Digitizing the Films

Each photograph on the 35-mm film was digitized as an image in .tif format at a resolution of 1920 by 1080 pixels at the Woods Hole Oceanographic Institution (WHOI) using a special film transport mechanism and aligned using Combustion 4.0 ( and Shake 5.0 ( software. The photographs were reduced to 600 by 337 pixels using PolyView ( and compressed to 256-color .png images using IrfanView (, reducing the photograph size by about a factor of 6. This photograph size and compression provide reasonable resolution and manageable size for publication. The full resolution digital photographs and the original 35-mm films are archived at the USGS Woods Hole Science Center.
