The 120° panoramic image (and its crop) you see above is titled “Daguerreotype View of Cincinnati” and was captured in 1848 by Porter and Fontayne from Newport, Kentucky. It was created with eight full-plate daguerreotypes and shows a two mile stretch of the Cincinnati waterfront. Codex 99 writes,
The panorama is not only the first photograph of the Cincinnati waterfront but the earliest surviving photo of any American city. It is also the earliest image of inland steamboats, of a railroad terminal and of freed slaves. It may very well be one of the most important American photographs ever taken.
