Plein-Air Tip: Grouping Tonal Values

An essential composition strategy is to organize values or tones into a light group and a dark group.

In this plein-air painting of a house in Sebastopol, California, my main focus is to create a single unbroken mass of dark for the trees, which then connects to the shadowed parts of the structure and the garbage can.

In this 15 minute video (Link to YouTube) I demonstrate my approach, including a little about perspective, painting procedure, brushes, and compositional design. 

I'm using a limited palette that includes M. Graham watercolor in just four colors: yellow ochre and transparent red oxidetitanium white gouache and black gouache.

Lots of thoughtful artists here so I’ll copy paste my question to this video which Mr. Gurney cross-posted on Instagram:

Me: “Thank you for posting. This relates to the question I’ve been wanting to ask you for weeks - WHY is value massing so important? I’ve read your entire blog, including everything about shape welding, read Arthur Wesley Dow’s book on notan studies, and have generally scoured the internet, so I know HOW to mass values, but still don’t have a deep understanding as to why it is so important and powerful. Can you possibly elaborate? I’d love your insight. Thank you.

Gurney: “The reason value massing is so important is that a simple tonal design has much more impact. You can tell at a glance what is going on. It reads from across the room or when reduced to a tiny size. The parts of the scene that are less important can be relegated to the light-on-light mass or the dark-on-dark mass. The parts that you want the viewer to notice are highly contrasting.”

Me (delighted, and feeling famous): ‘The parts of the scene that are less important can be relegated to the light-on-light mass or the dark-on-dark mass. The parts that you want the viewer to notice are highly contrasting.”’ This makes so much sense, thank you. The convergence of two strategies - having clear values plus that the eye is drawn to the place of most contrast. Some of this still unclear to me so I’ll move the question to your blog. Thanks again.”

Question to everyone here - How do things read clearly from across the room, when we are massing values? Let’s say a dark part of my painting is a sofa and a dog and a shadow and a wall. Massed together, that is just going to look like a dark blob. How does that make the painting more clear? Or is the strategy meant to be used as an extension of establishing the spot of highest contrast, meaning as another way to guide the eye? Thanks so much.

It may sound odd, but this principle is even used in resumes. A scan zone to make the document easier to read and access the information the prospective employer wants. We use this in advertising, textbooks, scientific papers, bank statements etc. Humans like things that are easy to read and then find the highlights. A painting can use the same idea to make it more appealing to the eye and yet quickly readable to the mind.

Tina - Once we "know" something we cannot blot out that knowledge or separate it from coloring our overall impression of the person. The danger is believing what others state as fact. This is a difficult topic that often leads to judgement of the person who believes one way or the other if they choose to make their opinion public. I observe censorship in many aspects of the world. I observe, contemplate, and yes it does add a filter to my thinking about the piece of art or the motive. I choose not to share my personal observation. I do note how quickly a life can be brought up or completely obliterated in the court of public opinion.
