There is one patented software program that is crucial to my work. It is Lucis® Pro 5.0 by Image Content Technology LLC (ICT), which is also my company. Lucis Pro 5.0 is stand-alone PC software. There is a "lite" (but still powerful) version of Lucis Pro called LucisArt. LucisArt is available for PC and Mac and it is an Adobe® Photoshop® plug-in.

There are whole web sites devoted to Lucis Pro and LucisArt so I won't repeat that information here. But I will attempt to explain why Lucis Pro is so crucial in the creation of my art. With Lucis Pro, I can select a range of contrast variances that I would like to see more clearly. Lucis Pro maps out contrast variances by comparing each pixel to every other pixel along hundreds of radial lines. Contrast variances within the selected range are enhanced and contrast variances outside the range are diminished. So how the image is enhanced depends on my selections and how intensity varies within the image. If I select a mid-range of contrast variances to enhance, then both the smaller and larger variances are diminished. This pulls out mid-range contrast patterns.

Lucis Pro shifts the relative emphasis of intensity variations.

When I work on an Interplay Image with Lucis Pro, the mixed image is smoothed or enhanced based on the relative intensities of each image with respect to itself and to the other image. An interplay between the two images is created. This is difficult to describe without actually using Lucis Pro.

If you visit the Lucis Pro site please look at the section on how Lucis Pro works, especially the multiple luminance channel mode (RGB mode). With RGB mode I can enhance each RGB channel separately. This alters both detail and color, and involves the use of six parameters. It has taken hundreds of hours of practice to develop my expertise with Lucis Pro.
