You have two ways to control how bright and how dark your pictures are.
You can have a slow shutter speed, 1/2 second 1, 2 ,4 seconds. These are great for night time.
But during the day these slow shutters will make you pictures to bright.
Then you have the fast shutter speeds, perfect for daytime and action photography, these 1/1000, 1/2000 and even 1/4000 all mean that the shutter is open for that small fraction of a second (read 1 thousandth of a second or 1 two-thousandths of a second and the fastest my camera has , 1 four thousandths of a second. So a slow shutter speed will allow more light, but will blur if an object is moving.
The other way to control exposure is using F-stops.Which have been mentioned, think of your pupil and how it changes size, in low light your pupil will expand, and in bright light it will shrink.
If you change this F-stop then you can control the Depth of Field. What I mean by that is how when your subject is in Focus, will things in the foreground and the background be clear also?
Its hard to explain.
When you do a set of 3-5 images to make into an HDR be sure to change the SHUTTER SPEED only, this will leave the Depth of Field the same for you pics, let the shutter control how bright the pictures are.

he knows that....he was referring to the fact that his camera is not affected by DoF as much as a DSLR.
F5.6 and F9 would look almost identical with his camera. especially at a wide angle.

Nikon and sony use the same sensor.
Canon and Fuji make their own sensors
the new fuji uses a nikon body
IMHO, canon has the nicest lens line up
unless you're doing weddings or lots of indoor shooting, 30D > 5D
the only thing the 5D has over the 30D is a FF sensor. 30D wins in every other department pretty much.
D80 is pretty impressive, and generally Nikon cameras have more options than canon. and many prefer it's ergonomics
pentax is packed to the nuts for the price.
pentax lacks a lens selection
in the end, if you're buying an entry level DSLR, it comes down to brand preference and lenses.
