Lumen Tool

This is a lighting simulator for 3D portraits, which sounds genuinely useful for portrait photographers who want to experiment with different lighting setups before actually building them in real life. It's the kind of tool that could save real ones a lot of trial and error — you could dial in exactly where your key light, fill, and rim light should go and see the result instantly. Whether it nails the preview quality is the real question, and I'd need to see it in action before saying it's the move or just another experiment that looks better on paper than in practice.
