The 2.5 minutes long clip was published by Mercedes AMG on its YouTube channel and shows the whole rendering process, from the sketch on paper to the digital rendering in Photoshop.
Even if the video is quite sped up, it can be interesting to identify the main steps and techniques involved in the process.
The sketch is drawn on paper with a ballpoint pen (in this case a simple Bic), starting with light lines and then increasing the lineweight to define the shapes, and adding some basic shading with a black-colored pencil.
The sketch is then scanned and imported in Photoshop CS5, where the rendering is created with an Intuos3 tablet.
The car’s forms are defined by adding subsequent layers of values, in a quite elaborated process.
The colored areas are defined both using vector masks created with the path tools and laying down large areas of color and defining the contours with the eraser tool.
The last touches are a slight rotation of the car into a more dynamic pose, and the color balance and contrast adjustments.
In the final image the underlying hand drawn sketch is still visible, which gives energy and dynamism to the rendering.
