hey everyone!! So i'm just starting to move from a webcam to a DSLR. I Purchased a Canon 2Ti with a basic 18-55 mm Lens. I've been trying to find the right aperture and shutter speed to make EVERYTHING in focus, and not just a certain part. Any advice on how to resolve this problem?
Thanks!!!

This topic is more suitable in EQUIPMENT .
Aperture and shutter speed settings depend on the particular scene you are shooting. There is no single right or wrong answer. Basically, opening the aperture all the way gives you the least depth of field (DoF) while closing it all the way gives you the greatest DoF. Thus, if you want as much as possible in focus at once, simply set the lens at it's highest aperture setting. Again though, it depends on the scene. sometimes you'll want a shallow DoF, other times you'll want a large DoF.
Also a side note to keep in mind, high aperture settings let less light in, so you'll need a faster shutter speed than if you were using a slower shutter speed. Experiment!
A narrower aperture will result in a wider depth of focus, but will also limit the amount of light you receive. Make sure you also decrease your shutter speed or increase the amount of lighting in your scene to counter this effect. Generally you do not want to adjust the ISO setting very much (I keep mine below 800 always) as this will affect your picture quality.
Here's a diagram that might explain better.
Thank you all so much for your help!!! I really appreciate it!

You'll need to lower your aperture (making the aperture circle smaller, but using a higher f-stop) as much as you can and increase the shutter speed. This makes it focus to "infinity", but in some lenses, it might make the actual stuff you want in-focus will be less crisp, so you should be more careful when you use infinity focus.
EDIT: I guess I'm a little late to the party, just restating what everyone else has said... 
Thanks rioforce!!!
