I've got a new olympus camera (my first 'fancy' one ever) and we got two lens hoods with it. one say Lens hood LH-61C and and the other says Lens hood LH-61D.
I have a faint idea (blocking out the sun so it doesn't hit the lens) but what exactly are they for and what kind of photography are they for?
Answer
Lens hoods can be used in all photography and accomplish two tasks. Foremost, they block unwanted light from entering the lens -- light that would not be in the regular field of view of the picture. Blocking this light reduces "lens flare" and can help provide you with better color saturation for your pictures (less color washout effect). While that's most beneficial in bright light situations they can also help in low-light where there are other bright sources (imagine a cell phone open during a movie).
Second, they help protect the lens from damage. It's harder to hit the surface of the lens, and it can help keep off dust and moisture.
The 61C is for your 14-42 lens and should be flower petal shaped. The 61D is for your 40-150 lens and should be cone shaped.

what is a lens hood ( for cameras?)?
what do you use a lens hood for on a camera ?
why would i need one?
Answer
It prevents stray light that may enter from an angle to the front of the lens from degrading images by ghosting and lens flare.
The flare that can result in "artistic" aiming the lens toward the a light source is intentional and can be quite creative, but the other should be avoided.
Lens hoods can be the first line of defense when shooting under conditions where the lens may be damaged by flying bodies or other objects (sports and off-road shooting for instance).
Here is the result of such an uncontrolled event. Not only was the lens hood damaged, the UV filter was too.
