Oh. If you want your picture to be entirely (or almost) in focus, you need to stop down the aperture of your lens. Anything from f/8-f/16 should be ok. Keep in mind that with your lens stopped down that much, you will need a lot of light (either natural light, from a flash, strobes, etc..) or else your shutter speed will be too slow. If you have a tripod, then you're fine.
Also, most photographers edit their pictures and usually add some detail in photoshop to make the pictures look more crisp than they would look straight from the camera.
