Caravaggio
The Caravaggio Experience, Palazzo delle Esposizioni (2016)
Caravaggio, Judith Beheading Holofernes (1599-1602)
.
Caravaggio Experience is a co-production masterminded by the Azienda Speciale Palexpo and Medialart, in collaboration with Roma&Roma srl, produced by The Fake Factory’s video artists with scientific advice from Claudio Strinati and using the Infinity Dimensions Technology® multi-projection system. The original musical score is by Stefano Saletti, while the fragrances have been designed and supplied by the Officina Profumo – Farmaceutica di Santa Maria Novella.
.
“The Caravaggio Experience is an impressive and original video installation that traces the works of Michelangelo Merisi, using a contemporary approach to the artwork. The use of a sophisticated multi-projection on a massive scale, combined with an original musical score and permeated with fragrances, allowed the visitor to live a unique sensorial experience. The aim is to take visitors to observe and to explore Caravaggio’s work in true depth through a flow of emotions triggered by pure sensoral enjoyment, thus helping to draw a broader audience of experts and non-experts alike to appreciate his work in an absolutely novel fashion.”

“Caravaggio Experience at Palazzo delle Esposizioni in Rome is a multi-sensory video installation on the work of Italian painter Michelangelo Merisi da Caravaggio (1571-1610).

Through the use of a sophisticated multi-projection system, combined with original music composed by Stefano Saletti and fragrances by Florence’s historic Santa Maria Novella perfumery, the visitor has a unique experience at every sensory level and is fully immersed in Caravaggio’s world of the 16th century.”

Grayscale: “Grayscale is the collection or the range of monochromic (gray) shades, ranging from pure white on the lightest end to pure black on the opposite end. Grayscale only contains luminance (brightness) information and no color information; that is why maximum luminance is white and zero luminance is black; everything in between is a shade of gray. That is why grayscale images contain only shades of gray and no color.A digital image usually contains both color information and luminance or grayscale. If you remove the color information, you are left with grayscale, resulting in a black and white image. Grayscale is an important aspect of images, and it is the only portion that is not removed; otherwise, a pure black image would result no matter what color information there is.
.

A digital image is composed of groups of three pixels with colors of red, green and blue (RGB), also called channels in digital imaging. Each channel also contains a luminance value to determine how light or dark the color is. To get a grayscale image, the color information from each channel is removed, leaving only the luminance values, and that is why the image becomes a pattern of light and dark areas devoid of color, essentially a black and white image. Most digital imaging software applications, even the most basic ones, are able to convert an image to grayscale. This is also very important when printing, since it only consumes black ink, as opposed to printing in color, which consumes all three print colors (cyan, magenta and yellow) as well as black.”

Chiaroscuro: “(from the Italian for “light-dark”; or the French “clair-obscur”) describes the prominent contrast of light and shade in a painting, drawing or print, and the skill demonstrated by the artist in the management of shadows to create the illusion of three-dimensional forms.

The point is, solidity of form is only detectable in the presence of light. (For instance, it is only as dawn approaches that objects or figures – hitherto detectable only as slightly darker blobs than their surroundings – acquire volume and a three-dimensional appearance.) And if light emanates from a single source, it illuminates objects according to a specific set of rules. Chiaroscuro describes how the painter depicts the 3-D illumination of objects thus creating the illusion of solid forms.

Tenebrism: (from the Italian word “tenebroso” meaning “murky”) are concerned with the treatment of light and shadow in a two-dimensional painting or drawing. And at first glance a tenebrist painting might look very similar to one containing strong chiaroscuro effects.

Difference between chiaroscuro and tenebrism: Both chiaroscuro and the Mannerist painterly style known as tenebrism (from the Italian word “tenebroso” meaning “murky”) are concerned with the treatment of light and shadow in a two-dimensional painting or drawing. And at first glance a tenebrist painting might look very similar to one containing strong chiaroscuro effects.

However, there is a clear theoretical difference between the two terms. As described above, chiaroscuro is a painterly shading technique used specifically to give 2-D objects a sense of volume: that is, to make them look like three-dimensional solids. Whereas tenebrism is a dark-light compositional technique by which some areas of the painting are kept dark (that is, totally black), allowing one or two areas to be strongly illuminated by comparison.”
