Maybe it’s a strange coincidence, but some of the most beautiful images I captured for Timeline of Historical Film Colors depict ships.
For instance this beautiful toned image from Roald Amundsen’s North Pole Expedition (Norway 1924) on the metallic toning page.

And there are many more to discover…
Update 2016: On the new search page there is a tagging system that allows searching for specific topics, such as ships. The tagging system wil be updated continuously in the next few months.
