Behind the scenes: interviewing for Woman

The interviewer's job is to uncover those personal stories that have shaped women's lives – stories that make them unique and which they share with women across the world. It's rare that someone will open up and reveal these stories immediately; they normally need to take time to relax, to forget about the camera, which is why most interviews last an hour or two.

However, says Anastasia, when you've found "the story", there’s no mistaking it. The atmosphere in the room shifts. "I've been to maybe 30, 40 different countries with Human and then Woman," she says. "Often I didn't understand the language. But sometimes without the translator explaining it to me, I can feel that something is happening. These are the moments that will be kept in the film."

All the footage is shot in 4K or better. "4K is now the minimum for an ambitious movie like this one. Skin details are really incredible, with a good lens!" says Hope Production's Marco Strullu, who was in charge of all of the equipment. "The Canon EOS C300 Mark II is a really good choice. This camera is easy to use, not too big, and the dailies quality/size ratio is really good, when we need quality but are capturing thousands of hours of footage."

Framing is also a consideration. "We chose to shoot in the widest frame we could with the EOS C300 Mark II: 4,096 x 2,160," Marco explains. "With this 1.89 ratio, we captured a bit more of the background than in UHD, which is 1.77 ratio. So, if we post-produce the movie in 1.77, we have the possibility to pan in each scene a bit."

For each interview, some location footage is also shot to establish context. It might be the interview subject's home, place of work, or somewhere else of significance to her. The B-camera on many occasions is a Canon EOS 5D Mark IV, using Canon Log to deliver footage as close as possible to that from Cinema EOS cameras as well as capturing as wide a dynamic range as possible (12 stops at ISO400), helping ensure natural results in high-contrast situations such as in the interview setting, with the brightly-lit interview subject in front of a black backdrop.

All of the journalists who carry out the interviews are women themselves. This is a conscious decision on Anastasia's part. "We speak about periods, we speak about sexuality, about the relationship we have with our body, and many women wouldn't open up to a man in the same way," she says. But a number of the cinematographers are men. "In some cultures, it's really important that there are only women present in the room, while in other cultures it may help you to have a man in your team because you need the husband to agree to the interview," she explains. "Having a man there can be reassuring."

That said, they never censor questions for different cultural settings, no matter how taboo certain topics appear. "When we arrive in a country," says Anastasia, "generally, the translator or the fixer says, 'Oh, you know, in our country we don't speak about that,' and we say, 'Yeah, of course.' During the interview, you ask the question anyway and the translator is like: 'No, I think I cannot translate that,' but you insist. Obviously there are women who feel like, 'My God. What?' But there is no exception and it's never happened to me that a woman wouldn't open up. You realise that these are things you never talk about, but once you open the door there is so much to say."

It doesn't always run smoothly. "I remember one woman who was really excited to be interviewed but she couldn't do it," says Marion Gaborit, who's worked as an interviewer and cinematographer in Belgium, Romania, France and the Philippines. "She never answered my questions. I asked about her divorce and she talked about the birth of her daughter. After 45 minutes I gave up."

Occasionally, women decide they don't want their interview to be used – a decision that's always respected. "I had a woman telling me fantastic stories," recalls Saskia. "She said when she was been pregnant for the 10th time, she was playing cards with a friend when she went into labour. She told her baby, 'Calm down, I have to finish the party!' A week later, she said: 'I'm sorry. Just get rid of the interview.' So we did."

Most of the time, though, the interview is a rewarding experience for interviewer as well as interviewee. "I have learned a lot working on this project," says Marion. "I feel lucky because we don't just share words in an interview, it's a really specific moment." Saskia agrees. "Before I started working for Woman, I was going to a therapist, but I stopped," she says. "By interviewing all these women, I started to feel more confident myself. They gave me strength."

In Paris one of the city's few female cab drivers, Clochette, has just finished her Woman interview with Saskia, filmed by Marion. "It went really well," she smiles. "It was a fabulous experience, really fulfilling. And it will be for all the women who see the film too." Saskia believes the film can help bring about positive change: "My hope," she says, "is that everyone who watches the documentary will find one story which makes him or her change their attitude towards women – in their families, at work, in the street, in the metro: everywhere."
