This one is of several people for my HeadShots Portfolio, but normally it's all one person in different poses. It's called a "Proofsheet" because it's a sheet of small 'proofs' from which to choose for purchasing prints, and it's a record of an entire shoot (minus the blinks, awful expressions, etc. lol). It's also called a 'Contact Sheet" from the old film days when negatives would be laid across print-paper and exposed onto the sheet for the same purpose, as a record of a session with one person, couple, or group.
Of course, a client's Proofsheet is private and will never be shown on the internet by the Photographer unless the client signs an Agreement that gives permission to the Photographer to use it as a promotional piece. I'm very private about my clients, don't talk about them to other people, don't show their photos without a signed Model Release, and never ever make prints for people other than the client unless specifically ordered by the client. Privacy MATTERS.
This Contact Sheet/Proofsheet was made in Photoshop, then printed as a print at the lab. Nice record, right?
