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 --> White Balance...
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. White Balance Section There are three sliders available in the White Balance Section. These allow you to correct or change an image's white balance. The first two sliders allow you to correct for differences between the original scene's color temperature and the camera white balance setting.
Set the "Original Scene" value to the color temperature of the lighting of the original scene.
Set the "Camera Setting" value to the color temperature that your camera was set to during the actual shoot.
The image will then be "neutralized" according to those settings. To create an additional white balance, the "Adjust WB" slider can be used to make the image appear "warmer" (lower values) or "colder" (higher values).
This slider can also be used to quickly adjust an image white balance. In that case leave the top two sliders at equal values. (The bottom slider adjusts the white balance relative to D50).
4. White Point Section
Unfortunately, when a camera is set to an incorrect white balance during a shoot, it will compensate exposure to ensure maximum contrast. This basically means that absolute white (R=G=B=max) is available in the resulting image, although this would not be correct because of temperature differences.
Correcting the temperature difference without compensating exposure again, will result in absolute white being contaminated by the new color temperature white balance. If the overall image is to warm (Red) and is corrected towards cold (Blue) the resulting whites will turn blue.
To leave absolute whites as they are, turn on "Lock Original Whites" by checking the appropriate checkbox.
To compensate exposure, turn on "Compensate Exposure" by checking the appropriate checkbox and slide the control to the value desired.
5. 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.
