the low quality of 20 th century photos is down to KODAK etc producing film to a price not a quality, and a stack of glass plates is not as convenient for an average person as a roll of film! the speed of film to make it convenient to use also lowered the quality of the final image!
many of these photos can be viewed and downloaded from the Library of Congress web site,, the larger tiff format files are astounding,, you can zoom in and identify crewmembers and count rivets..
The picture was probably taken on a glass plate negative. Some I've seen are something like 10 x 12 inches. So the negative could be larger than the picture on your screen!
I'm guessing your P3 pictures also had large negatives.
I'm always amazed at the really fine resolution of these pictures. 110 yrs old and they look as fine as the b/w shots we used to take out of a P3.
Philadelphia circa 1908: Ships at League Island Navy Yard. Cruisers Minneapolis and Columbia (center) and armored ram Katahdin .
Both the Columbia (CL-12) and the Minneapolis (CL-13) were in and out of service several time during their service years.
When this picture was taken the Columbia had been decommissioned since May 3, 1907 and would return to service on June 22, 1915. The Minneapolis was decommissioned November 7, 1906 and returned to service on July 2, 1917 at the beginning of World War I.
The Minneapolis was decommissioned at the Mare Island Navy Yard in San Francisco Bay on 15 March 1921, and sold on 5 August 1921.
The Columbia decommissioned at Philadelphia Navy Yard on June 29, 1921 and sold January 22, 1922.
The innovative, but weird Katahdin was obsolescent when designed, emulating British harbor rams of the 1870s-80s, and being, like them, underpowered and not very seaworthy. She was downright obsolete by the time she hit the waves in 1896. Immediately after the war she was decommissioned (October 1898). Eleven years later she was struck from the Navy Register and designated as a target. In that capacity, Katahdin was sunk off Rappahannock Spit, Virginia in the autumn of 1909.
