Spektrel Art is a stand-alone program and Photoshop plugin which transforms digital photos into "magical art that glimmers and gleams with intersecting lines of tapered light".
What does that mean? Essentially it applies a configurable mix of effects, enhancing edges, smoothing backgrounds and emphasizing colours. Take a look at the thumbnail for one example, and the official product page has more.
Spektral Art works much like any similar tool. Open an image, click one of the thumbnails to apply a particular preset, or click a few buttons and drag some sliders to fine-tune the results.
There's surprising scope for variation, too. For example, just switching from the "Light" to "Dark" theme can transform a bright and friendly image into something dark and sinister, at least in some cases (results vary depending on the source image).
Please note, the demo version doesn't allow images to be saved.
SPECIAL OFFER: as we write, the developer is offering Spektral Art for free. The offer expires August 29th. Please note that you must provide your name, address and phone number to receive your free license.
An interesting application which can create spectacular art from some source images.
