Remote controlled cameras were utilized for a majority of the sex scenes so the set could be more private for the actors, though stunt coordinator Melissa R. Stubbs said in an interview that in some of the wilder scenes, the two lead actors had to spend hours naked in front of a full crew.
Cinematographer Seamus McGarvey revealed that he and his team digitally added in shots of visible pubic hair and that it was not real. Dakota Johnson and Jamie Dornan both wore sheer modesty patches, often used in sex scenes, to cover themselves while shooting.
Dakota Johnson and Jamie Dornan filmed the scenes in the red room the last week of the production's shootings. This way they would be more comfortable with each other since they had spent a lot of time together during the rest of the shoot.
Dakota Johnson took a flogger and several pairs of underwear from the film set. She took the underwear claiming they were too comfortable to leave behind.
Jamie Dornan revealed that he visited a private sex dungeon for research on his Christian Grey character.
