All my clients get an individual gallery that is password protected so no other person can view photos. This gallery will have one photo on the log in page that you can see which is in the client viewing section of my website. so you know which gallery to log into to view your photo. No one can access your photo gallery so the photos are not on a public viewing gallery.
Model release forms are only completed if photos are being used by the client for their website, for a magazine etc so model release forms do not apply to portrait photo shoots unless I have asked to use the photos for anything specifically. For instance some of my portrait children photos were put in an editorial for a front cover of a magazine. For this I had full agreement from the parent of the child and also a model release form was completed. Model release forms are only used for this purpose.
