Design & Photo Album Proofing
Project Proofing is used for projects you want your clients to approve before going to print or produced like wedding albums, collages, designs, etc ...
How it works is you upload the photos (pages for things like photo albums) and assign a client to the project. From the admin you email the client to let them know the project is ready to be reviewed.
They are presented with the thumbnails of the images you have uploaded and when they click to view those photos, they have the options to Approve, Reject and Request Revision. You have the option to disable either the reject or request revision if you don't want one of those available. If request revision is select, they will be prompt to enter the request.
After they have reviewed all the images, they are prompt to notify you on the screen which then sends you an email to let you know they have reviewed the project. At this point they are unable to make any changes.
In the admin area you are able to see how many were approved and how many have revision requests. For the revisions, you can upload a replacement image. When you do, a log is kept of previous versions and any notes made. If there are revisions in the project you can email the client from the admin that re-opens the project and then they can review the revised files.
Here is an article on setting up a Project Proofing section in the manual.
