I've always loved panoramas ever since I got my first Olympus camera that had the on-screen display for composing panoramas. It required - and Olympus still stupidly have this requirement - that you use only over priced Olympus memory.
Things have come a long way since with almost every point and shoot now having a on screen guide for doing panoramas and give away free software for it, but what to do with a DSLR?
There are several methods, you can do them yourself in photoshop or any of a number of apps that require you to carefully line up your photos and make little dots on them etc. but none of these compare to Autostitch in ease of use. You literally just point it at your photos and it does it all, you don't even need to tell it what form the panorama takes.
The end result is a good quality JPG (quality is adjustable) that only requires cropping, below are some examples of what I've done with it in the past. It can not be easier to shoot them, no tripods or anything, just line them up.
Click on each for the flickr page, then click on All Sizes to see big versions of each shot.
I'd definitely suggest giving it a try, it's a great way to get more detail in shots, look for example at the last one in detail you'll see Emma in the shot bottom left to give you a sense of scale, that is 6 x 10 meg pixel images stuck together. More examples by me can be seen here and there is a Flickr Group as well with some excellent examples.
Hello.
I would suggest another two progs that do the same:
Photoshop Elements on Windows (just select the photos and it goes) and Hugin on Linux (A bit tricky...it uses some control dots, but it works great).
I think that P Elem is better, because applies some eye correction.
Your photos are great!
