Now for an example of bark. This is just an example of one type of tree bark. As I said earlier there are many to choose from and some are smooth and some are more bumby. I choose to do a less smooth one so that you can get the most out of the deomonstration.
1. First for the sake of this demo I started by masking the tree and laying in a simple background because I hate to look at the white of the paper. I also drew some suggestions for the way that the bark will go this is just for my purpose it will be covered in step two. I believe in thinking it through first even though I know that it will be covered. Like laying out your map before you get started on a trip.
2. Second I laid in a flat color. This is the midtone color. I mixed my color from ultramarine blue, burnt seinna, titanium white, a touch of yellow and a touch of red
3. Next I again lay a map out of general lighting and form. This will be greatly covered by texture in this piece but it helps me to visualize where I am going and takes only seconds to do. I just used a darker mixture of the same colors mentioned before.
4. Now I sponge on some texture. This could be done with the airbrush on a low pressure or with a spatter cap. You could alos blow across a clothespin to get this effect. If you have questions about that i would be happy to explain that later. I just like the look of the sea sponge and used that to texure the tree. I use the same dark mixture that I just airbrushed the shadow with as well as a lighter mixture and a mixture of light tan just to add variety.
5. Next I take a no. 4 round brush and use the same paint mixture and start making lines for the bark texture. These look really rough but we will refine them later. It is best to twirl your brush in your fingers as you do this to make thick and thin lines.
