Today I added the series "save it for a rainy day" but I also added a photo to landscapes 1 (Nov 2007). You can see it when you scroll down. It's the first photo of Muckross house with the tree in front.
I corrected keystoning in the second shot (Muckross house up closer).
Keystoning is a distorting effect of converging verticals, often in buildings.
It is the result of using a wide angle lens. I corrected this in Photoshop.
Don't forget to click on photos to see a bigger version.
