Lytro Desktop is designed to help you review and share your living pictures:

• Learn what works by seeing and exploring your living pictures in a larger, more detailed format. This is how you will really find out which approaches to taking light field pictures work best for you.
• Get creative by enabling Perspective Shift or adding Living Filters to your pictures.
• Add captions and titles to help tell a story.
• Share pictures online with your friends and family.
• Delete pictures that don't enhance the story.  
• IMPORTANT: Deleting pictures is permanent-- currently there is no way to re-import pictures from the Lytro camera to the same Lytro Library, nor is there any way to download and import pictures from Lytro Web back into Lytro Desktop.
