The post claims the pictures are from a Japanese journalist who spent a day in a porn studio in Japan. In this particular shoot, there were 15 to 20 crew members on set that included the producer, three directors, a best boy, a grip, a makeup artist, two camera operators and the porn actors.
Makeup artists are particularly busy redoing the actress makeup after every take.
If the pictures are to be trusted, the set is surprisingly neat with properly stacked sex toys and arranged snacks and lunches.
According to the post, it takes two hours to prepare before shooting starts and two days to complete an entire scene including the extras.
