photography tricks

a little handy dandy feature i recently discovered.
by increasing "saturation" in the included photo editing software,
i can make colors more vivid in a photograph.
it doesn't work as well on people and animals though.
do the buildings look too unnatural?
click on the picture to see an enlargement.
I'd like to try it out on a fruit bowl to see if it comes out more vivid.
if it does, it may look like one of those pictures you see in a calendar or poster.
these were taken with a 4 megapixel camera.

PS these are pictures of the palace of fine arts in san francisco.
