For a 1 hour portrait session I provided 15 - 20 fully edited proofs.
I offered 'custom packages', which was business speak for a-la-cart pricing.
The sitting fee for a 1 hour studio shoot was $250 and included a pre-shoot consultation with me and my makeup artist.
The client often bought a session with the makeup artist to apply make up just before the shoot.
The cost of prints varied according to print size, print finish, print media, and print presentation method - matted, framed, framed and matted, standout, canvas, acrylic, metal, etc.
Once a customer met my minimum purchase requirement they could then buy a disc of fully edited image files.
A disc of all 15-20 hi-rez digital file proofs was $1500 and included a print size limited print release (use license).
My average sale goal for each portrait session from 2005 to 2010 was $2000. I retired in 2010 and things cost more now.
Today my average sales goal would be $2500 per shoot.
To just barely stay in business (making minimum wage and barely breaking even $$$ wise) a retail photographer today needs an average sale of about $500 per shoot.
If you want to actually make a little money set your goal for an average sale of $750.
