INTERIOR RENDERING
This tutorial explains how to create an interior rendering using Adobe Photoshop
and a graphics tablet, along with some pens and markers. The Author, Lee Atwell,
graduated from Coventry University in 2006 with an Mdes in Transport Design. He
has worked for Arup Vehicle Design as an automotive designer and Alias modeller,
as well as completing various freelance contracts. More of Lee Atwells work can

Behind any good
rendering is a good idea sketch. This was sketched in my notebook with a biro.
Keep your lines loose to start with, roughing in the basic shape with light biro
lines. I then start to firm up the lines by going over the them again until I am
happy. I then used chartpak markers (any AD marker is fine) to add to the sketch
with form, colour and graphics. For the grey areas I used a cool grey 3, the
brown is a buff marker. I used the same marker over the top to achieve tonal
variation. The next step is to take a white gel pen or white paint marker to add
the highlights, instruments and other details. Look at products close to you,
you will find that the highlights almost always fall on tight radius corners or
edges.
I often use an underlay for this kind of work, but in this case I used a
reference image. Once you are happy, scan it into your computer at 150- 300 DPI.

Desaturate the
sketch and reduce the lightness so it looks a little more like this. You can
also clean up around the perimeter using the eraser tool (the paths tool can
help you here a lot).
Start working
over the top of the sketch using colours that match cool greys. A cool grey 5
will give you both shadows and highlights by using it on a multiply layer (for
shadows( or a screen layer (for highlights). I have also started to work some of
the highlights back up using a soft brush and painting white on a normal layer.
Make sure this layer is on top of all other layers.
Start picking
out areas of colour working on a multiply layer, these early graphic stages are
important, Photoshop gives you a lot of room for experimentation with graphics
and colour. When I was doing this sketch I was always trying different
variations of colour, texture and graphical break up. These screen shots are the
result of a bit of tweaking, especially layer opacity. I have also picked out
the dash display using a white soft brush at about 10% flow.
