With that lens and sensor, f/11 is probably as far as you can go without starting to see light diffraction damage the quality of the image. You will be surprised at how much DOF that f/11 will give you.

You use the colored filters after the shot now in digital processing. It really works. There are a lot of things you can do with the color response in digital processing. I use Nik Silver Efex but that is expensive. There are less expensive ways to do it. Thanks goodness I'm not still using the wet darkroom. LOL

Get started and experiment.
