Part 5

As you can see, the ring flash is used for fill-light and a second flash on the side is the main light. What is great is that you can adjust everything perfectly in advance. Using a grey card, I adjusted the laser focus-points, fill-light flash and main flash. Since the focus point does not move, the light settings do not change either. The tripod's three legs make the frame adjustable in all directions. The lasers and sensors are now set 80cm from the camera plane, corresponding to a ratio of about 1:2. A full frame image corresponds to a 60mm exposure. I'm not yet certain whether this is sufficient for small insects, but additional holes have been bored into the laser supports, allowing for adjustments later. This setup will be too small for butterflies, but at the moment they are not my intended target. I can also mount the 60mm macro lens for a noticeably wider angle. Later I will report on those results.
Here is a frontal view of the unit.
