Here is my step by step show process for the lighting of scene 25. Keith asked me to light the scene so it could be rendered later during the day. Time was of the essence so it had to be done quite soon. Here I went with the idea of less is more, so I only create as many lights as were necessary, 2 directional lights for some simple lighting of the cave and 2 spot lights for the light coming down the tunnel which is whats illuminating the eel and child. I showed Keith my inital tests, and he said they were just too bright and after going through some other scenes and renders, I understood if had to be much darker and more atmospheric. I then deleted 1 of the directional lights and dropped the intensity down on the spot lights. I had shadows being cast from one of the spot lights, using ray traced shadows. I think the lighting is decent, and a lot of tweaking will be done in post so all that is needed is a good base which I think im close too having.
