Hello, I have a basic understanding on shutter speed, aperture and how aperture affects DOF. Since I got my camera, I have been taking pictures in manual mode playing with different settings. But I was wondering if there is a rule of thumb on what f-stop do you use for different photos you are taking. For example, if you want to take a landscape photo, what f-stop will you use? Same thing for sport, portrait and etc. I realized I might learn this as I take more photos and gained more experienced. But I think those rule of thumb settings will help a beginner. If you have any advice to share, I would really appreciate it.
