The Coolorize filter contains two sets of RGB sliders; the sliders are used
to set the range of colors that you would like to desaturate toward black (#3).
For example, a setting of 64 in the first Red slider, and 192 in the second
Red slider, would cause no changes to dark reds (with a value of less than 64)
and bright reds (with a value of greater than 192). Reds with a value of 64-192
would be desaturated toward black.

The autumn
landscape after applying the Coolorize filter’s Twilight
option. Images that are actually shot at twilight tend to have
relatively high red and green values, and comparatively low blue
values, so it’s important to keep this in mind when adjusting
the sliders. There’s normally a limited amount of light
available when shooting twilight images, the Twilight filter mimics
this effect by placing a semitransparent gray scale pattern over
the image. If you look closely at this image, you’ll see
that the gray scale pattern has caused it to become darker along
the left and right edges. This effect can be decreased or increased
using the Coolorize Intensity slider.

Creating A Twilight Photo With The Coolorize Twilight Option
After selecting Twilight in the Coolorize drop-down box, the most productive
way to create a twilight image is to click the Reset button (#4) (which probably
should be called the “Random” button) a few times, until you find
something that’s close to what you have in mind. You can then fine-tune
the effect using the sliders.

The Plugin Galaxy Zoom Filter
The Zoom filter is used to zoom in on and magnify a particular area of a photo,
leaving the rest of the photo unaffected by the zoom. It’s an effect that
can be accomplished in Photoshop, but the process is a bit time-consuming. Using
the Zoom filter, you can select the zoom area, a color and shape for the area’s
outline, and a magnification factor, all from within a single dialog box. Images
#5 and #6 show a typical use of the Zoom filter.
Panopticum’s Plugin Galaxy for Photoshop is available at: www.panopticum.com/ps/pg/galaxy.shtml.
The package retails for $50, and a demo version is available.
