Digital Photography School has a forum where people can post tips, projects their working on, etc and someone recently posted a panorama of Niagara Falls. Note: You have to be registered to see the picture, but not to view the comments.
My first attempt at panorama
photoshop did such a great job that I did not have to do any
post procesing at all.
Exposure blend came out perfect
Camera was set on aperture priority
What do you think?
