Question by Tereca: How to use correct aperture?
If I shoot a line of objects around 10ft apart, what would be good to shoot? I live in a small town and cant seem to find anything interesting. I want to be more creative, but can’t seem to find the right thing.
I want to shoot something close up and then something other that is further away in the backround, around 10 feet apart.

Apparently you are trying to work with Depth of Field (DOF) which is the area in focus in front of your subject to the area in focus behind your subject. DOF can be deep or shallow or anywhere in between.
There are only three factors that affect your DOF*:
1) The focal length of the lens.
2) The aperture used.
3) The subject distance.
You can use the DOF Calculator at http://www.dofmaster.com/dofjs.html to compute your DOF for any combination of the three factors imaginable.
* I’m purposely ignoring compact digital cameras that have a tiny sensor that actually affects DOF and makes it more difficult to achieve a shallow DOF. Just concern yourself with the three factors listed.
