1. Installation
Move or Copy the filter plug-in to your Photoshop filters folder, (re)start Photoshop, then the filter should be available under:

filter --> theimagingfactory --> Chromex I...

TIP: To assist in finding the best values you can reset values to the last used setting by holding the alt-key while selecting cancel.
To reset values to the initial defaults, hold both the alt-key and shift-key while selecting cancel!

2. Preview
This plugin shows the results of its calculations in a preview pane. To better judge the effect of your settings the preview can be zoomed by the zoom-buttons below the preview pane indicated with a "+" (plus) and "-" (minus) symbol. Alternatively you can use the cmd-"+" or cmd-"-" key sequence.

A percentage of scaling is given between the zoom buttons. You can click the percentage text to quickly switch between 100% and best fit. If the preview is larger than the preview pane you can scroll through the preview by clicking the mouse in the previewpane and subsequently draging the preview.

The preview checkbox next to the preview pane allows you to switch between previewing the original data and previewing the filtered data. Mac users can use the ctrl-space key sequence to quickly switch the preview checkbox.

3. Color Patches
The color patches indicate the "source" and "destination" color respectively. The currently active colorpatch is indicated by a thicker frame. The color sliders affect the currently active colorpatch!

You can select a "source" color by clicking the source colorpatch. It becomes active (indicated by a thicker frame) and the color sliders will reflect the color. You can now select the color you want to change, by clicking the preview and adjusting the color sliders.

note: for optimal results it is best to change the source color saturation to its maximum value.

You can select a "destination" color by clicking the destination colorpatch. It becomes active (indicated by a thicker frame) and the color sliders will reflect the color. You can now select the color you want the source color to be changed to, by clicking the preview and adjusting the color sliders.

Alternatively you can click the source or destination colorpatch while holding down the alt-key. This will bring up the photoshop colorpicker.

4. Color controls
Use the color controls to adjust the "source" and "destination" colors. The color controls are hue, saturation and brightness sliders. Which colorpatch is controlled depends on the active colorpatch. The active colorpatch is indicated by the thicker frame. To activate a colorpatch simply click the colorpatch once.

Alternatively you can click the source or destination colorpatch while holding down the alt-key. This will bring up the photoshop colorpicker.

5. Range
The range parameter determines the number of hues which will be considered for correction. The larger this value, the more of the surrounding hues will be corrected also.

6. Known issues and incompatibilities
- For the NT family of OSes this plugin requires Windows NT 5.0 or higher!
- The windows versions will occasionally not update its values when first selecting a slider followed by immediate dragging. In this case, briefly release the mouse, then resume dragging.
