Some easy questions for you. . .

[Rigby470]

I am new to photography and I have a couple of questions which I am certain everyone but myself knows.

1. What does a lense hood do? When is it necessary to use one?

2. Mirror lenses. What do they do?

3. What is a "fisheye" lense?

Thanks in advance for the help.
