At your session, I will check with you if it is OK to use some images from your session as part of my social media, website and portfolio.  There’s absolutely no pressure there and, even if you give me permission, I would never use any partially nude or nude ones unless you expressly tell me that I can.  If you don’t want any images to be shared, then they will only be uploaded to your private gallery for you to view, stored in a secure digital environment and then permanently deleted after 18 months.
