I have recently done a quick sketch rendering demo in my company, and I have prepared a step by step screenshots tutorial that I'd like to share here with you all.
Basically it is showing what tools and techniques I use to render a quick concept sketch line drawing using the mouse only. No pen tablet is needed, really.
The time I spent for this one is around 1 hour, including making the screenshots.
In my daily work, I think I must be able to render 8 of these illustrations in one day. They can be used for internal concepts reviews, or even reviewing with the client in the early concept stage.
Of course you can spend more time on more details, but for this demo the purpose is to quickly render the basic coloring,shading,lighting and highlights.
I have used the Eton Axis radio for this tutorial. This product is absolutely a great object to practice your sketching skills. It has basic geometries like cylinders and boxes. Actually I did a sketch demo for this one too, but I don't think I should cover that, as there are many good sketch demos available online already. By the way, my sketch is not perfect (ellipses are off), but it should be good enough
The following 4 Photoshop tools are the most important ones for this particular tutorial:
- Layers :separate the different materials/colors
- Polygonal lasso + Paint bucket : color large surfaces
- Brush : color smaller surface
- Dodge + Burn : lighting and shading surfaces
All right, so here we go.
