This will change each and every color the same amount by shifting its placement in the color-circle. It ranges from -180 to 180 degrees, so you can change a color to its complementary color. It is very useful for removing color cast locally. We used it to remove the purple cast in the girls face below.If you have a blue and rotate the wheel 90° it will become green or purple (depending on the direction), a green will become yellow or blue and so forth. Rotate a blue 180° it becomes yellow - as we did in the example where we targeted the blue sky and left the trees unchanged. Please see the example of its practical use below, where we used it to change the tone of the girls face.
This plug-in gives you full control over color editing. Address individual colors and target the retouch to adjustable lightness levels. Also you can apply a graduated effect.This is the Color Corrector plugin’s control panel. Click on the image for a larger view.It works with the following image modes:8 & 16 bit/channel: RGB, CMYK, Grayscale, Duotone, Lab.
The first three sliders either raise or lower the specific color content of the hue being edited. They control the RGB (Red, Green, Blue) channels of the image, so removing a color will appear as an increase of its complementary. The complementary colors are...
Cyan - RedMagenta - Green Yellow - Blue Regarding cyan, magenta and yellow in an RGB image. If you want to make dark colors any of these three, you will probably have to raise the two others. F.ex. to make a dark color cyan, you have to raise green and blue rather than lower red.Midtone priority. When this is selected the changes will integrate naturally into the image.
Here we targeted the reflected lights on the girls face and changed them to the warm shades of light reflected from sand and water.First we used color-range to include only reds and magenta. Then we used brightness-range to exclude the bright colors. We shifted the entire spectrum 20 degrees, but did not want to change the shadows completely. So we set the target to the lightest value of the brightness-range (165) and the softness to 80%.
Brightness & Saturation
Basic brightness and saturation can be controled with these two sliders.
In addition to the three luminance levels, you have saturation levels. The two sliders determine how much saturated and unsaturated colors are to be changed.
These controls are common for many of the Power Retouch plug-ins. Using graduated effect will cause the filter to apply it's filtering at full strength in one side of the image and then fade the effect out towards the other side. You can change direction by right clicking the preview. Midpoint will shift the balance between how large an area will be filtered at full strength and how much will have a faded out effect. Contrast will change the acceleration and spread of the fade-out.
In this example we applied a graduated effect to the foreground. By warming it up we created a greater sense of depth and also balanced the slight greenish cast.
Dark limit - colors darker than this sliders value will not be changed.Light limit - colors lighter than this sliders value will not be changed.Target - colors with this degree of lightness will be changed the most (but if the softness-slider is set to 0 all will be changed equally).Softness - 100% will force the color changes to be applied at full force only to colors that match the target value in brightness. The effect will diminish the further a given color is from the target value in brightness. When set to 0% all colors that are between the dark limit and
the light limit will be changed at full force. Settings less than 100% narrow the range that gets changed at full force and widens the effect of the fade-out range. So 100% will softly integrate any changes. This set of controls is very useful if you want to only edit the hue of a shadow, for example.
Colors to the right of the From slider and to the left of the Up to slider will be changed. You can place the top slider to the right of the lower one to include both blues and green (f.ex). All will set the sliders to include all colors.These range controls are also good for targeting background colors for single editing. In the example below we targeted the blue background color of the sky.
When you check the Mask Unchanged checkbox all colors outside the limits set by the brightness-range and color-range will be colored with a monochrome color. In this case it is red, but you can change the color by clicking in the colored rectangle.This is the before and after image. We simply reduced brightness to deepen the overexposed sky. We did not change the color -- so in this case you could have done the same with the brightness editor plugin.
These controls are common to most of the Power Retouch plug-ins. The displayed histogram will be for the area in the preview. You can choose between individual color channels, all color channels or luminance.Anti-posterization should be set as low as possible. In most cases leave it off (at 0).The color picker allows you to pick a point (pixel) in the preview and get some interesting data about it. The d-values tell how much the pixel is changed in percent. L tells the luminance value (brightness) of the pixel.
