Here is my RingLIght Camera. This is a sub-scene. See the readme file included in the zip file.
It loads ready for a figure in the zero position. Ringlights have the distinction of being rather "flat" on the face. They provide a stark look as you can see from the sample images.
To install, copy the Scene Subsets folder to your My DAZ Library folder.
To use, go to your content->Scene Subsets folder and double-click on the db Ring Light icon.
