However, as discussed below, you can change the privacy state even after pictures are uploaded to Lytro Web.)
Here are some key aspects of understanding privacy options on Lytro Web:
Privacy on Lytro Web depends on the discretion of your friends and family. It's possible for any picture, once shared, to be re-shared by those who can view it (i.e. those who have its URL / weblink)-- including being re-shared on social media services like Facebook or Twitter-- so be thoughtful about which pictures you share, and with whom.
TIP: If you ever find out a picture has been shared more widely than you intended, you have two choices:
you can delete that picture from its Picture Page on Lytro Web, or
you can change the privacy of the Story (group of pictures) containing that picture to "unlisted" on your Lytro Web "My Homepage" and then re-share that newly-unlisted picture.
However, it's best to avoid either of these situations since your original intended audience will find the link you initially shared is now broken.
To verify if a picture or Story is currently public or unlisted, first check the My Homepage or theStory Page to see whether the "Public" or "Unlisted" option has been set for the Story that contains the picture(s) you want to share:
Check the "Settings" button ("gear" icon) to change a Story's privacy state as desired.
Be cautious about making pictures "unlisted" after you share them, since that will break the link you initially shared.
