Yes, that helped a lot. I was able to patch them together last night, although its still noticeable where it was done. I think part of it was that I didn't use the feather plugin right, so I'll have to try it again.
Also, is there a way to easily "straighten" photos in paint (I'm use to using the function in Picasa)? My last photo seems to need this adjustment, as my tripod must have been at a slight angle as I panned across.
Also, when I was working on this I tried to make one of the pictures transparent, so I could fit it over the other one in the correct location. However I found that I was unable to undo the effect without undoing all of the effects before it. Is there a way of doing this that I'm missing?
