Highlighting & Shading
As promised, I'll continue the SBS by explaining my process for highlighting and shading.
I should first point out that these latest pics show the mid highlights & the mid shadows only. I haven't as yet applied any upper highlights or deepest shadow tones.
I should also like to point out now that I intend to paint the leather and the skin using oils over acrylics.
I'll start with the uniform first.
I start by applying the mid highlight colour, which I made from mixing Khaki Grey and a drop of Medium Flesh. I applied this starting from the collar and shoulders down, in a series of downward strokes with a relatively dry brush, concentrating on those areas most directly exposed to the overhead sun. I thin my paint mixture with distilled water to a ratio of approximately 7 drops water to each drop of paint. Rather than applying thicker paint, I try to build up the intensity of the highlights by layering multiple thin layers of colours on top of each other.
Once the mid highlights are applied, I turn the bust upside down and look at where the shadows are going to be, and start by concentrating on the darkest areas first (under the bandelero, the pocket flaps and the epaulettes). For my paint mix I mixed English Uniform with Burnt Umber and added several drops of Black Shadow Wash. Once again I keep this mix thin (7:1 ratio) and build up the depepest shadows gradually with multiple applications.
Once I'd done the uniform, I took a break for a while and then started back on the leather. As before I started with mid highlights and then did mid shadows. Because the leather parts will have oils over them, I just wanted to ensure the right colour tones were applied at this stage.
As you can see from the pics, the bust is starting to look a little more complete, but trust me it's not yet half way complete.
The hat and the emu plumes still need to behighlighted and shaded and the face needs more detail.
The next step will be to apply the upper highlights and the deepest shadows, and then carefully begin the process of blending it all together.
Then, I will start on the oils, and finally I'll do the metallics and the "special effects."
As always your comments/ criticisms and questions are welcome.
