Hmmm I like what I saw with autostich so far… I need to try some more pics with it and see how it does… I did a sweep around the living room and it worked well
One problem you have to look out for is that close stuff will tend to have parallax errors, unless you have a panorama head tuned to your camera. This is actually easier on a smaller sensor since the parallax error will be smaller.
Other things to keep constant are the exposure, focus, focal length, whitebalance. It is also important to prevent lens flare. (You might know this, but sometimes I forget to set all of that on my camera and have problems stitching it later, especially the white balance which Hugin has problems compensating for. exposure can easily be compensated for)
Here is one stitch I did last summer, in IR as well.
