NOVAModeler my English is not good but I suppose you are referring to painting the model.
I do not have pictures of the process in this model. I use post-shading. At base color mix a few drops of white or yellow (n this case I used white) to lighten and apply the mixture on the insides of the panels. Base color, mix black to darken and apply it on the lines of the panels. The two mixtures containing about 80% thinner. Sometimes, for the shadows, I use only black (is the case) also with 80% thinner.
The result of the application of lights and shadows. It's a Spitfire in 1/48 scale but it is the only one with pictures of the process.
The colors used.
XF-83
Lights
Shadows
Top with the XF-82 and already with lights and shadows applied.
and now with XF-81.
