‘What is a painting?’

Fine Art

Is this a painting?

Fine Art

A painting is a 3D landscape of paint. The texture/relief adds just as much to the uniqueness of a painting as the composition. We visually perceive these indirectly; by the way light is reflected from objects. Painters understand this process

Fine Art

Van Gogh: “… sometimes the material, the nature of the subjects themselves, demands impasto”

Fine Art

Fine Art reproduction research project

●  No model for material appearance description

●  Various aspects to appearance

●  Physical - Light-material interaction

●  Psychophysical – Characteristics eye

●  Psychological – Image processing

●  Attributes:

●  Colour ●  Texture

●  Gloss

●  Translucency

Goal Fine Art reproduction research

Perception

Materials Painting

Materials Print

Different imaging techniques interacting with different layers

•  Developing the access, comparison and data fusion of analytical imagery

•  Reconstruction original painting

sensor

Texture reproduction Printing - Océ high resolution 3D printing technology

●  6 UV-curable inks (T W CMYK) ● Raster (voxels) printer ● Resolution 450 dpi (Apple iPhone 6: 326 dpi)

Materials ●  Color ●  Transparent ●  Conductive ●  Soft/Hard

●  What is the minimal set of materials to (re)produce visual properties on micro scale?
