We've talked a lot about establishing and sticking to a workflow. This is very important when working professionally. An effective workflow can increase your productivity. We've also asked ourselves a lot of questions about our scene so that we can understand what's happening in our scene better. It's almost impossible to light a scene if we don't understand what's going on. These questions are aimed at guiding us and giving us a better understanding about where our scene is coming from, and it is at the moment we want to portray, and where it's going. If we can imagine that our scene has the potential to exist somewhere in the real world, then it will be a lot easier to produce a realistic result.
