Metallic and pearlescent paints contain flakes and exhibit strong texture (spatial fluctuations of luminance) and sparkles (rare, extremely bright tiny points). We present an algorithm for calculating these texture and sparkles during image rendering.

This paper presents a survey of significant developments in research on the leaching of oil paint films by organic solvents, from the first systematic investigations carried out in the 1950s to more recent “clinical” studies involving the sampling and analysis of paintings during treatment. Key studies are discussed in the context of an improved knowledge of oil paint chemistry that has develop...

Can a dynamical system paint masterpieces such as Da Vinci’s Mona Lisa or Monet’s Water Lilies? Moreover, can this dynamical system be chaotic in the sense that although the trajectories are sensitive to initial conditions, the same painting is created every time? Setting aside the creative aspect of painting a picture, in this work, we develop a novel algorithm to reproduce paintings and photo...

A 56 year old woman was referred by her general practitioner with ongoing malaise. She had a history of recurrent epistaxis. On examination, there was extensive mucocutaneous telangiectasia (Figure 1). Her father and brother have a history of epistaxis and facial telangiectasia. Her presenting haemoglobin was 6.6 g/dl (normal, 13.0-18.0 g/dl), microcytic picture and ferritin of 3 ng/ml (normal,...

The characteristics of armour paints, historically used to protect ferrous industrial heritage, are explored. Amour paints contain lamellar and highly reflexive pigments micaceous iron oxide (MIO) metallic, leafing aluminium, bound in linseed oil oil–tung mixtures, on an inhibitive soap-forming primer (red lead). It is the first study binding media for historical investigates chemical physical ...
