What is Q Blue Sun?
The agent made of ferric ammonium citrate + red blood salt will be sensitive, so on the sun or ultraviolet light, it will produce a chemical reaction, gradually turn grayish blue from grass green, after washing it will change into royal blue!
※ The construction drawings (blueprints) used in many traditional buildings are also made using this method.
Q Blue Sun Story
In the 19th century, British astronomer John Herchel invented the technology of cyan printing (blue printing) in order to “copy his own notes”. However, it was not widely known until 10 years later. In order to record plant species, a female photographer used a blue sun to produce a series of books and was the first female photographer in the world!
Q will fail? Difficult to get started?
Because the blue sun is needed for the sun (UV energy is different)
Therefore, it is necessary to rely on experience to judge whether the sun is good or not.
But it is not difficult to get started!
