My setup for this was quite simple. I used daylight from a window combined with the light from a single, small LED source. The camera was a Fuji X-T2 fit with a Zeiss Touit 60mm macro, which I used wide open at f/2.8. In the top photo I shifted the color temperature towards a cool blue. In the second photo I sought more of a pure, bright, white light. I also used some of the white solar bursts from my Sunshine Overlays package to brighten several areas on the images.
The bottom photo was more of a complex setup. Here I used two small LED lights and different globes photographed against a black background. I took several views showing the different continents. Later I placed three of these views in Photoshop as layers on top of one another. Since they were photographed against black I was able to use the "Screen" layer mode to allow seeing through to the layers below. "Screen" mode will make everything black disappear. Next I added two more layers of blurs taken of out-of-focus lights. One of these layers was changed to "Soft Light"; the other remained "Normal" but the opacity was dialed down. This gave me a total of five over-lapping layers. Finally, I added layer masks to several of the images so I could paint out some of the overlapping areas where they interfered with one another.
