Studio sessions provide simple backgrounds and flattering light. They're perfect for people who might not be as comfortable shooting on location around total strangers, or are short on time as this type of setup can be used almost anywhere; living rooms, offices, etc. And as you can see below, my cat approves.
Outdoor locations incorporate natural light with a variety of textured backgrounds. For these sessions late afternoon and early morning allow for beautiful backlight.
Finding interesting walls can be easy in almost any city. Almost every neighborhood offers a distinct variety of textured surfaces.
