Plein-air painting on the sidewalks of midtown Manhattan is a baptism by fire. You're jostled by the crowds, hustled by street people, choked by diesel fumes, and deafened by sirens. Shadows from the high rises sweep rapidly across any scene you choose.
(Link to video) On Thursday, Jeanette and I joined our friend Garin Baker to paint New York City's landmark Grand Central Terminal. Garin's summer intern, Sean Oswald, visiting from Ohio, accompanied us on the expedition.
Here is my oil painting (left) next to Garin's on the right. This is the second painting that Garin completed within the four hours that we allowed ourselves. The video finishes with a sketch that I did of a passenger on the train. More on that tomorrow.

Backpack Blower

A guy with a backpack leaf blower is blowing some dust and gravel around.
His buddy, a mower guy, goes past. The leaf-blow guy starts blowing his hair, and the mower guy doesn't seem to mind. He stands there and seems to enjoy it.

Then the mower guy leans over and lifts up his shirt a little.
The air velocity of a backpack blower is about 200 miles per hour, enough to put a rippling dent in the mower guy's butt.
Then they go back to work. And so do I.
Chinese step-by-step portrait
A few weeks ago, blog reader Charles Valsechi asked for a step-by-step drawing sequence by an academically trained Chinese artist.
Let's start with the finished drawing by Xubucheng. (Edit) Blog reader ZS has generously translated the Chinese notes in the book, which I'll show in bold after each step, followed by my own observations about what he seems to be doing.
(Translation) "1A. Be sure of the position/alignment of the head, and get the block in right."
1B. Use simple straight lines to mark out the shape/contour of the head, locking in the basic positions of the eyes, nose and mouth and ears. 35 minutes."
(My observation) In the the first step he doesn't copy contours, nor does he place spots. His framework is built from nearly straight line segments bounding important lines at the edges of the form.
He's also looking within the form for big plane changes (brow, cheek, chin) and for feature placement. Since this is an upshot, the lines for the brow, eyes, bottom of the nose and mouth are parallel, slanting downward in perspective. The ear and nose are roughed out in a few simple lines. These lines are drawn with controlled sweeping movements of the arm.
(35 minutes."
3. "Once the features have taken form, use shapes of light and shadow to delineate/differentiate the values, thereby achieving clear and accurate form and overall completion of the drawing. [ Trans. Note: I think he means overall coverage and composition of the picture, all that is left is detailing.] (45 minutes)."
In the penultimate stage, the planes are defined in terms of tone, drawn with parallel lines and a slight amount of smudging.
(Final stage--see first image in post) 4. "While in the process of drawing, always remember to compare the value relationship, structural relationship of the features, taking notes of the prominent/striking features on the face, and constant cross-checking and measurement until the portrait is complete."
(65 minutes)(total time 3 hours)
With the structure of shape, line, tone, and form established, he can resolve the smaller nuances to arrive at the drawing you saw at the opening of the post.
So there you go, Charles, and thanks for translating, ZS. If there's anyone out there trained in this method, I'd welcome your help in the comments.

A White Building in Shadow
Quick question: What color would you mix for the shadow side of a white building on a sunny day with a clear blue sky?
I probably would have answered "cool gray," but I would have been wrong. 
In fact, all the swatches above are from the shadow side of the same building from a single photo. They range from dark green to pink to gray. It's hard to imagine mixing those colors and making them look right.
Did any of you answer "It depends?" If so, you had the right answer.
So what does it depend on? For one thing, the shadow side depends on the color of the sky. It's bound to pick up some of the blue color from there. But the reflected light from adjacent surfaces can be a huge influence, too.

In the photo above, you can see where the four swatches came from. The first swatch came from the top of the near plane. It's greenish because it's getting blue skylight plus green reflected light from the grass. That pink swatch is getting red-orange reflected light combined with blue light. Swatch #3 is lightened considerably by the white reflected light.
And area #4 is slightly more yellow-green than #1 because it's got a wider zone of grass reflecting into it. Here the limits of the camera's sensitivity fails us. The human eye is far more sensitive than the camera, and if you were observing and painting the scene, you'd see and paint these differences even more dramatically.

Survival Guide for Art Students
I met with the editors of Dover Publishing a while ago. They publish a lot of classic books on art instruction from days of yore. I told them that most of what I know about drawing and painting comes from studying their books. They asked me for a list of the ten art instruction books that I thought were most useful, with a blurb about why I love each one.
