For this new pass, you have to mix in the same quantities yellow ochre and Mars black. The result is called "Terre verte" in French (maybe Green ground in English ?). This "grey" is really pleasant to use for still life because is neutral. In Renaissance, this color was used to paint corpses and Christ removed from the cross.
As you can watch on your screen, details are worked. The density of the dark is more or less worked according to the transparency of the colors to come.
The next step will be the glazing when this example will be very well dry.
On this stage, you normally have to work your last under-layer. The objective is to create an image with its contrasts of light and already thinking to the dead layer. Details have to be pushed in the same time that you have to not forget the transparency of the colors that you will have to use. Don't forget with this method, you work for the next step. ^^
It's time now with less turpentine in your medium to work contrast and light with red ochre. Your composition becomes like a watercolor. It's the good moment to see if your composition is OK and maybe, if you have something to change before to continue.
With less turpentine in your medium, oil linen becomes more important and the drying time too. So that's why with this method, it is normal to have 8-10 paintings in progress in the same time.
You were several to ask me how to work like Flemish masters of the 15-16th century. So, I choose this pleasant composition to explain the different steps. I have to write here that I'm not an art teacher and I'm sure that you will be able to find a better teacher than me, because my English is purely horrible. ^^
I prepare my support first. I gessoed it 8 times. 4 layers and I sand. I do it twice.
It's time to draw your composition. Very Important Thing : don't forget to ink your drawing because when you will paint your first under layer with turpentine and ochre, the graphite will disappear. Below, this is the result. Generally, this layer dries very fast.
