One layer was sensitized to record the red-dominated part of the spectrum, another layer recorded only the green part and a third recorded only the blue. British chemist John Herschel made many contributions to the new field. He invented the cyanotype process, later familiar as the “blueprint”. He was the first to use the terms “photography”, “negative” and “positive”. He had discovered in 1819 that sodium thiosulphate was a solvent of silver halides, and in 1839 he informed Talbot that it could be used to “fix” silver-halide-based photographs and make them completely light-fast.
