iPhoto does a good job of showing the date the picture was taken but I am moving my photos to an external drive & was hoping there was an easier way to look at dates instead of such a time consuming process. I am also looking at d/cing using the iphoto program due to issues, are you aware if the Image Capture program will show the dates the photos were taken easier? Or perhaps can recommend another program?
Basically, you're moving the files to the Finder. The Finder id the file manager. Here's the limit with that: it treats all files the same, novels, songs, presentations, photos, movies. They're just files. It's like a warehouse full of showboxes. No idea the colour of the shoes inside, just stacks of boxes.
iPhoto manages the Photos. And so is designed to leverage the metadata attached to the Photos not the files. Similarly, iTunes manages the music and so can show you all the songs of an Album together, the Finder can't.
So you're moving from a manager designed for the data you're using and going to one that isn't. That's why it's not easy to see the Exif date.
As for alternatives to iPhoto: what are you looking for? What's the limitations of iPhoto you want to ever come? If you can tell us this we might be better able to point you in a direction.
