Question: Are The Mosuo Sisters and Through a Blue Lens both documentary films?
Context: Sheila Nevins (born April 6, 1939) is an American television producer and the President of HBO Documentary Films.  She has produced over one thousand documentary films for HBO and is one of the most influential people in documentary filmmaking.  She has worked on productions that have been recognized with over 65 Primetime Emmy Awards, 46 Peabody Awards, and 26 Academy Awards.  Nevins has won 32 individual Primetime Emmy Awards, more than any other person. The Crystal Film (Dutch: Kristallen Film ) is a film award recognising domestic box office achievements in the Netherlands.  The Crystal Film is awarded to documentary films from the Netherlands once they have sold 10,000 tickets.  The award is an initiative of the Netherlands Film Festival and the Netherlands Film Fund to increase media attention for Dutch documentary films, in addition to the existing Golden Film and Platinum Film for Dutch films in general.  They announced the introduction of the Crystal Film on 28 April 2005.  The first Crystal Film was awarded on 21 June 2005 to "Shape of the Moon" (2004).  Since its introduction, the Crystal Film has been awarded to twelve films. Nine for IX is the title for a series of documentary films which aired on ESPN, celebrating the 40th anniversary of Title IX.  The documentaries were produced by ESPN Films in conjunction with espnW, and were intended to have the same creative, story-driven aspect that ESPN Films' other series, "30 for 30", has, with the series focusing on captivating stories of women in sports told through the lens of female filmmakers.  The first film, "Venus Vs.", premiered on July 2, 2013. Low-energy electron microscopy, or LEEM, is an analytical surface science technique invented by Ernst Bauer in 1962, however, not fully developed (by Ernst Bauer and Wolfgang Telieps) until 1985.  LEEM is a technique used by surface scientists to image atomically clean surfaces, atom-surface interactions, and thin (crystalline) films.  In LEEM, high-energy electrons (15-20 keV) are emitted from an electron gun, focused using a set of condenser optics, and sent through a magnetic beam deflector (usually 60˚ or 90˚).  The “fast” electrons travel through an objective lens and begin decelerating to low energies (1-100 eV) near the sample surface because the sample is held at a potential near that of the gun.  The low-energy electrons are now termed “surface-sensitive” and the near-surface sampling depth can be varied by tuning the energy of the incident electrons (difference between the sample and gun potentials minus the work functions of the sample and system).  The low-energy elastically backscattered electrons travel back through the objective lens, reaccelerate to the gun voltage (because the objective lens is grounded), and pass through the beam separator again.  However, now the electrons travel away from the condenser optics and into the projector lenses.  Imaging of the back focal plane of the objective lens into the object plane of the projector lens (using an intermediate lens) produces a diffraction pattern (low-energy electron diffraction, LEED) at the imaging plane and recorded in a number of different ways.  The intensity distribution of the diffraction pattern will depend on the periodicity at the sample surface and is a direct result of the wave nature of the electrons.  One can produce individual images of the diffraction pattern spot intensities by turning off the intermediate lens and inserting a contrast aperture in the back focal plane of the objective lens (or, in state-of-the-art instruments, in the center of the separator, as chosen by the excitation of the objective lens), thus allowing for real-time observations of dynamic processes at surfaces.  Such phenomena include (but are not limited to): tomography, phase transitions, adsorption, reaction, segregation, thin film growth, etching, strain relief, sublimation, and magnetic microstructure.  These investigations are only possible because of the accessibility of the sample; allowing for a wide variety of in situ studies over a wide temperature range. Yair Qedar (Hebrew: יאיר קדר‎ ‎ , born June 13, 1969) is an Israeli filmmaker and a civil-rights activist.His academic training on 20th-century Hebrew literature (Tel Aviv University), propelled him into to The Hebrews — a trans media project on the Hebrew literary canon, centered on filmic portraits of the Hebrew writers.  Eight documentary films were made in this framwork and six others are currently shot.  The documentary films which he produced, wrote and directed are —"Bialik - King of the Jews", "The 5 Houses of Lea Goldberg" and "The Seven Tapes of Yona Wallach", 'the Awakener - the story of Y.H Brener' and 'Simple Woman -Zelda'— as well as the three films which he produced in the project - "Song of loves, Rabbi David Bouzaglo", "the Raven, Zeev Jabotinki" and "Mrs Rachel Bluestein" – aired on Israeli TV, circulated far and wide in cinematheques, community and cultural centers, in Israel and around the world (USA and Canada, Europe, Australia and Russia) earning 10 awards (2016: first prize for filmmaking in the field of Jewish culture by the ministry of Education in Israel, 2015: the "Hebrews" films won the prize for best television project in the Israeli Documentary competition).  The project, both digital and print, offers altogether eight documentary films, a video archive and several books. Through a Blue Lens is a documentary film produced by the National Film Board of Canada.  The film follows interactions between police officers and drug addicts and documents the extreme poverty and suffering many addicts endure. Tsipi (Tsipora) Reibenbach (born 1950) is an Israeli Film director, producer and screenwriter.  Most of her work consists of documentary films dealing with painful issues in the Israeli society such as The Holocaust and Bereavement.  Recipient of the Science and Arts Minister of Israel prize (1996) for directors and screenwriters.  Her film "Choice and Destiny" is one of the most decorated documentary films made by the Israeli industry, among the notable prizes the film won are the Grand Prize in the Yamagata International Documentary Film Festival 1995, two Prizes in the International Documentary Film Festival Amsterdam 1994, and the Scam award (1994) in Cinéma du Réel festival in Paris, France.  She received the DAAD scholarship in 2006 as a distinguished Israeli filmmaker. The Mosuo Sisters is a 2012 documentary film written and directed by Marlo Poras.  It chronicles the lives of two sisters, Jua Ma and La Tsuo, who are members of one of the last matriarchal societies, the Mosuo tribe.  Being an ethnic minority in China, the film explores their journey from working at a bar in Beijing to moving back home to their village in the Himalayas, dealing with the modern world impinging upon the traditional Mosuo culture and way of life. Independent Lens is a weekly television series airing on PBS presenting documentary films made by independent filmmakers.  Past seasons of "Independent Lens" were presented by hosts Angela Bassett, Don Cheadle, Susan Sarandon, Edie Falco, Terrence Howard, Maggie Gyllenhaal, America Ferrera, Mary-Louise Parker, and Stanley Tucci, who served two stints as host from 2012-2014. Zhou Bing (simplified Chinese: 周兵; pinyin: Zhōu Bing , Zhoubing ; born 1 April 1968), famous Chinese documentary director, a PhD from History College of Nankai University, have successively served as the column scenarist and special program production manager of the program titled with “Oriental Biography” and director of special program division of CND Film Group.  Zhou Bing was titled with annual director of Chinese documentary film for three times, and the documentary films created and produced by him amounts to 100 hundred units.  His masterpieces including Palace, Dun Huang and "Road of Millenia Bodhi were" aired on CCTV, National Geographic, SKY TV, History Channel, Arte, and NDR.  Currently he establishes Beijing Oriental Elites Culture Development Co Ltd and works with Tiong Hiew King, the datuk of Tan Sri, Malaysia to setup Sun Media International Co. Ltd and Zero Media International Co. Ltd.  Zhou Bing attempted to join in the development of industrialization process of documentary films with the identity of independent directors.  Zhou Bing is also a Adjunct Professor in the Department of Media and Communication of City University of Hong Kong.  It is art dream of Mr Zhou who has been desiring to realize through images to broadcast Chinese culture and to build oriental aesthetic approach with the images recognized by the world.
