In 10 years of shooting professionally, I've never needed a studio. Since all of my work was architecture and travel-related, most of my shoots were on location somewhere. If I did need to shoot something small, I would convert my kid's playroom into a makeshift studio.
Yesterday marks the big turning point in this journey. I booked a 4-hour studio at TYE in Ft. Lauderdale and shot the lovely and professional model/singer/dancer Allyse Gibson for her portfolio and my stock library.
We'll see what the future brings.
