Just get rid of iPhoto
It was time to get rid of iPhoto since I have Bridge installed and it has numerous advantages, e.g. easier browsing,
starting Photomatix and other apps easily,
showing the detailed exif data right on the spot not in an extra floating window,
not converting to jpg when I try to copy out,
unable to reach the directory in finder and a hundred more ...
1, I just fired the terminal application and copy out all my original files from iPhoto
cp -r "Pictures/iPhoto Library/Originals/" Pictures/
Now I can reach them with any app.
2, Next step Bridge CS3->Preferences->General->Behavior check in When a Camera is Connected, Launch Adobe Photo Downloader.
Good bye iPhoto!
