If you're like me, you probably bought an airbrush because you don't want to waste time doing that most boring of tasks - undercoating and base coating!
An airbrush can be so damn helpful that it will revolutionise your painting workflow so that not only will you get more work done in a smaller period of time, you'll also probably start to enjoy those menial tasks.
If you're like me, you also got straight into airbrushing without a thought for the layering of paint and the slightly odd way in which you need to highlight using an airbrush.
This is called pre-shading.
Here is an example of models that have not been pre-shaded -
Note the flatness of the armour. I'm showing you this on my night lords because pre-shading is so much more important with darker colours. Lighter colours can easily be washed and a great effect can be achieved. Dark blue for example, however, is not a forgiving colour.
My method for pre-shading with an airbrush is simple and effective, allowing for a dark colour of your choosing to go over it flat without too much hassle.
1. Start with a black undercoat.
2. Using a smaller nozzle (I recommend a 0.2mm or 0.3mm), carefully apply a light-medium grey to areas you want to highlight.
In my case, it is from the top, down, as I like to achieve a semi zenithal highlight effect to my flat armour panels.

3. Being extremely careful, use your 0.2 nib to highlight those grey areas to white.

These models are now fully pre-shaded and ready to basecoat. For my Night Lords, I like to basecoat with a 2/1 mix of vallejo model air french blue and signal blue. I find those two together are probably my favourite colour for night lords. Add a drop or two of thinner with it to make sure that pre-shade comes through - signal blue is quite dark and I find its' pigments ro be quite overbearing if not kept in check with some light dilution.
Here are both of those squads fully basecoated.
I hope you enjoyed my lesson. Stay tuned for more midnight clad antics.
