I dragged brought my husband to the special Winslow Homer exhibition at Boston’s Museum of Fine Arts. Given my recent interest in watercolor painting, I couldn’t miss Of Light and Air.

Here’s what I learned:

Watercolors fade. These paintings are delicate. That’s why they only display them once every forty years or so—and in very dark galleries. (If you really want to make art that lasts forever, watercolors might not be a great choice.)

Pencil lines are OK, as long as they don’t bleed into the paint. In fact, most of his works were described as “watercolor over graphite.” And being able to draw well really helps. Plenty of modern painters can’t draw, but most artists I admire draw well…really well. So, keep practicing or studying drawing.

Having started as a commercial lithographer and magazine illustrator, Homer could create a realistic image with just a few well-planned lines. In fact, one of his magazine employers sent him to the front lines of the Civil War to draw battlefield images. Talk about trial by fire!

Watercolor paintings are about choices. There is no real white in watercolors. Your white is your paper, so what you choose not to paint is a critical decision.

Things can be represented with just a few brush strokes. Layers matter. Choices. What will you choose to fully depict? What will you simply allude to with a brush stroke or two?

Everyone’s eyesight gets worse as they age. Apparently Homer told people to save rocks for your old age, because “painting rocks is easy.”
