How to get everything in focus! (photography)?
I just bought a Nikon D7000 DSLR camera. However i hate how most of the photos i take, a certain part of it will be in focus and the other part will be blurry! Is it posssible to make it so everything is clear like in a normal camera?
The selective focus you're seeing is due to using a large aperture (which gives a short depth of field). If you want the same results you were getting from a "normal camera", use f16 or f22.
The two main factors that control depth of field are focal length and aperture. If you shoot with your lens set to its widest focal length and the smallest aperture you can use, you'll have everything in focus. The flip side of that is that you will have a very expensive point-and-shoot if you use your D7000 that way.
What you are asking about is called Depth of Field (DOF) and how to control it. DOF can be very shallow or very deep and anywhere in between.
Shallow:
Deep:
The secret lies in knowing how to control your DOF. There are only 3 factors that affect your DOF:
1) The focal length of the lens used.
2) The f-stop (aka aperture) used.
3) The subject distance.
This site will help you learn about DOF - what it is and how to control it:
http://www.dofmaster.com/dofjs.html You can use the DOF Calculator to compute your DOF for any combination of the 3 factors imaginable.
Although most people assume that using a wide angle lens (think the 18mm end of your 8-105mm zoom here) at a small f-stop (think f16 here) will always result in maximum (deep) DOF that isn't always correct. We'll use the DOF Calculator to show this.
18mm @ f16 with a subject at 1'-6'' DOF will be from 1'-0-1/2'' to 2'-8''. Anything from 0'-5-1/2'' in front of your subject to anything 1'-2'' behind your subject will be in focus. That's a pretty shallow DOF.
18mm @ f16 with a subject at 5'-0'' DOF will be from 2'-0'' to infinity. Anything from 3'-0'' in front of your subject (2'-0'' in front of your camera) to anything behind your subject for as far as you can see - infinity - will be in focaus. That's an extremely deep DOF.
Remember, one of the 3 factors is subject distance and that is all that changed in our examples - from 1'-6'' to 5'-0''.
If you want to see what a really shallow DOF would be use the DOF Calculator and the 105mm end of your 18-105mm zoom lens at the same f-stop and subject distances we used for the 18mm end. HINT: At 1'-6'' your DOF will be a total of approximately one inch.

So you purchased a mid-level DSLR that costs over $1, 000 but have absolutely no idea how to use it properly?
You need to sell your DSLR and buy a nice point and shoot camera instead. You're trying to make it work like a point and shoot anyway, might as well save $900.
It's called large depth of field.
There's something called an "instruction manual" that came with your camera. It's a handy little booklet that will explain how to do this. I suggest reading it.
