It seems like you're eager to try how far the camera capable to do instead of telling us your story or your idea behind your shooting...

My 2 cents:
1. Learn post processing with a computer.
2. Bring us a story or theme instead of random shooting, anyhow this sub forum is a showcase. It's an artwork showcase indeed, not a camera showcase.

Post process doesn't mean you need to add additional elements into a picture. The main reason to not use camera's engine to do post process is lost details.

Well, since you are clear on what you want, I am good to keep silent then
