Well this is what I do.
1. hook camera up to computer to read the CF card (the files are in RAW of course )
2. Open aperture and hit import into the right folder ( go eat lunch cuz this takes a very long time on a mac mini 07 model )
3. look over the photo's and if there are any multiable shoots compare them and delete the bad ones.
4. take all the good shots and do tweak the settings in aperture such as contrast exposure color etc.
5. throw them into Dfine if they were shoot on iso 800 or higher
6. throw them into Nik's sharping software ( forgot what it was called )
7. call it a day and export them into flickr
8. after I have exported the pictures I back everything up with the built in backup features which have saved me at least 2 times
If I don't finish I throw the photo's I didin't get to into a folder called "to do" I almost never leave aperture the whole time!
I love aperture there are great plugins for it. All I would ever need!
