Generating public interest in fish and their biology is often challenging. Many aquatic species are cryptic and largely invisible to the public. Therefore, increasing public awareness of cryptic fishes and elevating their visibility to broad audiences requires innovation. Inexpensive technological advancements now provide fisheries biologists, managers, and researchers with means never before possible for documenting fish in their natural habitat via underwater videography. We investigated cost efficient and simple methods for capturing and creating high quality, high definition, and informative underwater videos that could be used by people with little or no previous experience in videography. We tested 1) a variety of filming equipment including cameras and camera recording settings, lenses, batteries, and memory cards; 2) active and passive camera deployment techniques; and 3) a variety of free and paid postproduction software and compared them for ease of use, expense, and quality of output. Highest quality footage, i.e., highest resolution, clearest, and most stable, was obtained using a GoPro action camera deployed underwater in a stationary position mounted to a metal base plate using a combination of stock and macro lenses, and filming in 4K resolution at 30 frames per second. Final production videos were created using Adobe Premiere Pro.

便宜,水下拍摄高清稀有鱼类

引起公众对鱼类及其生物学的兴趣通常具有挑战性。许多水生物种是隐性的,对公众基本上是不可见的。因此,提高公众对神秘鱼的认识并提高其对广大受众的知名度需要创新。廉价的技术进步现在为渔业生物学家,管理人员和研究人员提供了前所未有的手段,可以通过水下录像在自然栖息地记录鱼类。我们研究了具有成本效益的简单方法来捕获和创建高质量,高清晰度和信息量丰富的水下视频,这些视频可由很少或没有视频拍摄经验的人们使用。我们测试了1)各种摄影设备,包括照相机和照相机记录设置,镜头,电池和存储卡;2)主动和被动摄像机部署技术;3)各种免费和付费的后期制作软件,并对它们进行了比较,以简化易用性,费用和输出质量。使用GoPro运动相机在水下固定部署在固定位置上的GoPro运动摄像机(使用备用镜头和微距镜头的组合,并以4K分辨率进行拍摄)可获取最高质量的镜头,即最高分辨率,最清晰和最稳定。每秒帧数。最终制作的视频是使用Adobe Premiere Pro创建的。使用GoPro运动相机获得的照片,该相机在水下以固定位置安装在水下,并使用备用镜和微距镜头组合安装在金属基板上,并以每秒30帧的速度以4K分辨率拍摄。最终制作的视频是使用Adobe Premiere Pro创建的。使用GoPro运动相机获得的照片,该相机在水下以固定位置安装在水下,并使用备用镜和微距镜头组合安装在金属基板上,并以每秒30帧的速度以4K分辨率拍摄。最终制作的视频是使用Adobe Premiere Pro创建的。
