Open Original
I find this feature especially useful for correcting color casts from scanned images. It is also a useful tool for the novice to make quick corrections to any digital image. For this article, I selected our wedding picture from 37 years ago. The image was scanned a couple of years ago when it was already horribly faded and had a yellow color shift. After you open your image select FILTER PACK from the COLORS menu. - 2
Filter Pack
The filter pack allows you to make a variety of changes by simply clicking on what you want. Notice that you can apply the filter to a selection or the entire image. To apply it to a selection you need to make your selection prior to opening the filter pack. You can also choose to apply the filter to the midtones, shadows or highlights. Each "window" will open up a series of selectable variations based on the choice. - 3
Hue
The primary change I want to make to this image is a hue change. After making the hue change, I can then decide if I want to adjust saturation or value. Hue, saturation and value (lightness or grayness) are the three elements of the tri-stimulus color model known as l*a*b or LAB color. In effect, the FILTER PACK allows you to change the working color space or gamut of the photographic image. When I click on HUE, a window of variations opens allowing me to click on one. As soon as I click on the variation it is shown in the "current" image preview. - 4
Saturation
Once I make the hue change and click OK, the image will render in the editing window. If I like it I can save it to a new file name or click on FILTER PACK to make other changes. In this case the image was still too saturated, so I opened the SATURATION window and selected less saturated. Click OK to render the image or click on VALUE to make changes to the value. - 5
Value
I didn't want to make any changes to the value for this image, but you can see you are again given three basic variations to choose from. Once you click on any variation in any window, a new variation selection will be presented allowing you to darken or lighten the image again. - 6
Advanced
The ADVANCED menu provides additional fine-tuning allowing you to adjust the actual midtones, shadow and highlight of the image. The changes are seen instantly in the preview window. You can even change the size of the preview image. - 7
Final Image
The final image is a great improvement over the original scan. Resolution lost is never regained and the degradation of the photo due to time, heat and humidity can never be fully recovered. However, images can be greatly and quickly improved using this neat little applet. I don't know why they call it FILTER PACK; it has little to do with camera filters. It is really a LAB or HSV gamut correction tool. In any case, it is another example of an application within a program that can really help anyone make quick image corrections.
