Electronic Photography

Video cameras are common in hand-held versions for the home photographer, but many professional video cameras are used to take still photos for professional uses. They obtain high resolution especially through the super VHS format and can be linked to modems for immediate transfer of video or still shots. Specialized cameras with digital-video-image storage systems were used to take the first photographs of the HMS Titanic when she was discovered in her underwater grave in the Atlantic Ocean in 1986. The cameras were attached to an undersea sled called the Argo, and the versatility of the video recording method allowed many scientists means of analyzing the photographic findings. Sophisticated video cameras are also used extensively in medicine, especially in operating rooms to permit several doctors to offer immediate comments on procedures and conditions.
