's colors too at times.

When beginning to use the Hue Map, and after setting the Saturation/Lightness to your interests, duplicate that layer and then set the Hue Map to its default values. Notice how the ten (10) color switches are set up. Their default values are listed across the top of the color boxes.

Next, study your picture so you can see various colors in it such as the reds, orange's, blues, greens, etc. And, then determine what colors you want to change. In my illustration I wanted to change any or many of the colors except for the puppy's hair.

When learning start with a color box and exaggerate the change in color by dragging the switch. For instance, take the 'Red' Box and change the color to 'Blue'. After first setting the Preview/hide area and setting the Auto Proof then you can watch the changes in your photograph. You can also click on the 'Proof' button to see the original/change to get a better idea of what changes are set by the changes you made with the switch.

Also note that the bottom box values changes as well to help you determine what color changes you want. So, experiment with each of the color boxes and exaggerate the color changes and see their impact upon your photograph. Sometimes a color box change has no effect on the photograph. Sometimes a color box will have an unexpected effect in that the color you thought you were going to achieve is different.

As you experiment with the various color boxes, you will also notice that sometimes closely set colors, such and red and orange perhaps even yellow will work together to blend into a new color. Sometimes other contrast colors when changed will create a new color.

As you continue to experiment you will begin, over time, to get the hang of how to manipulate the Hue Map to change colors in your photograph either in very subtle ways or in dramatic ways. In my illustration, I changed the reds to purples, the blue rug to a green rug and greens to a cyan-blue color. And, I was able to preserve the dog's colors by how I varied both the red and orange box colors.


Values
Red = 343     Orange = 42     Yellow = 328
108-Green = 234     144-Green = 166     Cyan = 125
216-Blue = 140     252Blue = 193     Purple = 193     Pink = 187

Enjoy and have fun learning to use this very neat feature of PSP.
