I posted a picture showing how I arranged the lights and their intensity. I hope this would be helpful to you. This is my principle of lighting: lights are arranged to set off the main features. Invariably, I will adjust light arrangement in the production process until I’m satisfied. When you have time, you can get some good posters to train yourself on how to arrange the lights.
Regarding rendering, you can read that number of the magazine. It should have been published on the magazine in August to September last year.
