SLR Camera Questions

First of all, I've never been into photography, I just have a 6 year old Sony point and shoot, and I'm about to get my mom's Kodak Easy share since she just got a Canon Digital Rebel. I've taken a few pics with it and it does a great job.

My question is - Why do SLR cameras always blur the background of a picture? Sure it looks nice in some cases but what if you want to capture everything in the scene unblurred?

Also - if I decide to buy an SLR camera soon is Canon or Nikon the preferred brand? From what I've seen a lot of pro photographers use Nikon but not as many Canon users. Any other brands worth looking at?

Thanks

In short, the aperture in a lens is what controls what is called the "depth of field."
With a smaller aperture opening (high f number), you get more depth of field, which means that more of your background will be in focus.
With a larger aperture opening (small f number), you have less depth of field, which you can see as a blurred background.

Photographers use small depth of fields to bring your attention to the subject. For instance, a single flower in a large field, or a face in the crowd.
With almost all SLRs, the aperture is selectable by the photographer, giving them complete control of the depth of field. The same cannot be said of most point-and-shoot cameras.

I am a Canonnite; I prefer Canon bodies and lenses. You'll probably find the same number of users on this forum who are Nikonians.

When you buy an SLR camera, you are not just buying the body. You are buying into a complete system of bodiesand lenses, and you must decide what kind of shooting you want to do, and who has the best tools for your job.
 
Just remember when your buying a DSLR you are buying a "system" not a brand

Once you pick one and collect some gear its very hard to switch to the other when you decide to upgrade your body. Basically, if you buy a Canon, and over the next 3 years buy a few lenses and a flash, and learn to use the canon menus and shooting style when it comes time to upgrade the camera body, your pretty much limited to another canon if you want to use all your gear and not re-buy it all. Same goes for nikon.
 
The blur behind defined images is called Bokeh and, if you use the lower f-stop numbers you get less depth of field. If you use the higher nubers you get more depth of field.

Personally Im a Nikonian so, I have two Nikons, a D50 and D80.
 
AH!! I use them both about the same. My D50 is my abuse camera and, it goes to work with me. So it gets a little more use. Right now Im trying out the Black&White mode with my D80 just to see how well it works. Most of the time with Dslrs the B&W modes stink.
