Talent should stand as far away from the backdrop as possible for a number of reasons. One primary reason is to reduce the likelihood of shadows appearing on the backdrop. When the talent is close to the backdrop, the light source can create a shadow that can be distracting and unprofessional in the final image or video. Another reason is depth of field. By creating distance between the talent and the backdrop, photographers or videographers can achieve a blurred background effect, which helps to focus the viewer's attention on the talent. Additionally, standing further from the backdrop can prevent any color or light reflection from the backdrop onto the talent, ensuring accurate color representation. Lastly, it gives more room for the talent to move and interact, allowing for a wider range of shot compositions and dynamics.
