I'm a new bird so take my advice with a pinch of salt. for moving subjects, fast shutter speed like 1/200 or higher to freeze the motion (it depends on how fast is the subject moving also lah...if slow subjects, lower shutter speed also can and vice versa) but you want blurry motion pic, then lower the shutter speed lor.
For f-stop, personal preference is as large the aperture as possible meaning like f 2.8 rather than f 4 lor.....(just in case you wonder why 2.8 is larger than 4 is because it's measured in reciprocally 1/2.8 is bigger than 1/4. Pls ignore if you know this already)
there's of course panning also (do a search on that lah)
