HIDDEN FINE ART WITH IR COLORANTS

We are surrounded by video surveillance cameras that register separately in two light areas: visible to our naked eye - Red, Green Blue record and near infrared record (NIR � Z). In this article, we present quantitative data on the measurement of light absorption for fine art colorants. We expand the theory and practice of Infrared Art by giving examples of artists who paint so-called "infrared pictures" as a new, different creation of a work of art, a new expressive possibility that the artist adapts to his artistic nature, that is, to his expression, and by no means as a new technological possibility to which he will subordinate himself and his art. Infrared Art is a completely new method of creating works of art with regard to the infrared area, that is, it is a discovery and a technology that allows us to create and reproduce works of art with full control over the management of dual images and messages that can be communicated through images, via information that is visible and invisible to the eye. The increasing interest in the question of colors and colorants and their physical properties encourages us not to keep Infrared Art, that is, infrared technology, in the sphere of experiments, but to make maximum use of its applicability in all aspects of visual communication and information communication.
