To install, simply unzip and copy the plugin file into your Photoshop plugins directory. It's as simple as that! If you run into problems, try the step-by-step instructions below:
That's all you need to know to get started!
Brightness: This changes overall brightness of the image similar to the effect of the Midtones slider in Photoshop's Levels adjustment.
Contrast: This increases contrast in the image by applying a s-shaped curve to the image. This is equivalent to using a s-shaped curve in Photoshop's Curves adjustment.
Brightness/Contrast Adjust: This control changes the Brightness and Contrast algorithms and alters their effect. Higher values tend to make the image appear more pastel. Lower values will make saturated colors darker. This value does nothing if both brightness and contrast are at neutral positions.
Saturation: Higher values increase saturation. Saturation is never increased in a way that would cause clipping. Each pixel is evaluated individually. Negative numbers can be used to create negative saturation.
Luminance compensation: This control changes the saturation algorithm. If set to 0, luminance compensation will be disabled. Without this, increasing saturation will increase the luminance of saturated colors, making them brighter than they should be. The default setting (1.0) will maintain constant luminance so that saturation adjustments do not affect luminance at all.
Luminance coefficients: These are the co-efficients, or weightings, used to calculate luminance. Changing these settings will adjust the weight given to each color in the saturation algorithm. In most cases the effect is subtle and you do not need to adjust these parameters.

Black & White Conversions
Set Saturation to 0 to convert an image to black and white.
The luminance coefficients settings for red, green, and blue can be used to simulate color filters used in black and white photography. You can think of the luminance coefficients as weights being given to each color. Reducing the blue slider will reduce the weight given to blues and vice versa. This can be used to make skies darker or brighter when converted to black & white.
The images below show a black and white conversion with the default settings and with only blue contributing to the
The comparison below shows the effect of changing the luminance coefficients from the default to weight blue as much as possible. In this case, this was done to create contrast between the sky and the church to enhance the composition of the picture.
Photoshop CC: Adobe may install both a 32-bit and 64-version of Photoshop CC. Copy the filters into the respective folders. Make sure that you are running your desired version (32/64) of Photoshop CC.
(For selective color only) Monitor resolution at least 1024x900.
