I was asked a while ago what the biggest enlargement is that has ever been made from a 35mm negative. ‘Good question’ I thought and did some research. Here is what I came up with:
The biggest enlargement ever made of a 35mm photograph was the one for the Kodak Colorama in Grand Central Station in New York in 1977. The original picture was taken by Ernst Haas with a Leicaflex SL and a 50mm Summicron-R lens on Kodachrome 25. The finished Colorama consisted of 20 vertical panels of 3 feet width and 18 feet height for a total size of 18 x 60 feet. This was the first time a 35mm picture had been used for this project. It was a definite testament of the quality of the film and that of the Leica camera and lens.
