When I started class I continued to add value to areas I needed darker and where I wanted it a bit more finished before I took off the masking. When I was satisfied that I had my values dark enough, I let my painting dry and then removed the masking (arrows). Notice how each layer of values looks compared to the white paper that was under the masking, this is how you create light in a painting using the contrast rule.
Detail of the areas that were covered in masking.
Area where the lights will be. In after thought, I probably should have made this area even a bit darker before taking off the masking but it will be okay.
Now with the masking off my painting I can see how areas look and where I need to add more shadow and contrast, for now, however, I started adding some suggested detail. I want you to note that there are no defined shapes in these background subjects, they are just color that suggests something there. don't make a bunch of circles, make overlapping circular shapes leaving some of the under color for highlights and contrast. Save detail for the foreground, only suggestions in the back ground.
I darkened the hair of the worker and did a bit of work on the apron. The dark color is a mix of ultramarine blue and either burnt umber or burnt sienna, the apron was a mix of crimson, napthol red and some blue to darken, I also used this color on the apples and plums in the background.
I also wanted it to look like some light is coming in from the door in the back ground so I added a mix or yellow and burnt sienna to make a golden color that I put on the floor.
This is where I left off in class. While I am now getting into the detail of the painting I am not fussing with it, save the one haired brushes for the final accents but at this point I am still at the suggestion stage. Take your time but don't sit in one place in your painting. Work around and through your painting bringing all of it up at the same time to the same point, otherwise you can run the risk of overworking your painting.
Keep painting and I will see you in class.
