Use case + rendering

The 210 Red Dot Artar is the historic American alternative-process 4×5 + 5×7 lens — the Goerz Artar formula was the gold standard for offset-printing reproduction work in the mid-20th century. Now favored by alternative-process photographers for cyanotype, palladium, and gum-bichromate work.
