When I refer to the value scale of the landscape, I'm referencing the amount of illumination in the landscape. So much of what I teach is generalized and this is no different. Every lighting situation is diverse and should be evaluated separately. Having said that, I want to stress the importance of seeing natural outdoor lighting differently from controlled interior lighting. Sunlight and the reflected skylight are very strong and generally create a higher key—brighter saturated illumination. Most of us started painting in an indoor situation either from the still life or portrait. We learned about light falling on form and how to relate this to a value scale running from black to white—with black  representing the absence of light and white the most intense reflective light.

A numbering system is often attached to this scale, facilitating the ability to reference values in our notes. I've always used 0 for black and 10 for white. Other artists have reversed the numbering but I prefer 0 for black, as it represents the absence of light, and 10 for white representing 100 percent light; it just seems logical for my way of thinking. Using this scale we find that 5 is middle value. Since most of us were taught to use this scale, we bring its influence outdoors and relate it to what lies before us in the landscape. This will almost always produce darker paintings that are more kindred to the interior still life than the highly illuminated landscape. For this reason, I've encouraged students to represent the dark masses with value 3, moving the middle value from 5 to approximately value 6.5. Darker accents may be added later that fall below value 3.
 











By moving the scale up to a range of 3 to 10, and massing in the major values representing the dark, middle and light, I end up with a more illuminated painting that better communicates the natural light found in nature. The true job for us all is to see light accurately. By using a value scale, we might better see that light!
