Theodor Scheimpflug
Theodor Scheimpflug (October 7, 1865 - August 22, 1911) was an Austrian army Captain who elaborated a systematic method and apparatus for correcting perspective distortion in aerial photographs, now known as the eponymous Scheimpflug principle. He disclaimed inventing it however, citing an English patent of the early French photographic engineer Jules Carpentier.[1]

- Best known for his elaboration of the Scheimpflug principle, which deals with the area of critical focus in a view camera, although he was not the first to describe this principle and never claimed this to be the case.[1]
- He was also involved in aerial photography, and held several patents in that area.
gollark: You can't just magically extract more energy from the same amount of sky once you do somehow get 100%-efficiency panels.
gollark: I duckduckgoed it. The record solar efficiency is 46%. The usual is apparently about 37%.
gollark: Is it 40%? Might be 10%, I think it's 40%.
gollark: Plants don't need much energy.
gollark: Current solar is 40% efficient. There's not a huge way to go.

Scheimpflug himself disclaimed inventing the rule that now bears his name. The Scheimpflug Principle (or rule or condition) provides guidance on how a camera lens and/or back should be tilted when focusing upon a plane that is not parallel to the film. This short article is intended to provide some historical background and technical information about Scheimpflug and his patent. If Scheimpflug did not invent this rule, who did? Scheimpflug cites only one reference, and that is to the British Patent of Monsieur Jules Carpentier of Paris. In 1901 Carpentier had patented an enlarger for correcting converging verticals. Carpentier made this claim: "I have investigated the law which governs the correlation between the inclination of the plane of the negative and that of the sensitized surface to that of the optical axis of the lens...and I find that the relationship is this:—If the two planes are sufficiently prolonged they must intersect in the plane perpendicular to the said axis and passing through the optical center of the lens.
