Good plan. Lock the tripod, set a low ISO, and choose a fast lens—35mm or 50mm will give you a sharp, well‑exposed shot. Use a slow shutter so the beetle’s flash sits in the frame, but keep the aperture wide enough to stay sharp. A reflector can bounce light back into the beetle’s eyes, making it pop. Keep the camera close to the ridge, but not too close—just enough to capture the golden glow without blowing the light. Stay ready to shoot as the light shifts; you’ll need to adjust exposure on the fly.
