How to look at iPad's photo folder on a Mac? If an iPad is connected to a PC, then in My Computer, there is a iPad device containing a folder with all photos and videos.

But on a Mac with Lion, this won't happen... Finder doesn't show such device or folder -- even when I choose Preference of Finder to show every device -- is there a way to see the folder like on the PC?

(I just want to edit one video using HandBrake, so won't like to use iPhotos or iMovies to import the video, but just take the video file "as is".)
You should be able to use the OS X tool called Image Capture. It is much more lightweight than iPhoto and is for downloading images and videos from digital cameras, which the iPad technically is as well.
