To repeat with some specifics:
1, manual focus; focus on infinity Never focus on infinity, focus ahead of it but within the DOF determined by your aperture. I recommend one third behind the focus point.
2. NO auto white balance - set it
3. Set aperture to F8 - removes depth of field issues Use anything you like but the deeper the better DOF is not a beast to be feared but tamed
4. Shoot in manual: Meter on the brightest and the darkest - find a median setting then set your shutter speed for that Shoot in RAW instead, if your camera permits it, if not check out the '*'
5. Level the camera Yes, well, not necessary and unfeasible if shooting by hand.
6. overlap images NO less than 25% True if handheld, false if on a tripod (15% at most).
7. NO auto ISO - set it
Try PTGUI for stitching - you can get a 30 day trial.

From experience, trying out and documentationAddendum that is not mentioned here:
All lenses create distortions (especially wide angle). You need to correct this BEFORE stitching.
Focusing can vary within a band and by band This technique is akin to picture stacking.
Lighting can be adapted too, just no so much as to create weird side effects*.
White balance can be set afterward and applied to all shots afterward or by areas.
When shooting by band, the 'rules' say 1-3-5-7-9 bands, middle band being the 'master'.
Experience says: **** that, good for students, not reality.
Be aware that many stitching software get really upset when you shoot the sky, large reflective areas with no detail and pictures that are:
Out of focus
Flowing (should have used a higher speed)
Moving objects (like leaves on top of tress)
Under/over saturated images

Light adjustment:
Mixed: three pictures: -0 -0+ 1+ (Warning: Do not forget to return to -0+) Process as
realistic HDR
Transitional:
Dark to light: two pictures -0+ 1+ Blend (Warning: 1+ becomes -0+)
Light to dark: two pictures -0+ -0 Blend (Warning: 1+ becomes -0)
When moving from dark to light or dark to light the changes may exceed 1 stop, in the case shoot as
realistic HDR and keep the newest correct exposure. Too many folks lose the sky or dark areas for no reason.
Focus tip: infinity is NEVER to be used but in one case: If you are shooting a silhouette of a far object (even that it should not be infinity in my opinion).
DOF tip: DOF extend one third in front of the point of focus and two third behind it. When shooting a panorama select on third behind the point of focus. This applies to all lenses.
If you are a nut... Create panoramas and process them as HDR!!! Easy to do, if you bracket all your shots (3, 5, 7, 9 limit is your camera).
