I have a question regarding pre-focus for high Fstop shots. So here's my scenario:
landscape shot, shooting @ F22 to maximize DoF.
I have been told that I need to pre-focus something of interest in the foreground, lock the focus and then recompose and shoot.
Is that how the technique works?

 to gain maximum depth of field in a shot you should set the focus point to the hyper focal distance for the current lens settings. This distance varies based on focal length (mm) and f-stop. There are many charts and articles you can find on the internet to calculate hyper focal distance.
Quickly, hyper focal distance is the front edge of whats in focus (focal plane). Typically the focal plane is 1/3 in front of and 2/3 behind the actual focus point. So focusing at infinity in a landscape shot puts the back 2/3 of the landscape in focus. If you instead focus at the 1/3 point in the landscape you pick up 1/3 in front of that and everything passed that to infinity.
This is confusing subject and the above is quite simplified but your lanscape shots really stand out by using this method.

I think it was great, just been a little busy. I did take the camera out last night, but nothing turned out like I wanted. I need to try and get my LCD on camera close to the same brightness of the PC screen.

Thanks for the great write up. I just got around to reading it, but along with the first post, they make a great introduction to the concept of exposure and how to control it.

The article is well written, but the font and colours on the screen, make for hard reading.

@mmike: the article is excellent, and very much appreciated! Thanks for doing this. You're well on your way to becoming the Ken Rockwell of D40/x.
I'll have to agree with daveograve though -- the white on black (along with the other colors on black) make it very difficult to read. I had to read it in "print preview" mode in browser in order to prevent eyestrain...
Other than that, thank you!

I have always preferred white on black and that was almost the default so I left it, I tweaked on the color scheme.
