What are 10 pointers on photogrophy?

Question

That everyone should know?

Answer 1

off the top of my head:

Subject (what do you want the photo to express)
focus
background (just stand in front of the toilets while I take your photo)
centering or off centre
lighting
shutter speed
colour
close ups
blurring (to give the feeling of speed in sports)

just a few ideas ... hope they help
also, Content (the eye-patch looks better on you than me)
