Apart from the logistics (not to mention increased time and expense) of having to travel to see every client, we love the "controlled chaos" you can create in the studio. Makes for amazing portraits. Stuffiness nowhere to be found!
Thomas has it right, you have to make the kids a part of the process. We always let them fire the strobes, look at the back of the camera (oops, did I say that out loud?), throw stuffed animals around. We do anything to break through and create compelling portraiture. The experience the children directly influences how much the parents invest in and ultimately treasure what we create.
We also have three boys who have learned daddy's (me) love of cooking. Last weekend, we made Pad Thai, Beef Satay and Tom Yum soup and they gobbled it up!
