How to make my background normal?

Sup guys, I just recently purchased a Nikon D3000 camera and i've been messing around and i love it 100%… I was just how do i make my background smooth when i'm taking pictures of a person… I love that it makes it blurry to catch a sweet face but sometimes i want the person's face with the background clear? Best answer max points!

If you want a blurred background, use a large aperture. If you want an in focus background, use a small aperture. You should pick up a photography book or two… This is really basic stuff.

For blurred background, use large aperture size (small f/number). For sharp background, use small aperture size (large f/number). Shoot using aperture priority mode to be able to select aperture size.

Besides the aperture, there's the focal length.
Longer focal lengths will blur the background

Shorter focal lengths leave the background looking sharper

Simply put it's all about the lens and the light. More light, more in focus your background can
be, not always but can be. The less light the opposite is true.

Less light means more aperture, more light less aperture.

Here's a good article on the subject.
http://en.wikipedia.org/...h_of_field

Bump your aperture from somewhere around 5.0 to 8.0 and also don't stand to close to your subjects.

What you are asking about is called Depth of Field (DOF). There are only three factors that affect your DOF:

1) The focal length of the lens.
2) The f-stop used.
3) The subject distance.

At http://www.dofmaster.com/dofjs.html you can learn about DOF and how to control it. Then you can use the DOF Calculator to compute DOF for any combination of the three factors imaginable.

55mm @ f16 focused on a subject at 10'-0'' DOF will be from 7'-7'' to 14'-7''. Anything from 2'-5'' in front of your subject to anything 4'-7'' behind your subject will be in focus.

55mm @ f5.6 focused on a subject at 10'-0'' DOF will be from 9'-0'' to 11'-4''. Anything from 1'-0'' in front of your subject to anything 1'-4'' behind your subject will be in focus.

35mm @ f16 focused on a subject at 10'-0'' DOF will be from 5'-7'' to 47'-0''. Anything from 4'-5'' in front of your subject to anything 37'-0'' behind your subject will be in focus.

35mm @ f5.6 focused on a subject at 10'-0'' DOF will be from 7'-10'' to 13'-11''. Anything from 2'-2'' in front of your subject to anything 3'-11'' behind your subject will be in focus.

As you can easily see the differences in focal lengths and f-stops makes a huge difference in your DOF with a subject only 10'-0'' away. You can continue the experiment with different subject distances and f-stops and focal lengths.

Of course your subject at 10'-0'' will appear smaller when taken with a 35mm focal length than it will when taken with a 55mm focal length. Although this site compares a 35mm and 50mm focal length you can see the difference. A 55mm focal length would show even less than the 50mm focal length.http://mansurovs.com/lens-zoom-on-dx-15-crop-factor-cameras
