Architectural Design with SketchUp
Alternatively, you could also have printed the SketchUp view, overlaid it with tracing
paper, and sketched onto it yourself. Then just scan the sketch, scale it and overlay it onto
the rendered image in Photoshop if you go this route.
TIP
Create both images—the rendering and the SketchUp exported sketch—at the same
resolution. This makes it easier to combine them in your image-editing software.

Figure 5.93: Layer arrangement in
Photoshop
To combine the two images, I imported both of them into Photoshop and used
the following layer arrangement (see Figure 5.93). As always, if you use different
image-editing software, adjust this appropriately.
Let’s go through the layers, from bottom to top:
NN

The Background is simply the rendered image.
The Basic Fixes layer is a copy of the background in which I cleaned up some
things (moved some knots around for diversity) and applied the Diffuse Glow filter.
The High Pass Filter layer is a copy of that layer. I desaturated it (to make it grayscale)
and applied the high-pass filter. I then applied the Soft Light blending mode
to this layer, which basically uses this layer to make contrast a bit more interesting.
The White Vignette is a transparent layer onto which I painted white edges and
which has an opacity of 70%. This fades the image out nicely toward the edges.
The next layer is a Hue/Saturation adjustment. I reduced saturation a bit because
colors were a little too bright.
Next are two copies of the sketch. The lower layer of the two has a Soft Light blending
mode (to soften colors even further), and the top one has a Multiply blending
mode (to add crisp linework).
The image created from this process looks like Figure 5.94.
