This proposal will use the making of the world's first ever short film shot in High Dynamic Range (HDR) to begin to assess general public interest in the superior visual images produced by novel HDR capture and display technologies and stimulate wide discussion on the major technological advance in film making that HDR may offer. In doing so, the project will provide valuable public engagement experience for the investigators. To achieve this, this three month project brings together internationally leading expertise in HDR imaging and a unique HDR video technology from the University of Warwick with an innovative professional film maker, Entanglement Productions and a new high-tech company specialising in HDR technology, goHDR, to engage with an extensive network of film clubs and their film loving membership.Together the partners will clearly show the revolution in cinematography that HDR technology will bring about to the general public and investigate with the public what the potential social and economic impact of this new technology is likely to be. Through this interaction the investigators will gain direct experience of engaging with the public, and in particular our target audience of film club members, during the course of the film's production and at a public panel discussion on completion of the project. The investigators will also learn key skills from our partner, Entanglement Productions, into just how to make a compelling documentary which clearly explains to the general public complicated research outcomes.We believe the high novelty of the HDR technology and world first nature of this undertaking should generate considerable interest in this project amongst the general public, and our target film loving audience in particular. Well publicised, this should allow major public engagement to occur through the planned engagement activies the partners will be conducting alongside the film making. Furthermore the public engagement skills gained by the partners in creating an HDR film, providing easy, seamless access to such a film to a wide international audience, and capturing and analysing evaluations of the project, will build capacity and capability amongst the partners to facilitate many similar future activities. Such a future variety of available compelling HDR footage will encourage a groundswell of users who wish to experience this new phenomenon, and who subsequently create a large demand for further HDR content. This should result in many additional applications (and markets) of HDR technology well beyond those proposed here.

这项提案将利用世界上第一部以高动态范围（HDR）拍摄的短片，开始评估公众对新颖的HDR捕捉和显示技术产生的上级视觉图像的兴趣，并激发对HDR可能提供的电影制作的主要技术进步的广泛讨论。在此过程中，该项目将为调查人员提供宝贵的公众参与经验。为了实现这一目标，这个为期三个月的项目汇集了国际领先的HDR成像专业知识和来自沃里克大学的独特HDR视频技术，以及创新的专业电影制作人Entanglement Productions和专门从事HDR技术的新高科技公司goHDR，与广泛的电影俱乐部网络及其热爱电影的会员进行合作。合作伙伴将共同清晰地展示电影摄影的革命HDR技术将为公众带来什么，并与公众一起调查这项新技术可能带来的潜在社会和经济影响。通过这种互动，调查人员将获得与公众接触的直接经验，特别是我们的目标观众电影俱乐部成员，在电影的制作过程中，并在项目完成后的公开小组讨论。调查人员还将从我们的合作伙伴Entanglement Productions那里学习关键技能，了解如何制作一部引人注目的纪录片，向公众清楚地解释复杂的研究成果。我们相信HDR技术的高度新奇和这项事业的世界首创性应该会引起公众对这个项目的极大兴趣，特别是我们的目标电影爱好者。通过良好的宣传，这将使主要的公众参与发生在计划的参与活动的合作伙伴将进行与电影制作。此外，合作伙伴在制作人类发展报告影片、向广大国际观众提供方便、无缝的途径观看这种影片以及记录和分析项目评价方面所获得的公众参与技能，将在合作伙伴之间建立能力，以促进今后许多类似的活动。这种未来各种各样的可用的引人注目的HDR镜头将鼓励希望体验这种新现象的用户的激增，并且这些用户随后对进一步的HDR内容产生大量需求。这应该会导致HDR技术的许多额外应用（和市场）远远超出这里提出的那些。
