How did photographic lens design evolve from the camera obscura?

The invention of the camera in the early 19th century drove the creation of new lens designs to cover large, flat image planes. Many of these optical challenges were already understood from earlier work with camera obscura lenses. Modern photographic lenses use complex compound lens elements to balance optical aberrations and meet constraints like cost, weight, and mass production.

What we know

• The invention of the camera in the early 19th century led to an array of lens designs intended specifically for photography. [2]
• Problems involving how to cover a large, flat image plane were recognized prior to photography due to the development of lenses for the camera obscura focal plane. [2]
• While a simple convex lens can suffice in principle, practical photographic lenses require a compound arrangement of elements to correct optical aberrations. [4]
• The Petzval objective was developed in 1840 as the first photographic portrait objective lens in history. [5]
