As a designer, one is constantly required to sell an idea, be it a client’s or their own.  This week is focused on how to use a technique to communicate and reproduce an idea in an efficient way possible. The Dennis technique is a sketch-up technique that can be used to produce three-dimensional models. The technique can used in Photoshop to come with models that clearly outline features that a designer aims to bring out.  The big concept of the technique is to put a black and white drawing over a colored one and erasing some parts so that the essentials of the design are accented with color.

SketchUp Generated Layers

What I learned through the week is that the technique requires three SketchUp generated layers; line art and shadows, line art only, and color texture and generated shadows. The first of SketchUp is to create the textures and shadow layers that represent the watercolor component of the sketch. An image file is exported to Photoshop and its dimensions and resolutions are reset using some tools within Photoshop. The second step is generating the line art that is similar to pencil and it is laid over the loose watercolor image generated in the first step.

The third step is to create the line art and shadows; this is the step where all the good action takes place. It is where all the erasing of the holes takes place to give the generated image a watercolor look. This technique is quite good if one is efficient with working with Photoshop.
