Why are Professional Photographers so expensive?
This article has been very well received by the photography community, and is published in the December 2009 edition of Professional Photographer Magazine.

In this digital age where everyone has cameras, scanners, and home “photo printers,” we hear this all the time: How do professional (or personal) photographers charge $X for an 8×10 when they cost just $1.50 at the drugstore? Simply put, the customer is not just paying for the actual photograph; they’re paying for time and expertise.

The average one-hour portrait session

First, let’s look at the actual work involved:

Travel to the session
Setup, preparation, talking to the client, etc.
Shoot the photos
Travel from the session
Load images onto a computer
Back up the files on an external drive
2 – 4 hours of Adobe® Photoshop® time, including cropping, contrast, color, sharpening, and backing up edited photographs. Proof photos are also ordered.
2 – 3 hours to talk to the client, answer questions, receive order and payment, order their prints, receive and verify prints, package prints, schedule shipment, and ship.
Possibly meet clients at the studio to review photos and place order. Meeting and travel time average 2 hours.
You can see how a one-hour session easily turns into an eight-hour day or more from start to finish. So when you see a personal photographer charging a $200 session fee for a one-hour photo shoot, the client is NOT paying them $200 per hour.
