Shutter speed
Aperture
Fast shutter speeds (
1
/
1600
s in this 
example) freeze motion.
Slow shutter speeds (here 1 s) blur 
motion.
Large apertures (such as f/5.6; 
remember, the lower the f-number, 
the larger the aperture) blur details 
in front of and behind the main 
subject.
Small apertures (f/22 in this case) 
bring both background and 
foreground into focus.
