Dennis Anderson
"Pencil and Charcoal Handling Techniques"

Dennis Anderson specializes in capturing daily life activities by elevating these mundane scenes to portray a moment worthy of capturing forever in time.

This demo will focus on the fundamentals of pencil and charcoal handling techniques to implement a strong foundation within the studio. Dennis will work from cellphone pictures that were taken locally during his everyday outings. “What I’m searching for in a particular scene is a feeling, some sense of place, or maybe it’s just happening upon the way sunlight defines forms and creates shadows.”

By demonstrating his perfected handling techniques, viewers will take home valuable tips on changing paintings from recordings to interpretive naturalism—where the representation is referred to as a remembrance of the artist’s impression.




Thursday, January 10, 11:00 a.m. - 12:00 p.m.

Joanne Radmilovich Kollman
"Alla Prima Painting Getting Ready for Max Ginsburg"

Nicole Poole will be the model for this alla-prima portrait demo. Kollman will have handouts of Max Ginsburg’s palette, sharing how Ginsburg neutralizes the warm 3 value reds with the 3 value greens. Kollman will have her portraits and figure paintings on display from the numerous workshops as well as a Ginsburg original of Tony Kollman, one of OSA’s figure models.

At this alla-prima portrait demo there will be handouts to prepare for Max Ginsburg if you are considering the workshop (February 18-22, see our Workshop registration page for more details). We also highly recommend Max’s Sunday demo, free to workshop participants and $50 to the public. It includes a lecture and slide presentation on Ginsburg’s career and large scale Social Justice paintings.

Greg Lewis
"Art Restoration: Repair Secrets Revealed”

The process of repair, restoration and conservation of artworks to their original state is one of trained skill, patience, practice and a passion for detail. Over time, many artworks, if cared for will last indefinitely. However, the ravages of time, exposure to the elements of moisture, sunlight, temperature and of course mishandling, can exact its toll. The art mediums of paintings, prints, sculpture, ceramics, textiles and photography will be presented and discussed, as we reveal the secrets from repair to conservation. Join us as we look at a different side of the art world.
