Anatomy of Light

Newberry, Light demo

Newberry Art Tutorials

Understanding the makeup of light and shadow is a fundamental art tool. Indeed, you cannot create forms without it.

Three-Quarters Classic Light

A 3/4’s light is falling on this egg form.  This means that 3/4’s of the object is directly lit and the rest of it is in shadow.

Four Key Elements

Just looking at the form, there are four elements: highlight, mid-tone, core shadow, and reflective light.

In the light: the mid-tone and the highlight are the areas that are being “hit” by the light source.

In the shadow: the core shadow and reflective light.

Mid-tone: The tricky part here is to mold your mid-tones so that they accent the form of the object.  Artists tend to flatten their mid-tones by making them too light, and by making the contrast between the core shadow and the mid-tone too strong.

Transparency – A Key to Spatial Depth in Painting Part 2, Color

Newberry Art Tutorials

This online tutorial is a transcription from a 2002 lecture I gave at the Courage of Your Perceptions Conference (Satellite to the EC’s Vision Scientists’ Conference) in Glasgow, Scotland.Given a two-dimensional surface, transparency and contrast are a means to place identities/forms through spatial depth.

In Part 1 I discussed how this theory works with gray tonal scales and in paintings with limited color range.  Let’s see what happens when we introduce intense colors.

It’s important to note that contrast in color is not so much about light and dark but, rather, it is about color opposites. For example here is a classic color wheel in which opposite colors, also known as complimentary colors, are juxtaposed. Three major contrasts are:
Red vs. Green
Blue vs. Orange
Yellow vs. Violet

Transparency – A Key to Spatial Depth in Painting
Part 1, Black/White

This online tutorial is a transcription from a 2002 lecture I gave at the Courage of Your Perceptions Conference (Satellite to the EC’s Vision Scientists’ Conference) in Glasgow, Scotland.

We have examples of artworks from 30,000 years ago to the present in which artists have worked with spatial depth in their drawings and paintings. I have been fascinated by this phenomenon and, for years, I have asked myself how did these artists achieve these startling effects. The result of my query is the formulation of the concept that:
Given a two-dimensional surface, transparency and contrast are the means to place forms in spatial depth.

Transparency will place the forms in depth away from us, and contrast will raise them towards us.

Imagination is one of the cornerstones of art. Its use can be quietly subtle, or flagrantly push beyond the bizarre, or inspire generations of people to dream beyond their immediate circumstances and envision a world of possibilities.

One of the more quiet ways to use imagination is to recreate a real scene from life, yet include additional real objects to complete the idea of the work. Here, David Gallup created an idyllic setting of the Pacific Ocean replete with dolphins, birds, and surfers.
