Once upon a time it was considered a no no to have humans in architectural and real estate photography. It was important to show exclusively the space photographed. Fewer elements in the image, the better the space will look and feel.The purpose of the job was to show the space after all, right? I actually did not use talents for a long time because it automatically became the point of attention in the photo, not just because of the person itself but also because of the way they where dressed.
But in many images the sense of scale was missing no matter how good the angle and the illumination was. It could be difficult to really know how big or small the space was. Having talents in my hotel and real estate images really has made this problem disappear. People somehow know automatically the approximate height of a human and can pretty much figure out the sense of space in the image. And, as far as being the point of attention, it can be easily taken care of by having the talent showing up moving. This can be achieved by either using slower shutter speeds in camera or having a blurring effect in post production.
