i have on occasion opened my studio.....willingly and unwillingly.
i think people are fascinated to be in someone's studio, and it connects them with you and makes them respect you more.
However, if you want bigger or wholesale clients, that you hold off on that until such time as you can present something more professional. Like on the featured sellers and quit your day job photos. Notice, their studios are all very clean neat and orderly. I only saw one shot of a messy soapmaker's studio. and I really appreciated that one! (if you could only see mine on "colorful days" lol.....
