The program's modular design consists of seven rooms. As you work on an image, you move from room to room, employing the tools tailored to each setting. Real-time imaging is Kai's Photo Soap's hallmark. Brush away red eye, heal a scratch, or push a slider to shift the colors, and the image changes before your eyes. Based on the same technology found in the Power GOO, Kai's Photo Soap performs all editing on a mask, a separate layer that floats above the original photograph.
Painting is different from the method found in any other program.
Rather than applying colors, the brushes apply effects such as hue shifts, lightening, darkening, contrast adjustments, and sharpening. The controls are very precise, allowing effects from subtle to extreme. You can easily save tool settings and zoom levels and recover them with a single mouse click. And because you are painting on a separate mask, you can simply nudge previously created strokes into place. All brushes in a room apply the same effect, however, until you save the image, which merges the original with the mask.
