Viewing full sized photos

In both grid view and list view, iPhoto Library Manager provides a few different options for seeing the full size version of one of your photos.

If you double click a photo, or select one or more photos then hit the space bar, that will open a QuickLook panel that shows you the full size version of the selected photo(s). Note that the QuickLook panel has a button that lets you expand it to fill the screen, which can be useful for a quick, full screen slideshow of multiple photos.

If you want to reveal the actual photo file in the Finder, control-click on a photo, and select either "Show File" or "Show Original File".

If you want to do something with a particular photo in iPhoto itself, control-click on the photo, and choose "Select in iPhoto". That will open up that library in iPhoto and select the image in iPhoto's main window, so you can then do whatever you want with it.

You can also drag an image out of the image browser and drop it directly on to your favorite image editing application, such as Preview or Photoshop, to open the photo in that application.
