Thanks, Novel. I agree. I started watching some 1950+ noir detective movies for how they set the atmosphere through camera angle and lighting. It made me go back and change the lighting of my first scene to add more dramatic shadows and change the camera a little. They weren't dramatic enough.
I had thought of switching between views like go to Iso when the detective enters investigation or combat mode or something like that. I'm not sure I want to go through the extra pain. But I will consider it.
I found a pretty nice render setting on my app that gives a duotone image. However, I prefer the comic book render image. It gives a gritty old school feel. I think the trick is to get the lighting right. Here is a comparison of a basic 3D scene (Which has no post-work to make it look nice) and the toon render (which looks too cheery for my story). As well as the comic book post work in a noir style is on the bottom of each.
I like the comic book style on the real render the best. It keeps a gritty feel. I just have to monkey with the lighting to make it not contrast so much that it is hard to look at. May be desaturate it a bit? What do you think? Would the comic book render (bottom left) be something that you can tolerate?
