After four one-hour sittings with the painting, I was still at a rough stage, but I decided to stop. I felt that I had learned enough from the rough study I had completed, and I didn't want to belabor the freshness of the strokes with details that–given my tendencies–would probably throw off the balance of light and dark.
The light-dark balance had been an ongoing struggle. Below is the original monochromatic underpainting. I had used this image as a reference for keeping my values correct after adding color.
I painted another still life early this, probably in February. Nearly everything about the painting is accidental; I was actually painting the adjacent couch, when my eye was suddenly caught by the beauty of sunlight pouring through the window and onto the coffee table. I wiped off the canvas and began painting that scene instead. I removed one or two bits of clutter from the foreground, but other than that, the arrangement is purely "candid."
This painting is on 8x10 canvas and took about three one or two-hour sittings. I hope to do more still life paintings that capture spilling light this way. The reflections, refraction, translucence, backlighting, and undulating colors all make this painting interesting for me.
