Man, I go treasure hunting for a day and you guys bury me in photos to look at. Great job!!
With all of this talk about filters I thought I would throw in my two cents worth (again, LOL). If you are wanting some really blue skys, the circular polarizing filter is just the ticket. This photo was taken with a CP filter and all I did to it in Elements was adjust the size of the photo so I could post it easily on the blog.
