Well I have the digital Canon Rebel XT. The files that come off this thing are quite large and are quickly filling up my 80 GB HD on my PowerBook. What are my options as far as external harddrives? Should I get a firewire or USB 2? Any suggestions on size? Can I plug my XT into my PowerBook, and then have iPhoto import the photos onto the external HD? Is there some other program besides iPhoto I should be using to import my images (it seems kinda slow)? Also, why does Finder say the photos are ~3 MB each, but when I open one in Photoshop, it says on the bottom status bar thing that they are ~27 MB each? I know there are a lot of questions there, just answer what you can.
