The Portrait & Family Set features filters for converting your color images to black-and-white, enhancing colors, warming them, simulating moonlight and more. All of the filters use simple slider controls to change the look of your photos. A preview window lets you see the effect of your settings before you apply them.

This arrangement works well, and I found the filters fast, easy to use and effective. The Enhance Colors filter, for example, boosted color-laden areas of my images while leaving more neutral shades alone. Without much ado, I got natural-looking, but colorful photos that otherwise would have taken much longer to enhance and required adjustments with multiple Photoshop tools.

The Outdoor Set is as simple to use as the Portrait & Family Set, and offers two virtual graduated filters (one blue and one neutral-density), a polarizer and other filters. The graduated filters and the polarizer do a good job simulating the glass filters for which they’re named. The graduated blue filter nicely cleaned up an informal portrait that had a dull gray background, quickly adding sparkle to the picture.

The polarizer functions just as efficiently, and while it’s not quite a replacement for the real thing, it works when a real polarizer wouldn’t—that is, whenever the sun is far from 90 degrees off your line of sight.

The filters in both sets are compatible with Photoshop and many other image-editing programs, and work with 8-bit images—JPEGs and most TIFFs. List Price: $65 per set.
