Where was blueprints invented?

History. The blueprint process is essentially the cyanotype process developed by the British astronomer and photographer Sir John Herschel in 1842.

When did blueprint begin?

A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies.

What did architects use before blueprints?

Why do blueprints have to be blue?

A blueprint's signature hue is tied to a chemical process. In 1842, an English photographer, chemist and astronomer named John Herschel discovered that combining ferric ammonium citrate and potassium ferricyanide created a chemical reaction and a compound called blue ferric ferrocyanide (or Prussian blue).

An alkaline or buffered environment causes blueprints and cyanotypes to lose image detail and density. The images first turn yellowish- brown before eventually fading to white. exposed to light. Original blueprints and cyanotypes should not be used in exhibitions.

Are blueprints slower than code?

Performance Concerns

However, in many cases, Blueprint performance is not a problem in practice. Broadly, the main difference is that executing each individual node in a Blueprint is slower than executing a line of C++ code, but once execution is inside a node, it's just as fast as if it had been called from C++.
