Digital Camera on the Ready

This week I was waiting for Sue to finish selecting her books at the library. The last light of the winter afternoon was casting an interesting color off of the Merced County Courthouse museum.

I snapped four photos that I am happy to share with you on the Flickr side of this blog. When you look at them you will notice the classic error of most amateur photography of buildings.. keystoning.

The buildings seem to sway away from you as see them in the photo. This is why architects often shoot with bellows. This corrects for the parallax of the lens. See these sent me digging into the Kelby books to find the way to correct such a deficit. The way it is done is my running a vertical guide through the photo and aligning it with something that should be straight such as a corner. Then with all of the image selected the photo is skewed to line up with the straightness of the guide. The final step is to "unsquat" the photo so that a compressed photo do not result and consequently do more damage than the alignment. It sounds pretty complicated but really it isn't. The results are tiny but overall it makes a difference.

The suite is loaded.. The next thing to do is to order up ILife 09. I am supposed to be able to get it for ten bucks.. because of the new computer purchase. We shall see.

Love
Pat
