I've seen a lot of artists shy away from painting en plein air on a rainy dismal day. Living in Michigan where we are surrounded by the Great Lakes we have more than our fair share of them as well as bitter winds and temps in winter. If I waited for the optimally pleasant sunny days that California artist's enjoy I'd do precious little outdoor painting. For those of us in Michigan who paint outside regardless of the weather...well, I guess you could say we define ruggedness.
I'm not a strapping young healthy outdoors male as the magazines love to show standing in a snow bank painting. I'm a gray-haired grandmother with a few years under my belt and I still work in the coldest of weather that Mother Nature can throw at us here in Michigan. I thrive on snow banks! For that reason, a little rain doesn't deter me.
"Between Showers", was painted on a breezy wet morning in the Sleeping Bear Dunes National Lakeshore. When the day is sun "lightless" I shift my focus slightly on the palette and process to capture the moody look of the day without adding the dismal. First, I feel it's essential for an artist to have a process that they are familiar with and one that works for them. It makes plein air painting so much easier. Most of my paintings outside are approached in the same manner with only slight shifts. On a sunny day I add more value contrast in color shapes and on a cloudy/rainy day less value and color in my large shapes.
If you look intently at "Between Showers", you see my usual process of layering, i.e.: thin cool darks and lighter valued warmer hues in the light areas, applied more opaquely. The warm and high-keyed lights are, of course, relative to the light that the day offers.
There is actually little "color" in extreme darks and extreme lights. Therefore, most color shows up in the mid-tones of a subject. During cloudy/rainy days those mid-tones have a bias towards the darker end of the spectrum being used for the painting. Since there is no direct light (no sun) on such a day, light diffuses and equalizes across the scene.
Given all this, my process then is:
1. Block in all cool darks, keeping shapes simple and only suggesting local color.
2. Block in light diffused areas, keeping shapes simple, values correct and only suggesting local color.
3. Heighten color and value shifts in mid-toned areas.
4. Work edges
5. Add definition and scroll work where appropriate without going to extremes.
I generally use a number 8 brush when working on an 8x10 panel. This helps to keep shapes simple and doesn't allow a lot of fussing.
Working simply in this way gives me clean and meaningful studies to work from in the studio while capturing the essence of the day. By adhereing to this process my work reflects the day without the dismal.
