"F-stop" is the same as "aperture setting".

Wouldn't a post like this be better suited to Talk About Photography? Surely you do not need a pro's input on this one eh?

Do a class in your area, it's easier than reading about it. Or read then experiement.

I agree, we all started at the bottom. look into a photography 101 class or adult education. I imagine if you didn't know what an F stop was, there are many other basics you want to learn as well. It's nothing to be ashamed of. A friend of mine never took his digi cam off automatic for over a year! he was missing out on a lot of fun and experiments katt

Your F stop is one of the three major values that you can adjust in your camera. (F stop, Shutter Speed, ISO).
If you are just starting out I would recomend going through Canon's free tutorial for entry level DSLR users.

I'm just starting to figure out what I'm doing and the link above helped a lot. A cheap lens to get you started with portraits would be the 50mm 1.8


http://www.amazon.com/Canon-50mm-1-8...e=UTF8&s=photo

There are better lenses out there, but this is the one I decided to start with

as others have said it is the aperature value. in laymens terms it means how much you want in focus from the actual focus point - at f4 you will have less in focus around your focus point than at f8 and so one as the fnumber increases...

Lot's of good advice above, but I have to disagree somewhat with symes on this. Although he's quite right in that the aperture does indeed radically effect the depth of field and what appears to be acceptably sharp in front of and behind the actual point of focus, it's really to do with the amount of light that the lens is allowing in. A small f number (say f/2.8) will let in a lot more light than a larger number (say f/16). Even that's confusing in that the smaller number is actually a larger aperture

Don't worry about it though, read up on it and try out various settings on the camera. After a while it will all start to make sense.

Yeah, it is a super one. Though it does make me want to go out and buy more glass.

An F stop is like a bus stop, except for one little thing...
