Caption from Oceanus magazine, Vol. 51, No. 1, pg. 55:
Since the new Alvin would be equipped with fiber-optic cables, we wanted to take advantage of that expanded bandwidth and upgrade our imaging systems. When I started on the project in 2006, the big new thing was high-definition video, which we thought would be great, allowing us to shoot video and also collect two-megapixel still images from the same camera. But by 2010, two-megapixel still images were old hat. The latest big new thing becoming available were underwater digital SLR cameras that could take ten-megapixel still images and also shoot HD video. We chose that option for the new Alvin. We still had to put the cameras into housings that could withstand deep-sea pressure to pass the stringent safety requirements for use with Alvin. The optimal housing would use a clear glass dome end-cap for optimal clarity and light transmission. But a higher priority was to guarantee that the housing will not implode, endangering the sub.
