Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

Circa 1907. "Pittsburgh by Night." Our second nocturnal view of the Steel City. 5x7 inch dry plate glass negative, Detroit Publishing Company. View full size.
I can recall driving through Pittsburgh in the late '40s with my parents, and this is often how it looked in the daytime as well.
This is taken from the Mt Washington side of the Smithfield St bridge (still standing today). These days there's an awful sports bar complex off to the right and Station Square to the left.
Toward the right we can see the silhouettes of two Pittsburgh landmarks, facing each other across Grant Street: the spiky tower and broad back of H. H. Richardson's Allegheny County Courthouse (1883-1888), and the broader tower of D. H. Burnham & Co.'s Frick Building (1901-1902). Coolness all around!
