I have a family portrait session coming up. My package includes an hour with the family shooting and a DVD will full-resolution files for $200.
The family is pretty big -- around 20. I'm wondering what I should charge for additional time (I'm thinking $75 per 1/2 hour?), and I'm also wondering if I should charge a travel fee. I'll be driving about 45 minutes each way.
What do you think I should be charging given the amount of people I'll be shooting, the time we'll probably need to shoot, and the distance I'll be driving?
I charge $120 for the session and will travel for up to an hour for that fee. I have charged an extra $30 to cover my petrol costs for a sitting that was 2 hours away.
I did a family of 20 a while ago and charged and extra $50 as it is very difficult to get 20 people doing the right thing in one shot. If they want separate mini-family-sessions at the same time I'd charge and extra $50 per family.
I sell my prints separately, there are no Files included. That is where I make my moeny.
Just out of curiosity, are you giving them edited files? I ask because I can't see how the fee you are charging could possibly cover your time and expenses if you are spending 6 hours editing and then not selling any prints whatsoever.
