Post-Processing Techniques are the things which most limit your average shooter these days. All the SLRs we carry right now, Canon EOS Rebels through Nikon digital SLR cameras like the D700 and on to Olympus digital cameras like my trusty E-3, they'll all capture great shots.
So, the rest is up to you and what you do with them, and with the dizzying array of software to choose from these days, it can be hard to know where to start.
Today, let's talk about panoramas. We'll be using a technique often called "pano-stitching" in which we take multiple shots of a scene and then put them together to make a much bigger one.
What to do:
1. Take a series of multiple shots. Make sure there's some overlap. If you have a tripod, this'll be easier, but in adequate light you can easily do it handheld. A couple tips:
A. Put your camera in manual so the exposure is constant through all the shots.
B. Use manual focus, focus on what you intend to be the focal point and then leave it alone for all shots.
C. If you want to avoid having multiple focal areas in the final shot, use a small aperture, like F8 or higher.
For example, here are five shots I took this weekend:

2. Use Photoshop's automate menu to combine them. Going back to at least CS2 Under File -> Automate is an option for "Photomerge." CS2's Photomerge is a little iffy and you'll have to help it out a little, but in CS3 it's top notch and will even let you specify if it's just doing simple stitching, or perspective, or you can even let it just try and figure out which to use.
It'll ask for files, just feed it all the shots you took, hit "OK" and sit back. Once it finishes calculating it'll spit back a file (which'll probably need some slight cropping if you shot handheld). You'll end up with this:

According to Photoshop I should be able to print that picture at 40" wide (and that'sat 300 ppi, too), since it's really 5 full 10 MP shots combined.
