One of the benefits of digital cameras is the ease to create panoramic pictures.  All you have to do is to over lap about 25% to 33% between the pictures and use a stitching software to bring them together.  Panoramic imaging can capture the essence of the landscape more effectively than a single wide angle picture. 

Stitching softwares are not created equally.  I am going to use 3 stitching software, AutoStitch, Canon PhotoStitch, and Arcsoft's Panorama Maker.  All 3 apps are essentially free as the later two come bundled with some digital cameras. 

Today, I attended the DAS Bazaar, which is yearly fund raising event for the school.  Shooting an event with a lot of people moving is a tough stitching excercise for these apps.  The first picture is the entrance and consists of two pictures - one at F10 and another at F11, which is an easy mistake when you are taking digital images for stitching.  Typically, you want the pitures at the same F Stop.  Getting into F Stop is a topic of dicussion that I will not embark on here.  Just understand that different F Stop makes it VERY TOUGH to get the stitching right as the pictures have a different perspective.

AutoStitch did well on the buildings.  But, you can see the ghost image of a man. 

Arcsoft's Panorama Maker is great with people.  Mu guess is that they put a lot of thought in manipulating people shapes and a good AI behind it (I hate using the word AI - but smart system, which is more accurate, is worse).   Do note the edge of the buildings in the back ground. 

Canon PhotoStitch performed the worse and to think this was my main stitching app.  To be fair, I did not tweak the merge function.  The Canon app offered the best user interface as it allows the user to see the image in the selection process.  With the other two app, you have to remember the photo numbers - urgghhh....

For me, It looks like it is easir to fix the AutoStitch ghosting with a few clone or dodge functions applied in Photoshop.  Smoothing out Panorama building edge artifact is more challenging.  You can forget fixing anything with the Canon output.  Canon does not handle different F Stops well.

OK.  Enough for today.  You can decide for yourself.
