Head Study with Max Ginsburg

Renowned painter Max Ginsburg demonstrates a head study portrait painting while working from a live model. Influenced by great masters such as Picasso, Goya, Kollwitz and Caravaggio, Ginsburg says " I choose to paint realistically because I believe realism is truth and truth is beauty. I derive an aesthetic pleasure in skillfully done realistic drawings and paintings. I believe that realism can communicate ideas strongly and it is this communication that is extremely important to me." Using oil paints, Ginsburg will demonstrate the process of creating a study for future portraits. Active as an illustrious artist and teacher, Max Ginsburg's paintings have received numerous awards and reside in prominent collections around the country.

How Did Papa Cezanne Do It? presented by Jef Gunn

We'll look at the ways in which Papa Cézanne went about developing a painting through conscious changes in drawing and incorporating perspective from multiple views to create a coherent composition. This way of understanding Cézanne's composition, and his contribution to the practice of painting, comes from the 1946 book by Erle Lorain. Jef has taught this as a full class a number of times.

Creating Lifelike Fleshtones In The Alla Prima Portrait with Joanne Mehl

Working from the live model, Joanne Mehl demonstrates the mixing of color to create light and dark value patterns, and how to observe and create warm and cool flesh tones while maintaining value groupings. Many artists struggle with the creation of realistic flesh tones in portrait and figure painting. Since skin reflects light and color, the acute observation of warm and cool tones and perception of subtle hue changes are crucial. So is the ability to group values, in order to create the illusion of form.

Joanne Mehl has been a professional artist and instructor specializing in commissioned portraiture and figure painting since 1985. She currently teaches various classes and workshops at OSA. She is a graduate with Honors in Illustration from The Art Center College of Design in Pasadena.
