I am setting the f-stop to the lowest possible number (f-2.8) to get a blurry background, but it just doesn't give me the blurry background I want. Its the same exact as an ordinary picture. What am I doing wrong?

To create that blurry background you have to have more than just large aperture. You have to try using the longest lens to fill the frame. But if the subject is so far away that the subject and the background is considered "infinity" then everything will be in focus again. So the subject has to be somewhat close than the camera lens' infinity setting.
So basically just keep stepping back until something "clicks".
Good Luck.

The only other way to change your depth of field besides the aperture is by changing the position of the lens relative to the film plane, also refered to as the scheimpflug principle. But to get the desired affect that you are looking for try simply a longer lens, perhaps 200 or 300 mm in combination with a small aperture such as f2.8

If you're using a digicam its really hard to control depth of field due to the small sensor size.
If you're using a zoom at its widest setting (say a 28-200mm) of 28mm then its hard to control depth of field.
Try using a longer focal length, say 100mm, wide open (f2.8).
New edit: Note to Michael D. After 36 years of enjoying photography I can assure you that shutter speed has ABSOLUTELY NOTHING to do with Depth of Field. DOF is totally a function of the lens focal length and the f-stop used.

You apparently don't really understand what depth of field really means. If your background is within the same range of your subjects depth of field you won't see a difference. Film or digital? Focal length that you are using? Distance between subject and background?

It's not the aperature that determines depth of field, it's the shutter speed. 1/60 will get you more depth of field than 1/500.On a film camera and some expensive digital ones, there is a small button to the left of the lens, this should actually show you your depth of field before you shoot the picture.
