Picasa
This is to picture cataloging what Google Maps is to cartography.

If you have a digital camera you wont find a better way to catalog, browse, display, share and even "tweak" than this free software from Google labs. (Man, I seem like such a Google fetishist in this blog. I'm really not, but they do operate at the outer edge really well and very often.)
I think really I cannot be bothered to write ba really long review of it. Maybe a Zen review.
Yes. A Zen review of Picasa.
It does not take the pictures. It does not make the pictures. It is just the path. The looking glass through which pictures may be seen. And it has red eye reduction.
