The side effect of unlimited photos for me is that I take many, many photos of the same scene trying to get the best one. I especially do this when I am taking pictures of my nieces who will not hold still for more than a second. Fortunately, iPhoto lets me easily compare photos to choose the best and weed out the rest.
To compare two photos in iPhoto:
- In thumbnail view, choose the two photos that you want to compare. (Click the first and Command-click the second one.)
- Click the Edit button on the bottom toolbar. Both photos will open in Edit mode.
With the active photo you can:
- Use all of the editing tools
- Use the arrow keys to move to the next and previous photos in your Library
- Delete the photo by pressing the Delete Key.
- Compare two near-duplicate photos and delete the lesser of the two.
- Crop two near-duplicate photos to see which cropping looks better.
- Compare two photos and then use the arrow keys to look for other near-duplicates.
This technique also works in Full Screen (View / Full Screen from the Menu Bar) giving you larger images to compare.
