William Edward Kilburn was a daguerrotypists that specialized in portraiture and photographed with a quarter plate camera which is smaller than 4x5 inch. For an interesting article on Kilburn with excellent examples of his work see http://image.eastmanhouse.org/files/...0_33_01-02.pdf
The size of Nevil Story Maskelyne's salt images are not 4x5 inch http://books.google.com/books?id=Z7R...rapher&f=false but appear to have been made with a larger camera.
The dry plate process was a revolution in photography which resulted in significantly increasing the market potential for the photographic suppliers. Both Anthony and Dallmeyer started by ordering cameras from manufactures and re-branding them with their own name and, as already shown, Scoville, which had been making 8x10 inch dry plate cameras since the 1870's, was manufacturing a 4x5 inch model for the American mass market in 1881. Only sales would determine the eventual success and permanence of the 4x5 format and it would appear that the US was leading the charge in that regard.
